Testosterone Propionate 100 mg/ml

Testosterone Propionate is an androgenic anabolic steroid — a fast-acting ester of testosterone. It is produced in a concentration of 100 mg/ml. Due to its short half-life, it requires frequent injections but starts working quickly and causes less water retention than long esters.
