Sustanon 250mg

Description

Sustanon 250mg — four-ester testosterone blend from the manufacturer 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.

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.

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.
