HCG and Masteron Interaction

Synergistic
Mechanism-based 60% confidence

HCG and Masteron have a synergistic interaction with 60% confidence. Masteron helps manage estrogen conversion from HCG. This is a common and recommended combination. Adjust AI dose based on bloodwork — avoid crashing estrogen. Both compounds affect the gonads, so monitoring these systems is recommended.

Compound Profiles

HCG

Human Chorionic Gonadotropin | LH Receptor Agonist

Binds to LH receptors on Leydig cells in testes, stimulating testosterone production with a half-life of 24-36 hours, peak levels 6-12 hours post-injection, and 40-50% bioavailability via SubQ or IM routes..

Half-life: 24-36 hours Typical dose: 250-1500 IU (lower for TRT adjunct, higher for fertility) sexual health, hormonal

Masteron

DHT-Derived Anabolic Steroid | Hardening & Anti-Estrogenic

Drostanolone binds to the androgen receptor with high affinity, promoting protein synthesis and nitrogen retention in skeletal muscle. As a DHT derivative, it cannot be converted to estrogen by the aromatase enzyme, eliminating estrogen-related side effects such as water retention and gynecomastia from the compound itself.

Half-life: ~2 days (propionate), ~10 days (enanthate) Typical dose: 300-500 mg/week anabolic
