Testosterone Propionate 100 - Stealth Labs

Testosterone propionate helped establish injectable androgens as a medical standard during a time when oral and implantable methods were limited. Its three-carbon ester slowed the hormone’s release into the bloodstream, extending its effect and reducing injection frequency. By the 1940s, it was used in male hormone therapy, female reproductive disorders, and even psychiatry. Athletes also adopted it in the 1950s for its muscle-building effects. Though it was later overshadowed by longer esters, it remains available today—often favored for short cycles, contest prep, or inclusion in multi-ester testosterone blends.
