Stealth Labs Testosterone Propionate 100 delivers fast-acting anabolic performance with unmatched purity and consistency. Each 10 mL vial provides 100 mg/mL of premium Testosterone Propionate, the shortest ester of testosterone, ideal for users who prioritize rapid strength, tight muscle gains, and precise hormonal control.
With an active life of just 2–3 days, Testosterone Propionate offers superior control over estrogen and androgenic side effects compared to longer esters. The fast clearance also makes it ideal for short cycles, mini-cycles, and advanced pre-contest preparation protocols.
Clinical data confirms its high bioavailability and fast absorption. For a deep dive into its properties, refer to this NIH article on testosterone pharmacology.
The typical dose ranges between 100–150 mg every other day (EOD), depending on the user's experience and cycle goals. Because of the short half-life, consistent injection timing is crucial to maintain optimal testosterone levels and minimize hormonal fluctuations.
Stealth Labs Testosterone Propionate is especially popular during cutting phases and recomposition cycles. It stacks effectively with:
Like all testosterone esters, Propionate is susceptible to aromatization, leading to elevated estrogen levels. Common symptoms include water retention, gynecomastia, and mood swings. To control estrogen, users may incorporate Exemestane 25 mg or Arimidex.
Androgenic side effects such as acne or increased aggression may occur, particularly at higher doses.
Because of the short ester, PCT should begin 3–5 days after the final injection. Most athletes respond well to 4 weeks of Nolvadex or Clomid. Consider using HCG during cycle for additional protection of testicular function.
Looking for a verified source of lab-tested propionate? You can find this compound through a reliable supplier of Stealth Labs injectables, with guaranteed USA delivery and purity documentation for every batch.
It is typically injected every other day (EOD) to maintain stable blood levels due to its short half-life of 2–3 days.
It can be used by beginners, but the frequent injection schedule may be challenging. Enanthate or Cypionate may be more beginner-friendly.
Its short ester results in less water retention and allows users to quickly adjust doses or discontinue before competition dates.
Begin post-cycle therapy 3–5 days after the final injection due to the rapid clearance of the Propionate ester.
