Description
This Astera Labs trenbolone acetate at 150 mg delivers the fastest trenbolone ester available. Effects noticeable within 48 hours; clearance quick if side-effects (trensomnia, night sweats) require withdrawal. Not a beginner compound — testosterone base required.
Key Benefits
- Trenbolone — potent AR agonist, no aromatisation, progestagenic
- Nutrient-partitioning benefit on any ester form
- Dose and injection frequency depend on specific ester
- Side-effect burden same across esters — not softer in any form
- Cabergoline for prolactin, bloodwork mid-cycle mandatory
- Each unit dosed at 150 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing depends on ester: acetate 50–100 mg EOD; enanthate 200–400 mg/week split; hex 100–200 mg/week. Cycle length 8–14 weeks by ester.
How It Works
19-nor derivative. Extreme AR affinity (~5× testosterone). Does not aromatise. Progestagenic. Potent nutrient-partitioner.
Pharmacokinetics
Ester-dependent: acetate ~1 day half-life; enanthate ~7 days; hexahydrobenzylcarbonate ~10 days. Pinning frequency by ester.
Potential Side Effects
Night sweats, insomnia, aggression, CV stress, prolactin rise. Caber 0.25 mg 2×/week. Monitor BP and HDL throughout.
Cycle & Stacking Guide
Cutting and recomp. Pair with a testosterone base at 1:1 or 1.5:1 ratio. Not for first or second cycles.
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.
