Description
Boldenone Undecylenate 250 mg Somatrop-Lab — boldenone undecylenate from Somatrop-Lab at 250 mg. The 14-day half-life is among the longest of any injectable steroid — expect 6–8 weeks for full onset, and plan cycle length (14–20 weeks) accordingly.
Key Benefits
- Slow, steady lean-mass accrual — the patient lifter’s compound
- Increased RBC production and vascularity
- Mild oestrogenic conversion — AI usually sufficient at low dose
- Appetite enhancement supports off-season caloric surpluses
- Minimal androgenic sides at typical performance doses
- Each unit dosed at 250 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 400–600 mg/week. Often front-loaded at 800 mg week 1 to speed up saturation (long ester takes 5+ weeks otherwise). Cycles 14–20 weeks. Above 800 mg/week lipid and BP effects grow without proportional gain.
How It Works
Dihydrotestosterone with a 1,2-double bond — structurally close to methandienone but without the 17α-methyl group, so no oral bioavailability and no hepatotoxicity. Converts weakly to estradiol (~half the rate of testosterone). Also metabolises to a hydroxylated form that can act as a mild AI itself.
Pharmacokinetics
Undecylenate ester. Plasma half-life approximately 14 days. Steady-state at 4–5 weeks without front-load; 2 weeks with. Weekly or bi-weekly pinning fine. Long clearance — PCT at week 3 post-last-injection.
Cycle & Stacking Guide
Long lean-gain cycles 16–20 weeks. Classic pairing: test E 400 mg/week + EQ 600 mg/week + (optional) winstrol or anavar for final 6 weeks. Not a first-cycle compound — long duration demands disciplined bloodwork and diet.
Manufacturer Notes
Somatrop-Lab specialises in growth-hormone and peptide products with lyophilised format and strict cold-chain 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.
