🧪 Product Overview

Methyltestosterone 25 mg provides a fast-acting, 17-α-alkylated analog of testosterone used in research for strength-gain modeling, anabolic signalling, and androgen–estrogen conversion studies.

Its oral bioavailability (~70%) allows precise molar dosing in non-injectable studies, while a short elimination half-life (~3 h) supports high-resolution pharmacokinetic tracking. Readily aromatising, it serves as a comparative compound in pure-androgen vs. mixed-hormone pathway exploration.

✅ Key Research Highlights

• High anabolic potential: In-vitro binding at ~45% of DHT affinity (≈2× testosterone), supporting strong protein-synthesis models

• Rapid strength and mass gain: 15 mg/day for 6 weeks outperforms placebo in body-weight and leg-press trials

• Androgen–estrogen contrast: Aromatisation enables side-by-side comparison of fluid-retention and gynecomastia pathways

• Efficient oral dosing: Despite hepatic metabolism, 70% oral bioavailability ensures reliable delivery

• Short half-life: ≈3 h clearance allows frequent sampling and detailed PK/PD curve analysis

• WADA classification: Listed as an S1 anabolic agent; long-term urinary metabolites detectable for over 6 days

🔬 Suggested Laboratory Applications

• Strength-enhancement and lean-mass growth research

• Post-androgen receptor response studies

• Estrogen conversion and fluid-retention modeling

• Hepatotoxicity and lipid profile alteration experiments
