17a-Methyltestosterone 25 mg Astera Labs

Description

17a-Methyltestosterone 25 mg Astera Labs — 17α-methyltestosterone — the first orally-bioavailable androgen. Aromatises to potent methylestradiol; historical compound with safer modern alternatives. Each unit dosed at 25 mg.

Key Benefits

• 17α-methylated oral testosterone — first orally-bioavailable androgen
• Used historically for mood elevation and libido restoration
• Aromatises to 17α-methylestradiol — even more potent than native estradiol
• Extreme hepatotoxicity — one of the harshest AAS on the liver
• Rarely used in modern AAS protocols — safer alternatives exist
• Each unit dosed at 25 mg — see Recommended Dosage below for protocol-specific intake

Recommended Dosage

Research / historical dosing: 10–25 mg/day, cycles short (2–4 weeks). Modern AAS protocols generally avoid this compound due to hepatic toxicity and harsh estrogen profile. Never exceed 25 mg/day and never run longer than 4 weeks continuous.

How It Works

17α-methylated testosterone — the methyl group at C17α allows oral bioavailability by resisting first-pass liver metabolism. Aromatises to 17α-methylestradiol, which is pharmacologically more potent than native estradiol — oestrogenic side-effects are severe and not well controlled by standard AIs.

Potential Side Effects

Severe oestrogenic side-effects from potent methylestradiol metabolite (gyno, water retention, mood lability). Massive hepatic burden. Cardiovascular impact significant. HPTA suppression universal. Why safer alternatives exist: modern orals like oxandrolone or turinabol deliver anabolic effect with a fraction of the toxicity.

Cycle & Stacking Guide

Historical / research context only. Modern protocols substitute oxandrolone (cleaner), methandienone (better mass but shorter cycle), or injectable testosterone (no hepatic burden). If used, keep under 4 weeks with aggressive liver support (TUDCA 500 mg/day + NAC 1200 mg/day).

Manufacturer Notes

Astera Labs produces a broad catalogue from research peptides to AAS oils. Lyophilised peptide vials ship with stability documentation.

Storage & Handling

Store upright at 15–25 °C in the original box, protected from light and moisture. Oil-based injectables are shelf-stable for the duration printed on the vial when kept at controlled room temperature. Do not refrigerate — cold thickens the carrier oil and makes drawing/injecting harder. Keep out of reach of children. For research and educational purposes only.
