Mixing it, step by step

Step by step

Reconstitution steps

Every step below uses the numbers you entered above.

  1. 1
    Wipe both stoppers

    Swab the rubber tops of the 10 mg Hexarelin vial and the bacteriostatic water vial with fresh alcohol pads. Let them air dry for a few seconds.

  2. 2
    Draw 4 mL of BAC water

    Pull 4 mL of bacteriostatic water into a reconstitution syringe (usually a 3 mL syringe with a 21g needle).

  3. 3
    Add water slowly, down the side

    Inject the water against the inside wall of the vial, don't blast it directly onto the powder. This protects the peptide from shear damage.

  4. 4
    Swirl, don't shake

    Gently swirl until the powder is fully dissolved and the liquid is clear. Never shake, foaming denatures the peptide.

  5. 5
    Draw 4 units on a 1 mL syringe

    On your 100-unit (1 mL) insulin syringe, pull the plunger back until the rubber tip lines up with 4, that's your 100 mcg dose. Tap out any air bubbles, then inject as directed.

  6. 6
    Store refrigerated

    Cap the vial and store at 2–8 °C (36–46 °F). Most reconstituted peptides remain stable for 3–4 weeks refrigerated.

What to expect, week by week

Week 1

Deeper sleep, vivid dreams, possible morning hand tingling — normal GH-axis signals.

Weeks 2–4

Recovery between sessions improves. Modest fullness in muscles from mild water retention.

Weeks 4–8

Body comp changes become visible. Fat drops slightly, muscle looks fuller. Bloodwork check recommended.

Weeks 8+

Cycle off for at least equal time to restore natural pulsatility. Track IGF-1 if running longer.

Side effects to watch

  • Hunger spikes
  • Mild cortisol bump
  • Prolactin elevation at high doses

Why people run it

  • Largest GH pulse of the GHRPs
  • Cardio protective signaling
  • Strong recovery effect
