Sustanon 250 mg Somatrop-Lab

Description

Sustanon 250 mg Somatrop-Lab — four-ester testosterone blend from Somatrop-Lab at 250 mg. Propionate peaks within 24 h, phenylpropionate at 1–2 days, isocaproate at 4–5 days, decanoate at 7–9 days. Designed to minimise injection frequency: once or twice weekly is sufficient for most protocols.

Concentration: 250 mg per unit. Consistent dosing verified through rigorous quality control and GMP-certified manufacturing.

Key Benefits

• Multi-ester blend — acute kick + long-tail coverage from one injection
• Classic Sustanon / Omnadren formulation (prop + phenyl + iso + deca)
• Twice-weekly pinning schedule covers all four ester kinetics
• Behaves functionally like testosterone enanthate for cycle planning
• Popular pharma-grade option where single-ester vials aren’t available
• Each unit dosed at 250 mg — see Recommended Dosage below for protocol-specific intake

Recommended Dosage

Research dosing: 250–750 mg/week; TRT 100–200 mg/week. Split across at least 2 injections (Mon/Thu). Shorter esters in the blend push injection frequency — once-weekly produces noticeable troughs.

How It Works

Mixture of 4 testosterone esters: propionate (fast), phenylpropionate (short-medium), isocaproate (medium), decanoate (long). At the AR the active hormone is identical across esters; the blend provides staggered release kinetics for smoother coverage.

Pharmacokinetics

Composite release: propionate peaks in ~24 h, phenylpropionate ~2 days, isocaproate ~3–4 days, decanoate ~7–10 days. Net effect similar to enanthate but with a gentler peak. Steady-state in 4 weeks. PCT starts 2 weeks after last injection.

Potential Side Effects

Standard testosterone side-effect profile. Propionate fraction can cause PIP; some users prefer pure enanthate for tolerability. AI dose by bloodwork — hematocrit and E2 at week 6.

Cycle & Stacking Guide

Cycle base identical to enanthate: 12–16 weeks for mass/recomp, paired with secondary compounds per goal. Twice-weekly pinning mandatory. PCT (Clomid + Nolva) 14 days after last pin.

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.
