TestProp 100 - Onyx Pharma

Testosterone propionate, one of the earliest testosterone esters, was initially marketed in the 1930s as the first option with a sustained release. Known for rapid action, it requires multiple injections per week, making it a choice for those prioritizing control over testosterone levels. Used in short cycles or pre-competition, it’s popular for helping athletes achieve a dense, defined muscle look. Some experience soreness at the injection site, a common trait due to its short carbon chain. Despite the need for frequent injections, its effectiveness in lean muscle preservation keeps it a favored choice​.
