Estriol Description:
 
Estradiol, or more precisely, 17β-estradiol, is a human sex hormone and steroid, and the primary female sex hormone. It is named for and is important in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is essential for the development and maintenance of female reproductive tissues but it also has important effects in many other tissues including bone. While estrogen levels in men are lower compared to women, estrogens have essential functions in men as well. Estradiol is found in most vertebrates as well as many crustaceans, insects, fish, and other animal species.
 
Estradiol or oestradiol (American or British English usages), derives from estra-, Gk. οστρο? (oistros, literally meaning "verve or inspiration") and -diol, a chemical name and suffix indicating that this form of steroid and sex hormone is a type of alcohol bearing two hydroxyl groups.
 
Estradiol is produced especially within the follicles of female ovaries, but also in other endocrine (i.e., hormone-producing) and non-endocrine tissues (e.g., including fat, liver, adrenal, breast, and neural tissues). Estradiol is biosynthesized from progesterone (arrived at in two steps from cholesterol, via intermediate pregnenolone). One principle pathway then converts progesterone to its 17-hydroxy-derivative, and then to androstenedione via sequential cytochrome P450-catalyzed oxidations.Action of aromatase on this dione generates estrone, and action of a dehydrogenase on this gives the title compound, 17β-estradiol.
 
Estriol Application:
 
Hormonal contraception:
A chemical derivative of estradiol, ethinyl estradiol with maximum dosage 200 µg, is a major component of hormonal contraceptive devices. Combined forms of hormonal contraception contain ethinyl estradiol and a progestin, which both contribute to the inhibition of GnRH, LH, and FSH, which accounts for the ability of these birth control methods to prevent ovulation and thus prevent pregnancy. Other types of hormonal birth control contain only progestins and no ethinyl estradiol.
 
Hormone replacement therapy:
If severe side effects of low levels of estradiol in a woman's blood are experienced (commonly at the beginning of menopause or after oophorectomy), hormone replacement therapy may be prescribed. Such therapy is usually combined with a progestin to reduce the risk of endometrial cancer.
 
Estrogen therapy may be used in treatment of infertility in women when there is a need to develop sperm-friendly cervical mucus or an appropriate uterine lining. This is often prescribed in combination with clomifene.
 
Estrogen therapy can also be used to treat advanced prostate cancer, as well as to relieve symptoms of breast cancer.
Not all products are available worldwide. Estradiol is also part of conjugated estrogen preparations, such as Premarin, though it is not the major ingredient. (Premarin consists of a large number of estrogen derivatives. As the name indicates, it comes from pregnant mares' urine.
 
Hormone replacement therapy in transgender women:
Main article: Hormone replacement therapy (male-to-female)
Estrogen therapy is also used as part of the hormone replacement therapy for trans women. Either oral or transdermal estradiol is used in higher concentrations during initial treatment and transition; estradiol is continued in lower doses to maintain female-level hormones following gender reassignment surgery.
 
Estriol Blocking Estrogens:
Inducing a state of hypoestrogenism may be beneficial in certain situations where estrogens are contributing to unwanted effects, e.g., certain forms of breast cancer, gynecomastia, premature closure of epiphyses, and inhibiting feminization in female-to-male transsexual hormone treatment. Estrogen levels can be reduced by inhibiting production using gonadotropin-releasing factor agonists (GnRH agonists) or blocking the aromatase enzyme using an aromatase inhibitor, or with an estrogen receptor antagonist.

Dibucaine HCL Description:
 
Dibucaine hydrochloride is a local anesthetic of the amide type now generally used for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted. The drug blocks both the initiation and conduction of nerve impulses by decreasing the neuronal membrane's permeability to sodium ions. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.
 
In combination sodium dibucaine hydrochloride is administered to dogs to induce rapid, humane, painless euthanasia. The euthanasia solution is toxic to wildlife. Euthanized animals must be properly disposed of by deep burial, incineration or other method in compliance with state and local laws.
 
Dibucaine HCL Applications:
 
Spinal anesthesia (high, low, saddle block) and topically to produce surface anesthesia. Eye: To anesthetize conjunctiva and cornea prior to superficial procedures (including tonometry, gonioscopy, removal of foreign bodies or sutures, corneal scraping).
 
Nose and Throat: To abolish laryngeal and esophageal reflexes prior to bronchoscopy, esophagoscopy.

