Ipamorelin

Ipamorelin is a research peptide that helps the body naturally release growth hormone. It’s designed to work gently without affecting other hormones. It’s studied for recovery, sleep, and muscle support but is not approved for medical use.

Description

• Selective GH secretagogue and GHSR-1a agonist.
• Designed to raise pulsatile GH with minimal prolactin/cortisol effects in models.
• Research-only.

How It Works

• Activates GHSR-1a in hypothalamus/pituitary to trigger endogenous GH pulses.
• Synergy with GHRH analogs (e.g., CJC-1295, Sermorelin).
• Short-acting profile enables time-targeted dosing.

Documented Effects

• Transient GH and downstream IGF-1 rise in preclinical/early human data.
• Supports protein synthesis and recovery markers in models.
• Lower appetite surge relative to some GHRPs.

Theoretical Effects

• GH-axis optimization, recovery, and metabolic studies.
• Outcomes vary by timing and GHRH pairing.

Pharmacokinetics

• Half-life: Roughly 2 hours after subcutaneous injection.
• Time to peak concentration: Around 30–60 minutes post-injection.
• Steady-state: Reached within 24 hours of consistent dosing.

Duration of Effects

• Stimulates GH release for 2–3 hours after dosing.
• Effects on recovery and metabolism may persist for several hours.
• GH pulse returns to baseline by the next dosing window.

Reconstitution

• Use only bacteriostatic water to reconstitute the lyophilized powder.
• Example vial: 10 mg of Ipamorelin
• Choose reconstitution volume based on dosing convenience:
  • 1 mL water → 10 mg/mL → 1 mg per 10 units
  • 2 mL water → 5 mg/mL → 500 mcg per 10 units
• Swirl gently to dissolve; do not shake.
• Refrigerate reconstituted solution (2–8 °C). Use within ~28 days for best stability.

Injectable Dosage Overview (Research Use)

Typical Starting Dose

• 100 mcg SC once daily.
• Conservative entry: 100 mcg pre-sleep.

Common Research Range

• 100–300 mcg per injection, 1–3× daily.
• Often paired with a GHRH analog; morning and/or pre-sleep.

Maximum Research Range

• ~600 mcg per dose or ~900 mcg total daily.
• Diminishing returns at higher exposure.

Standard Cycle Length

• 8–12 weeks on, then similar off period.
• Intermittent schedules preserve responsiveness.

Clinical Notes

• Inject subcutaneously into abdominal or thigh area using insulin syringes.
• Best administered on an empty stomach or before sleep for optimal GH response.
• Can be combined with CJC-1295 (no DAC) or Sermorelin for synergistic GH release.
• Stable for about 28 days when refrigerated (2–8°C). Protect from light and heat. Avoid freezing.

Safety Notes (First-Time Use)

• Possible transient flushing, lightheadedness, mild hunger.
• Research-only; maintain sterile technique and verify purity.
