Testosterone Propionate

Subname: Testosterone Propionate USP 100mg

Contents: 100mg/ml Testosterone Propionate USP (10x1ml booster)

Chemical name: 4-androsten-3-one-17beta-ol, 17beta-hydroxy-androst-4-en-3-one

Side Effects: Testosterone is easily aromatized in the body to estradiol (estrogen). The enzyme aromatase (estrogen synthetase) is responsible for this metabolism of testosterone. High estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia. High testosterone levels are likely to produce androgenic side effects, including oily skin, acne, and body/facial hair growth. Men with a genetic predisposition to hair loss (androgenetic alopecia) may notice accelerated male pattern baldness. Testosterone propionate is often considered a painful injection. This is due to the very short carbon chain of the propionic acid ester, which can irritate the tissues at the injection site. Many sensitive individuals choose to stay away from this steroid altogether, their bodies reacting with pronounced pain and a low-grade fever that can last for a few days after each injection.

Administration: The usual dosage among male athletes is in the range of 50-100 mg per injection, administered every second or third day. Similar to other testosterone esters, testosterone propionate is commonly used at a weekly cumulative dosage between 200 mg and 400 mg. This level is sufficient for most users to see exceptional gains in muscle size and strength.

Details: Testosterone propionate is a commonly manufactured injectable form of the primary male androgen testosterone. The added propionate ester will slow the rate of testosterone release 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. By many accounts, testosterone propionate is an older, cruder form of injectable testosterone, rendered obsolete by the slower-acting, more comfortable esters that were developed later than it. Still, those who do not mind the frequent injection schedule find testosterone propionate acceptable. As an injectable testosterone, it is a powerful mass-building drug, capable of producing rapid gains in both muscle size and strength. Testosterone propionate is a modified form of testosterone where a carboxylic acid ester (propionic acid) has been attached to the 17-beta hydroxyl group. The half-life of testosterone propionate is approximately two days after injection.