Usage: an oral drug that is used for treating impotence (the inability to attain or maintain a penile erection) and benign prostatic hyperplasia (BPH)
 
Tadalafil Description:
 
Cialis (Tadalifil), a phosphodiesterase type 5 inhibitor, is used to treat erectile dysfunction (ED) and decreased libido in males. Cialis works by aiding relaxation of blood vessels and increasing blood flow in the penis during sexual arousal, resulting in improved erectile function.
Tadalafil is used for Erectile dysfunction and pulmonary hypertension, the rapid absorption after oral administration, 2 hours to reach maximum observed plasma concentrations of average time after administration of (Cmax). Influence of absorption rate and degree is not affected by food tadalafil, so it can be with or without with clothes and food.
 
Tadalafil is an oral drug for the treatment of ED, used in the treatment of erectile dysfunction and premature ejaculation, erectile function impairment and premature ejaculation has very significant improvements. There are over 1500 documents to prove the caused by different causes impotence premature ejaculation, knew the success rate is above 80%, and show its reliable curative effect, through the use of more than 20 million people worldwide, proved its long-term stability, the safety of 25 to 60 minutes of work function to coincide with a time needed for foreplay, knew the time adjustment in the highest drug concentration time, help both husband and wife a satisfactory sex life.
 
Tadalafil Application:
 
Since people who have taken tadalafil within the past 48 hours cannot take organic nitrates to relieve angina (such as glyceryl trinitrate spray), these patients should seek immediate medical attention if they experience anginal chest pain.In the event of a medical emergency, paramedics and medical personnel should be notified of any recent doses of tadalafil.
 
Tadalafil is metabolized predominantly by the hepatic CYP3A4 enzyme system. The presence of other drugs which induce this system can shorten tadalafil half-life and reduce serum levels, and hence efficacy, of the drug.
 
Tadalafil has been used in approximately 15,000 men participating in clinical trials, and over eight million men worldwide (primarily in the post-approval/post-marketing setting). The most common side effects when using tadalafil are headache, stomach discomfort or pain, indigestion, burping, acid reflux, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects reflect the ability of PDE5 inhibition to cause vasodilation (cause blood vessels to widen), and usually go away after a few hours. Back pain and muscle aches can occur 12 to 24 hours after taking the drug, and the symptom usually disappears after 48 hours.

Methenolone is perhaps only half as potent by the oral route as by injection, so dosages need to be high, at least 100 and preferably 200-300 mg per day, but if that can be afforded it is an excellent drug. It is unusual among oral steroids as being Class I, binding well to the androgen receptor. 
 
Methenolone Acetate Applications: 
 
Primobolan (methenolone acetate), all things being equal, is an excellent oral steroid drug. Unlike most other oral steroids, Primobolan is not 17-alkylated and does not have liver toxicity problems. 
Primobolan is toxic to the liver, especially the oral versions, although the toxicity is gradual and slight. Acne and hair loss can occur with long-term use. 
Primobolan is a good base compound in a stack and can produce results just slightly below that of nandrolone and is best used in a cutting stack. Because Primobolan doesn't aromatize, there is no use for Clomid or Nolvadex.
Primobolan Acetate is very strong, the synthesis of the metabolism and male characteristics is very low, making it the best choice for the game. The drug for women is very good!

Anabolic Oral Steroid Hormone Powder Oxandr Anavar
 
Oxandrolone Description:
 
Anavar, also called Lonavar, Oxandrin, Vasorome, its chemical name is 17beta-Hydroxy-17-methyl-2-oxa-5alpha-androstan-3-one. Anavar is a kind of oral testosterone drugs synthetised by actively metabolizing anabolic. It researched that 20mg Oxandrolone daily dose has an effect on weight gaining and rehabilitation muscle for who encounters large area burnt.
Anavar, which comes out of androgenic character, can cause retention of nitrogen, potassium and phosphorus, and promote anabolism and inhibit excessive catabolism. Anavar is widely used for boys who come across abnormal growth and late puberty, and also girls who encounter congenital ovarian hypoplasia.
 
Anavar absorbed rapidly according to intestines and stomach. Its metabolites and unchanged oxandrolone excreted by the kidneys, and small amount exclude from gastrointestine.
 
