How to Reconstitute Ipamorelin: Step-by-Step Visual Guide

Materials Needed

Gather the following before beginning: lyophilized ipamorelin vial (commonly 2 mg or 5 mg), bacteriostatic water vial (30 mL), U-100 insulin syringes (1 mL, 29–31 gauge), alcohol prep pads, exam gloves, and a sharps container. Ipamorelin is a pentapeptide (5 amino acids) growth hormone secretagogue and selective ghrelin/GHS receptor agonist. Preclinical research has examined its role in growth hormone pulse generation, body composition, and appetite regulation. It is not FDA-approved for human therapeutic use.

Calculating BAC Water Volume

Ipamorelin research doses are typically in the microgram range (100–300 mcg). A practical concentration of 1 mg/mL (1,000 mcg/mL) keeps injection volumes small and dose math simple.

Worked example — 2 mg vial targeting 1 mg/mL: 2 mg ÷ 1 mg/mL = 2 mL BAC water.

Worked example — 5 mg vial targeting 1 mg/mL: 5 mg ÷ 1 mg/mL = 5 mL BAC water. At 1 mg/mL: 100 mcg dose = 10 units on U-100 syringe; 200 mcg = 20 units; 300 mcg = 30 units.

Reconstitution Steps

Step 1 — Swab both vial stoppers with alcohol prep pads. Allow 30 seconds to air-dry.

Step 2 — Draw the calculated BAC water volume into the syringe. For 2 mL, perform two separate 1 mL syringe draws.

Step 3 — Insert the needle into the ipamorelin vial and inject BAC water slowly along the inner glass wall. Ipamorelin is a very small peptide and dissolves readily, but directing fluid at the powder cake can still cause localized degradation.

Step 4 — Gently swirl in slow circular motions until fully dissolved. Ipamorelin dissolves quickly given its small size. Do not shake. Solution should be clear and colorless.

Step 5 — Inspect solution for clarity and absence of particles. Label vial with date and concentration before refrigerating.

Calculating Units on Syringe per Dose

Using 2 mg in 2 mL (1 mg/mL = 1,000 mcg/mL):

100 mcg dose: 100 mcg ÷ 1,000 mcg/mL = 0.1 mL = 10 units on U-100 syringe.

200 mcg dose: 200 mcg ÷ 1,000 mcg/mL = 0.2 mL = 20 units.

300 mcg dose: 300 mcg ÷ 1,000 mcg/mL = 0.3 mL = 30 units.

Storage After Reconstitution

Store reconstituted ipamorelin at 2–8°C. In bacteriostatic water, the solution is generally stable for 4–6 weeks under refrigeration. Ipamorelin is a short, stable peptide; however, avoid freeze-thaw cycles. Keep away from light. Label with reconstitution date and concentration. Lyophilized powder is stable at -20°C for 12–24 months.

Safety Notes and Research Framing

Ipamorelin is a selective growth hormone secretagogue with high GHS-R1a receptor affinity and minimal effect on prolactin and cortisol, distinguishing it from GHRP-2 and GHRP-6. Preclinical research includes body composition, bone density, and GH pulse studies. Ipamorelin is not FDA-approved for human therapeutic use and has not completed Phase III trials.
