Testosterone Propionate 100 mg/ml by Hilma Biocare
Due to Testosterone Propionate possessing a brief active-life of 2-3 days, many athletes involved in tested competitions liked the stuff...a lot. Testing is usually based upon testosterone Epitestosterone levels. Though most individuals have a much lower ratio, athletes can have natural ratios of up to 6:1. This is considered a negative test for steroids… usually. By injecting Propionate up to 36 hours before competition, plasma Testosterone levels remained elevated while urine concentrations usually fell within the 6:1 levels. Of course IOC testing protocols would detect any plant origin AAS today. But several groups still simply test for the ratio only.
Testosterone Propionate is considered a fast acting testosterone due to effects beginning in about 1 day. The drug reportedly has all the benefits of other testosterones (quick strength and muscle mass increases, increased training aggressiveness, fast post-training recovery) but caused a distinctly lower level of water retention. Users noted an improved muscle pump and increased appetite after one to two days of administration.
Even with a high rate of aromatization, propionate did not cause gyno as often as other testosterone esters. Users who realize this normally did so due to less frequent injections: Not due to some special quality of the drug.
