Core Function | Core Effects

Clostaphylocone acetate is a 4-chloro-modified testosterone derivative . Due to its unique chlorine atom substitution and low androgen properties , it is widely used in the treatment of muscle atrophy, post-burn rehabilitation, and prevention and treatment of osteoporosis .

✅ Mild assimilation mechanism :

Chlorine substitution : chlorine substitution at position 4 reduces androgen activity.

Highly effective assimilation : Retains significant protein assimilation activity (assimilation index 250).

Non-aromatication : Does not convert to estrogen, and has no risk of water and sodium retention.

✅Quality advantages of Chinese manufacturing :

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

Crystal form control : Stable β-crystal form ensures consistent dissolution.

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

Production process and quality assurance

1. Advanced synthesis process :

Chlorination reaction : Selective chlorination at the 4-position, substitution rate ≥99%.

Esterification reaction : acetylation at position 17, esterification rate ≥99.5%

Purification process : Recrystallization combined with column chromatography to obtain high-purity products.

2. Strict quality control standards :

Chemical purity :

Main component content: 99.0%~101.0%
