GHRP-6 Dosing Protocol: 10 mg Vial — Extended Supply Dosing Guide

High-volume GHRP-6 protocol for the 10 mg vial — the preferred choice for patients on 300 µg 3x daily maximum-output protocols.

Go to peptide profileCalculate your dose

Quickstart highlights

Three daily GHRP-6 injections of 300 µg each generate near-continuous GH somatotroph stimulation.

  • Concentration: 2 mg/mL (10 mg vial + 5 mL bacteriostatic water).
  • At 2 mg/mL: 200 µg = 10 units, 300 µg = 15 units per injection.
  • At 300 µg 3x daily, one 10 mg vial lasts ~11 days; plan 8 vials for a 12-week cycle.
  • The 10 mg vial halves reconstitution frequency versus the 5 mg vial at maximum dosing.
  • Refrigerate; use within 28 days.

Reconstitution steps

  1. Draw 5 mL bacteriostatic water in two separate 2.5 mL draws; inject slowly down the vial wall.
  2. Swirl gently until powder dissolves; do not shake.
  3. Final concentration: 2 mg/mL. Label with date; refrigerate at 2–8 °C. Use within 28 days.

Supplies needed

Protocol overview & cycle notes

Provide maximum GHRP-6 GH pulse frequency support using the efficient 10 mg vial, minimizing reconstitution events for patients optimized on 300 µg 3x daily protocols.

Cycle length: 12 weeks on.

Off-cycle: 4–6 weeks off; measure cortisol and IGF-1 before resuming.

Storage & handling

Lyophilized: store below 25 °C. Reconstituted at 2 mg/mL: refrigerate 2–8 °C; use within 28 days. At 300 µg 3x daily: one 10 mg vial lasts ~11 days; 8 vials needed for 12 weeks.

Injection & tracking tips

  • For high-frequency (3x daily) protocols, schedule injections: morning fasted, 30 minutes pre-workout (fasted), and 30 minutes before bed.
  • Keep a meal ready for 20–30 minutes post-injection to leverage GHRP-6's appetite stimulation for caloric loading.
  • The 10 mg vial offers approximately 50% less handling than the 5 mg vial at the same total dose.

Tracking

Logging helps you and your provider spot patterns and adjust dose or timing.

  • Measure IGF-1 at baseline, 4 weeks, and 8 weeks to optimize timing of any dose adjustments.
  • Track cortisol monthly; GHRP-6 at 300 µg 3x daily may chronically elevate morning cortisol by 20–40%.
  • Log body weight and body fat percentage monthly; GH-mediated lipolysis should produce measurable fat reduction by week 8.

How this works & references

Three daily GHRP-6 injections of 300 µg each generate near-continuous GH somatotroph stimulation. Peak GH concentrations of 4–10 ng/mL occur 15–30 minutes after each injection. Combined with CJC-1295 No DAC (300 µg), peaks reach 15–25 ng/mL per injection event. Total daily GH area-under-the-curve approximates that of therapeutic HGH doses of 2 IU/day.

Frequently asked questions

How do I store the vial between doses during a 3x-daily protocol?
Refrigerate at 2–8 °C between each use. Allow the vial to reach room temperature (5–10 minutes) before drawing each dose. Gently swirl if any visible particles appear; discard if cloudiness persists.
Is 300 µg 3x daily the maximum safe dose?
Based on published literature, 300 µg 3x daily is the practical upper limit for most protocols. Doses above 300 µg per injection do not produce proportionally greater GH release due to somatostatin counter-regulation. The ceiling effect is typically reached at 300 µg per pulse.
Can I add BPC-157 to a GHRP-6 protocol?
Yes — BPC-157 and GHRP-6 address different mechanisms and can be used simultaneously. GHRP-6 targets GH/IGF-1 axis; BPC-157 targets local tissue repair via FAK/VEGFR2/NO pathways. They are typically injected at separate sites or at different times.
What is the IGF-1 expected at 300 µg 3x daily GHRP-6 + CJC-1295?
In responders, combined GHRP-6 (300 µg 3x daily) + CJC-1295 No DAC (300 µg 3x daily) raises IGF-1 by 60–120 ng/mL above baseline over 8–12 weeks. Individual response varies significantly based on age, body composition, and baseline GH reserve.
Should I cycle off GHRP-6 periodically?
Yes — 12 weeks on, 4–6 weeks off is the standard cycle. Downregulation of GHSR-1a receptors with continuous stimulation reduces efficacy over time. Off-cycles restore receptor sensitivity and allow HPA axis normalization if cortisol was elevated.
