Propirow 100 by Crowx Labs is a 10ml injectable solution delivering 100mg of testosterone propionate per ml. Fast-acting oil-based formula. USA-based warehouse. Testosterone Propionate is a fast-acting ester that delivers quick strength, muscle gains, and enhanced performance. Ideal for short cycles and cutting phases, it helps increase nitrogen retention, boost protein synthesis, and maintain lean mass. Due to its short half-life, it requires more frequent injections—typically every other day. Common dosage ranges from 75mg to 100mg per injection, depending on experience and cycle goals. This ester allows for faster hormone level adjustments and less water retention compared to longer esters. For best results, inject consistently and monitor estrogen with proper AI support if needed. Warm the vial slightly before injection to ease the flow and reduce post-injection discomfort. Testosterone Propionate is popular among athletes looking for tighter control, fast results, and a clean finish.
