Price: €39
Manufactured in: Europe
🧪 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
