Product Description


Testosterone decanoate is a steroid hormone from the androgen and is found in mammals and other vertebrates, testosterone decanoate is primarily secreted in the tests of mails and the ovaries of female, although small amount are also secreted by the adrenal glands, testosterone decanoate is the principle male sex hormone and an anabolic steroid.


Testosterone decanoate plays a key role in the development of male reproductive tissue such as the testis and prostates.

Idebenone Introduction:
Idebenone is a kind of new drug for treating senile dementia and improving mental symptom. Also, it is a better antioxidant in cosmetics and health care than Coenzyme Q10 and Vitamin.
Idebenone is a modified version of coenzyme Q10 (CoQ10), which is absolutely crucial for metabolic function. Without it, the electron respiratory chain breaks and cells cannot produce energy. It is also the only lipid-soluble antioxidant that is synthesized in our bodies. Natural levels of CoQ10 begin to decrease after age 30.
CoQ10 would be a perfect supplement for athletes that expend excessive energy or push the anaerobic envelope were it not for one important detail: under hypoxic conditions (like going anaerobic), CoQ10 becomes pro-oxidative and creates a powerful free radical that can damage DNA, mitochondria, and lipid membranes.
There is a synthetic variation of CoQ10 called ubiquinol, also known as idebenone. It has been formulated to have all the advantages of CoQ10 without the pro-oxidative drawback.

USP Sex Enhance Amino Tadalafil 385769-84-6 For Breast Cancer
Amino Tadalafil Basic Info.:
Product Name: Amino Tadalafil
Synonyms: Amino Tadanafil
CAS: 385769-84-6
MF: C21H18N4O4
MW: 0
Melting point: 280-282°C
storage temp.: -20°C Freezer
Chemical Properties: White Solid
Usage: A drug analog of Tadalafil
Product Categories: Drug Analogues;Intermediates & Fine Chemicals;Pharmaceuticals
Amino Tadalafil Description:
A high-pressure liquid chromatography-diode array detection and multi-mode ionization tandem mass spectrometry (HPLC-DAD-MMI-MS/MS) method was used to identify amino-tadalafil and rimonabant in electronic cigarette (e-cigarette) cartridges. Amino-tadalafil is a drug analogue of the commercially approved ™ (i.e. tadalafil). Rimonabant is a drug that was, at one time, approved for weight loss in Europe (although approval has been retracted), but not in the United States. In addition, poor quality control over the e-cigarette products analyzed here is shown by the presence of nicotine in products labeled as containing no nicotine or by the presence of significant amounts of rimonabant oxidative degradant in e-cigarette products containing rimonabant. Identification was accomplished by comparing the retention time of relevant peaks in the sample with those of standard compounds, in addition to comparison of the UV spectra, mass spectra and/or product ion mass spectra.
Function Of Amino Tadalafil:
Made of natural soybean oil residue extraction. Is the cell membrane of the active material, especially exists in the brain cells.
The main function is to improve the function of nerve cells, adjust the transmission of nerve impulses, enhance memory function, due to its strong lipotropy, absorbed quickly through the blood brain barrier into the brain, help relax vascular smooth muscle cells, increase the role of brain blood flow.