Oxandrolone Applications:
 
Anavar has often been called a weak steroid. Part of the reason for this is that use of a Class I steroid alone never is maximally effective. The other cause is that bodybuilders and authors in the field sometimes make unfortunate and unreasonable comparisons when judging anabolic steroids. 
 
Oxanabol(Anavar, Oxanabol) has given optimistic consequences in taking care of anemia and hereditary angioedema. Proven studies though have given links linking expanded use of the medicine and problems of liver toxicity like to those found with additional 17α-alkylated steroids. Yet in little dosages, numerous patients shown gastro-intestinal troubles such as bloating, nausea, and diarrhea. Oxanabol(Anavar, Oxanabol)`s specificity targeting the androgen receptor predestined that, unlike lot other steroids, it had not been seen to give stunted development in teens people, as well at usual measure not often observed clear masculinising reactions external of stimulating strength growth. Oxanaboldoes not aromatize at any measure, and is not without problems ingested into DHT or estrogen. As such, a typical dose of 20-30 mg offered eminent androgen levels for up to eight hours. To enlarge use, bodybuilders classical "stacked" the Oxanabol(Anavar, Oxanabol) with others such as , advance enhancing corp power increase.

Follistatin 344 Description:
 
Follistatin is fascinating protein that can increase muscle mass beyond natural potential by suppressing myostatin. Scientists first identified follistatin while examining porcine (re: pig) follicular fluid in the ovaries.
Follistatin is naturally found in the skeletal muscle of almost all mammals with advanced or developed characteristics, such as humans, rodents, and cows. Follistatin is high in the non-essential amino acid cystine but unlike most proteins discussed in the fitness world, follistatin has carbohydrates attached to it.
Follistatin, specifically Follistatin 344 (FS344), quickly gained popularity in the bodybuilding community as a potential supplement to rapidly increase lean tissue mass. Another protein, follistatin-related gene (FLRG) acts on similar pathways as FS344 regarding its muscle building properties. Increased lean tissue mass could give a bodybuilder an advantage in a competitive setting and be the differentiating factor between first and second place.
 
Follistatin and Muscle Growth:
 
Follistatin works by binding to and inhibiting transforming growth factor-β (TGF-β) peptides such as myostatin which is responsible for regulating and limiting muscle growth. [3] It's also worth pointing out that myostatin may have a regulatory role in skeletal muscle fibrosis; too much myostatin can impair tissue function and cause chronic disease in vital organs, tissues, and bone marrow. 
 
Follistatin 344 Applications:
 
FST(Recombinant Human Follistatin):Period in infants and children, continued growth of muscle, hardly any myostatin,,However, as people move towards adulthood, the number of stabilizing muscles, myostatin to come into play.Scientists have found, named follistatin (follistatin) to the same protein myostatin sticking together, blocking its inhibitory function, and promote the growth of muscle fibers. Follistatin promote muscle growth due to the unique mechanism of action, FST joint use of steroids, IGF has better results . It only acts on muscle tissue , after use will not cause the proliferation of other tissue cells.

MK-2866 (Ostarine) Description:
 
Ostarine (MK-2866) is a SARM developed by GTx for the prevention and treatment of muscle wasting. It may eventually be a medical prescription for the prevention of cachexia, atrophy and sarcopenia as well as for Hormone or Testosterone Replacement Therapy.
As a research chemical, Ostarine belongs to a class of chemicals know as SARMS or selective androgen receptor modulators. SARMS create selective anabolic activity at certain androgen receptors. In comparison to testosterone and other anabolic steroids, the advantage of SARMS, is they do not have androgenic activity in non-skeletal muscle tissues. Ostarine is effective in maintaining and increasing lean body mass.
Ostarine is a potent and tissue-selective androgen receptor modulator (SARM) for treatment of conditions such as muscle wasting and osteoporosis. These patent products for research purposes only use. Ostarine (GTx-024, MK-2866, Enobosarm, S-22) is an orally bioavailable nonsteroidal selective androgen receptor modulator. Therefore, ostarine can be used for treatment of conditions such as muscle wasting and osteoporosis.

4-DHEA Description:
 
4-DHEA is a naturally occurring DHEA isomer. It's structure closely resembles regular DHEA but the double bond in the 4th position dramatically changes its effects.
 
