Testoxyl Propionate 100 is a fast-acting injectable anabolic steroid produced by Kalpa Pharmaceuticals, designed for athletes seeking rapid muscle definition, strength gains, and minimal water retention. Each vial contains 100 mg/mL of Testosterone Propionate – one of the shortest ester forms of testosterone with quick release properties.
This compound mimics the action of natural testosterone, promoting protein synthesis and nitrogen retention. Its short ester requires more frequent injections but results in faster performance outcomes. Studies confirm its efficacy in restoring testosterone levels and enhancing anabolic response.
Due to its short half-life, users typically administer 100–150 mg every other day. A typical cycle lasts 6–8 weeks and may include AI support to manage estrogen levels. For muscle hardening, it's often stacked with compounds like Stanoxyl Depot.
For cutting, many athletes stack Testoxyl Propionate with Primoxyl 100 or Masteroxyl 200. In bulking phases, combining it with long esters like Testoxyl Cypionate can create a balanced test base over multiple weeks.
After a Testoxyl Propionate cycle, a solid PCT protocol is essential. Options include Clomixyl or Nolvaxyl, started 3–4 days post-final injection. This helps restore natural testosterone and avoid rebound estrogen effects.
Testoxyl Propionate should be injected every other day due to its short half-life. Most users take 100–150 mg per injection.
Expect lean muscle gains, increased vascularity, improved strength, and reduced water retention within the first few weeks of use.

I used this at 150 mg EOD for 5 weeks to finish a 10 week blast of cyp 500 mg/wk (15 wk total blast time). I was having great results on the blast and noticed no drop in strength, energy or libido when I switched to the prop. Actually, that feeling of being "on" picked up a little and I made some strength and vascularity gains. The test itself had a nice yellow tint to it and was smooth as butter- no PIP even at 100 mg/ml. I was very happy with this product and will be sure to order again.
