Sodium Borohydride Description:
Sodium borohydride is an inorganic compound shown as a white to off-white fine crystalline powder or lump. Rapid reaction with methanol will produce hydrogen at room temperature. It is hygroscopic and easily deliquesced upon absorbing water. Boiling point: 500 °C (vacuum); melting point: 400 °C; soluble in water and lower alcohols, ammonia, insoluble in ether, benzene, hydrocarbons; relative density (water = 1): 1.07; Sodium borohydride is usually used as reducing agent in synthesis of inorganic and organic synthesis. Sodium borohydride has a strong selective reduction, being able to selectively reduce a carbonyl group is to a hydroxyl group without reacting with the carbon-carbon double bond and triple bond reaction. A small amount of sodium borohydride can restore the nitrile to the aldehyde with the excess amount being reduced to the amine.
Sodium Borohydride Uses:
The hydrogen of odium borohydride hydrogen here was-1 thus having a strong reducing property which can reduce some oxidative inorganic. It is mainly used for reducing-COOH to-CH2OH in organic synthesis. It plays such a significant role in organic synthesis that it is called as "universal reductant." It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water.
Sodium borohydride provides organic chemists a very convenient and mild means for reduction of aldehydes and ketones. Before this, people usually use metal/alcohol approach to reduce carbonyl compound. Sodium borohydride enables the reduction of carbonyl of aldehydes and ketones under very mild conditions to produce primary alcohols and secondary alcohols. Reduction procedure is as below: First dissolve the substrate in a solvent (typically methanol or ethanol), then cool with an ice bath. Finally add sodium borohydride powder to the mixture until the reaction is completed. The reaction process can be monitored by thin layer chromatography. If the solvent is not an alcohol, we need to additionally supply methanol or ethanol along with the reaction. Sodium borohydride is a reducing agent with medium strength, and thus exhibiting good chemical selectivity. It only reduces active aldehyde and ketone carbonyl group, and does not react with the ester, amide.
It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water.
Common used reducing agents. It can be used as the reducing agent of aldehydes, ketones and acid chlorides, foaming agent of plastic materials, hydrogenating agent for making dihydrostreptomycin, the intermediate of making potassium borohydride, raw materials of borane synthesis, treatment agent of paper industry and mercury-containing waste water, and also paper bleaching agent.
For the manufacture of other borohydride salts, reducing agents, bleaching wood pulp, and plastics blowing agent.
Nanocrystalline superlattices in gold colloid solution have been prepared by ligand-induction using AuCl3 reduced with sodium borohydride. 
Nucleophilic addition of hydride ion from sodium borohydride is an inexpensive alternative method for the Baylis-Hillman reaction to form [E]-α-methylcinnamic acids.
Sodium Borohydride is used as a reagent in the reduction of amino acids and their derivatives. Also used in the catalysis of ammonia borane dehydrogenation.

Testosterone Propionate Description:
Testosterone propionate is a commonly manufactured, oil-based injectable testosterone compound. The added propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Testosterone propionate is therefore comparatively much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule. While cypionate and enanthate are injected on a weekly basis, propionate is generally administered (at least) every third day. Figure one illustrates a typical release pattern after injection. As you can see, levels peak and begin declining quickly with this ester of testosterone. To make this drug even more uncomfortable to use, the propionate ester can be very irritating to the site of injection. In fact, many sensitive individuals choose to stay away from this steroid completely, their body reacting with a pronounced soreness and low-grade fever that may last for a few days. Even the mild soreness that is experienced by most users can be quite uncomfortable, especially when taking multiple pharmacokinetics of Testosterone propionate injections each week. The "standard" esters like in ection enanthate and cypionate, which are clearly easier to use, are therefore much more popular among athletes.
Testosterone Propionate Function:
Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing Osteoporosis (loss of bone density) and possible protection against heart disease. Testosterone is also responsible for normal growth and development of male sex organs and maintenance of secondary sex characteristics. Secondary sex characteristics are specific traits that separate the two sexes, but are not directly part of the reproductive system, for example: chest and facial hair, a distinguished jaw line, broad shoulders and increased muscle mass. Testosterone binds to the Androgen Receptors (AR), which thus causes accelerated muscle gain, fat loss, and muscle repair and growth. These mechanisms are stimulated by activation of the Androgen Receptors (either directly or indirectly as DHT).
Testosterone Propionate Side effects:
There are many possible side-effects associated with Testosterone Propionate use. This product has a high level of aromatization into estrogen and coverts to DHT (dihydrotestosterone) as well. Testosterone can convert to estrogen, the female sex hormone, creating a high risk of gynecomastia (formation of breast tissue in males). Also, supplementing Testosterone to your body will result in the shutting down of the body's natural production of the hormone. The severity of side effects depend mostly on the dose and duration of circulating free testosterone and it's conversion to estrogen and DHT. Testosterone's anabolic/androgenic effects are dependant upon also dosage; the higher the dose the higher the muscle building effect. Testosterone typically promotes aggressive and dominant behavior.
Testosterone Propionate User Notes:
Testosterone Propionate is actually my favorite form of injectable testosterone. Anecdotally, this is because in myself as well as other users, this short acting ester would seem to produce far less water retention and a quicker onset of gains. The only down side to this particular form of testosterone is that it must be injected frequently, with many users (myself included) preferring to inject it every day or every other day at a dose of around 100 mg.