4-DHEA readily converts to 4-androstenediol, rather than 5-androstenediol, boosting its anabolic potency more than 2x over regular DHEA. (6-8, 11) 4-DHEA is also expected to have a higher conversion rate to test compared to regular DHEA. (6, 7) The 4-DHEA also lacks the calorie burning thermogenic properties, therefore offering superior calorie retention for a bulking effect. (4) This increased anabolic potency and reduced thermogenic action will lead to noticeable gains in strength, lean tissue growth, and weight gain.
 
4-DHEA will have mild estrogen conversion that can be easily balanced with a non-aromatizing steroid like androsterone or 1-DHEA. Overall gains will be similar to the original "4-AD" banned in the 2004 Steroid Control Act.
 
As with the other DHEA isomers, 4-DHEA is naturally occurring and non-toxic. (9) Side-effects such as oily skin or reduced fertility are considered mild and temporary. The most notable side-effect would be suppression of natural test production, which makes post cycle therapy necessary after a cycle. Overall 4-DHEA is a very safe and effective lean muscle building agent.
 
The only downfall to 4-DHEA is its high cost due to the high dose that is required to see significant muscle building effects.
 
4-DHEA Applications:
 
4-DHEA is a naturally occurring non-methylated (non-17AA) PRO-steroid. Although 4-DHEA can aromatize to estrogen it is probably not enough to cause high estrogen related side-effects.
 
Overall results will be similar to or the original 4-AD banned back in 2004. Higher doses of this compound will produce fairly lean gains in muscle mass, with moderate improvements in strength. This product may produce some bloat from the estrogen conversion, which could be countered by administering an aromatase inhibitor, but this will largely defeat the purpose of using this compound to begin with.
 
Since this compound is naturally occurring and non-methylated overall side-effects will be fairly mild. However, high doses may also lead to oily skin, acne and increased blood pressure. Because this steroid is non-17AA there should be less concern about it negatively affecting the HDL/LDL ratio.
 
Because this compound can convert to testosterone it can also convert to DHT and other 5A-reduced metabolites. This can serve as a good stack with progestational or relatively non-androgenic compounds that may create problems with libido or gyno because of lacking androgenic potency.

Product Description Of Formestane:
 
Formestane was the first selective, type I, steroidal aromatase inhibitor used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women. Formestane suppresses estrogen production from anabolic steroids or prohormones. It also acts as a prohormone to 4-hydroxytestosterone, an active steroid which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor. It is listed as a prohibited substance by the World Anti-Doping Agency for use in athletes. 
 
Formestane has poor oral bioavailability, and thus must be administered forthnightly (bi-weekly) by intramuscular injection. Some clinical data has suggested that the clinically recommended dose of 250mg was too low. With the discovery of newer, non-steroidal and steroidal, aromatase inhibitors which were orally active and less expensive than formestane, formestane lost popularity. 
 
Currently, formestane (categorized as an anti-estrogenic agent) is prohibited from use in sports in accordance to the regulations of the World Anti-Doping Agency. It is not US FDA approved, and the intramuscular injection form of formestane (Lentaron) which was approved in Europe has been withdrawn. 
 
Formestane (Lentaron) is a type I, steroidal aromatase inhibitor. It is used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women. It is available as an intramuscular depot injection.
 
Formestane is often used to suppress estrogen production from anabolic steroids or prohormones. It also acts as a prohormone to 4-hydroxytestosteron, an active steroid which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor.
 
Formestane has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
 
Formestane Applications:
 
Formestane is a second generation, irreversible, steroidal aromatase inhibitor. It inhibits the aromatase enzyme responsible for converting androgens to estrogens, thereby preventing estrogen production. Breast cancer may be estrogen sensitive or insensitive. A majority of breast cancers are estrogen sensitive. Estrogen sensitive breast cancer cells depend on estrogen for viability. Thus removal of estrogen from the body can be an effective treatment for hormone sensitive breast cancers. Formestane has been targeted specifically for the treatment of postmenopausal women. Unlike premenopausal women who produce most estrogen in the ovaries, postmenopausal women produce most estrogen in peripheral tissues with the help of the aromatase enzyme. Formestane, an aromatase inhibitor, can thus help to decrease the local production of estrogen by blocking the aromatase enzyme in peripheral tissues (ie. Adispose tissue of the breast) to treat hormone sensitive breast cancer.
