Core Effects

Testosterone propionate is a short-acting testosterone ester compound that is widely used for precise testosterone replacement therapy, pre-competition conditioning for athletes, and clinical research due to its rapid onset of action and short half-life .

✅Short -acting mechanism of action :

Rapid release : The propionate ester group hydrolyzes rapidly, quickly releasing active testosterone.

Precise control of blood drug concentration : The half-life is about 2-3 days, which facilitates dosage adjustment.

Rapid clearance : Blood drug concentration drops rapidly after discontinuation, with high safety.

✅Quality advantages of Chinese manufacturing :

Purity Guarantee : Raw material purity ≥ 99.5%, conforming to USP standards.

Crystal form control : Stable α-crystal form ensures solubility and stability.

Chiral purity : Optical purity of chiral centers ≥ 99.8%

✅Global supply assurance :

Cold chain logistics : constant temperature transportation at 15-25℃ to ensure stability.

Multiple packaging options: 1kg/aluminum foil bag, 5kg/drum.

Customs clearance support : Complete export documents such as MSDS and COA
