Description

Testosterone Suspension 50 mg GM Pharmaceuticals — Testosterone Suspension — unesterified aqueous testosterone. Instant activity, hours-long half-life; daily pinning. Each unit dosed at 50 mg.

Key Benefits

  • Unesterified aqueous testosterone — instant activity, no ester conversion
  • Shortest half-life of any testosterone form — hours not days
  • Common pre-workout compound at strength-focused gyms
  • PIP significant — aqueous suspension irritates tissue
  • Best for single-day use events, rarely for long protocols
  • Each unit dosed at 50 mg — see Recommended Dosage below for protocol-specific intake

Recommended Dosage

Research dosing: 50–100 mg daily or pre-workout. Not a long-cycle compound — used as an acute pre-training add-on or for powerlifting meets. Cycles combining suspension with long-ester base are common (suspension for the peak, enanthate for the base).

How It Works

Free testosterone in aqueous carrier (micro-crystalline suspension). No ester means no conversion step — full androgenic activity begins within 30 minutes of injection. Same receptor action as esterified testosterone.

Pharmacokinetics

Plasma half-life approximately 12–24 hours. Rapid onset, rapid clearance. Daily pinning required for sustained effect; even EOD creates measurable troughs. PCT timing identical to propionate (3–5 days post-last-dose).

Potential Side Effects

PIP substantial — the aqueous carrier irritates tissue more than oil-based esters. Oestrogenic side-effects develop fast due to rapid conversion. Same cardiovascular and HPTA profile as other testosterone forms but compressed in time.

Cycle & Stacking Guide

Pre-workout add-on to a long-ester base, or short (2–4 week) strength peak protocols. Not for lean-mass runs — the ester-less kinetics make E2 control harder than weekly enanthate.

Manufacturer Notes

GM Pharmaceuticals is an independent producer in the research-compound market. Before first use, request the batch-specific Certificate of Analysis and confirm the vial’s tamper-evident seal is intact.

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.
