Ipamorelin Reconstitution Guide: Dosing, Mixing & What to Know

Ipamorelin is one of the most popular growth hormone secretagogue peptides in the research space — and for good reason. It’s the most selective GHRP (growth hormone releasing peptide) available, meaning it stimulates growth hormone release without significantly affecting cortisol, prolactin, or appetite hormones. That selectivity profile is what makes it a favorite among researchers who want GH pulsatility data without the confounding variables that come with less selective secretagogues.

This guide covers everything you need for working with lyophilized ipamorelin: reconstitution, dosing math, storage, and the common CJC-1295 stacking approach.

What Is Ipamorelin?

Ipamorelin is a synthetic pentapeptide (five amino acids: Aib-His-D-2-Nal-D-Phe-Lys-NH₂) that acts as a growth hormone secretagogue. It stimulates the pituitary gland to release growth hormone (GH) by mimicking the action of ghrelin at the GHS-R (growth hormone secretagogue receptor).

What Makes Ipamorelin Different from Other GHRPs

The GHRP family includes several peptides — GHRP-2, GHRP-6, hexarelin — that all stimulate GH release. Ipamorelin stands out because of what it doesn’t do:

This selectivity profile means ipamorelin produces cleaner GH pulses without the side effects (hunger spikes, cortisol elevation, prolactin rise) that complicate research with other GHRPs. It also shows slower receptor desensitization, making it suitable for longer research protocols.

Research Applications

Ipamorelin has been studied in contexts including:

• Growth hormone pulsatility — clean GH release without confounding hormone changes
• Bone density research — GH-mediated effects on bone formation
• Body composition studies — lean mass and fat metabolism
• Post-operative recovery models — GI function and nitrogen balance
• Aging research — age-related GH decline and restoration

How Ipamorelin Is Supplied

Ipamorelin is supplied as a lyophilized white powder in glass vials:

• 5 mg per vial — the standard research size
• 2 mg per vial — occasionally available as trial sizes

Store unreconstituted vials at -20°C for long-term stability. Refrigerator storage (2–8°C) is acceptable for a few months.

How to Reconstitute Ipamorelin

What You’ll Need

• Ipamorelin vial (5 mg example used throughout)
• Bacteriostatic water
• 1 mL insulin syringe for reconstitution
• 0.5 mL or 0.3 mL insulin syringe for dosing
• Alcohol swabs

Choosing Your Water Volume

For a 5 mg vial:

Recommended: 2.5 mL of BAC water for a 5 mg vial. This gives you 2,000 mcg/mL, which puts common doses at round syringe numbers — 10 units for 200 mcg, 15 units for 300 mcg. Clean math reduces dosing errors.

Alternatively, 2 mL works well and keeps the volume slightly more concentrated if you prefer smaller injection volumes.

Step-by-Step Reconstitution

1. Pop off the colored cap from the ipamorelin vial
2. Swab both stoppers with alcohol. Let dry
3. Draw your chosen BAC water volume into the syringe
4. Insert the needle through the stopper, aiming at the vial wall
5. Add water slowly — let it run down the glass over 20–30 seconds
6. Remove the needle and set the vial on a flat surface
7. Swirl gently. Ipamorelin dissolves quickly — usually under 60 seconds
8. Inspect. Solution should be clear and colorless

Ipamorelin is one of the easiest peptides to reconstitute. It dissolves readily and is relatively stable in solution. For full technique details, see our peptide reconstitution guide.

Ipamorelin Dosing

Unlike weekly-dosed peptides like semaglutide, ipamorelin is administered multiple times per day to mimic the natural pulsatile pattern of GH release.

Standard Research Protocol

• Dose per administration: 200–300 mcg
• Frequency: 2–3 times daily
• Timing: Morning, pre-workout (if applicable), and before bed
• Empty stomach preferred: GH release is blunted by elevated blood glucose and insulin; dosing 30+ minutes before or after food is standard protocol

Worked Dosing Example

Setup: 5 mg vial reconstituted with 2.5 mL bacteriostatic water.

Concentration: 5,000 mcg ÷ 2.5 mL = 2,000 mcg/mL

• 200 mcg dose: 200 ÷ 2,000 = 0.1 mL = 10 units
• 300 mcg dose: 300 ÷ 2,000 = 0.15 mL = 15 units

Daily usage at 300 mcg 3x/day: 900 mcg/day = 45 units/day

Vial longevity: 5,000 mcg ÷ 900 mcg/day = 5.5 days per vial at the 3x/day protocol. At 2x/day (200 mcg each), that extends to about 12 days per vial. This is a high-consumption peptide — plan your vial procurement accordingly.

Stacking Ipamorelin with CJC-1295

One of the most common research approaches is stacking ipamorelin with CJC-1295 — a growth hormone releasing hormone (GHRH) analog. The rationale is complementary mechanisms:

• Ipamorelin acts at the GHRP receptor → triggers acute GH pulse
• CJC-1295 acts at the GHRH receptor → amplifies and sustains the GH pulse

Together, they produce a larger and more sustained GH elevation than either alone.

CJC-1295 Variants

• CJC-1295 with DAC (Drug Affinity Complex) — very long half-life (~8 days), creates sustained GH elevation. Dosed 1–2x/week at 1,000–2,000 mcg
• CJC-1295 without DAC (also called Mod GRF 1-29) — shorter half-life (~30 minutes), creates pulsatile GH release. Dosed alongside ipamorelin at 100–200 mcg per injection

When stacking with CJC-1295 without DAC, both peptides are typically drawn into the same syringe and injected together. They’re chemically compatible and can share the same injection.

Storage After Reconstitution

Storage Guidelines

• Reconstituted ipamorelin: Refrigerate at 2–8°C
• Stability window: Up to 28 days after reconstitution
• Never freeze reconstituted solution
• Protect from light — not as critically light-sensitive as Melanotan II, but standard practice
• Unreconstituted powder: -20°C for long-term storage

Given that vials are consumed relatively quickly (5–12 days at typical dosing), the 28-day stability window is usually not the limiting factor. You’ll finish the vial well before expiration in most protocols.

For more on storage best practices, see our peptide storage guide.

Injection Guidance

Ipamorelin is administered via subcutaneous injection.

• Sites: Abdomen, outer thigh
• Needle gauge: 29–31 gauge insulin syringes
• Volume per injection: Small — typically 10–15 units, making injections quick and comfortable
• Timing: On an empty stomach for optimal GH response. Wait 20–30 minutes before eating
• Rotate sites between injections, especially with multiple daily doses

For detailed technique, see our subcutaneous injection guide.

Practical Tips for Ipamorelin Research

Budget for high vial consumption. At 3x/day dosing, you’ll go through a 5 mg vial roughly every 5–6 days. For a 12-week study, that’s approximately 14 vials. Plan procurement accordingly.

Use a 0.3 mL syringe. With dose volumes of 10–15 units, the finer graduations on a 0.3 mL (30-unit) syringe provide better precision than a 1 mL syringe.

Time your doses around food. GH release from ipamorelin is blunted by elevated insulin. The standard approach: dose at least 30 minutes before meals, or 2+ hours after eating. Before-bed dosing on an empty stomach aligns with natural GH secretion patterns.

Don’t rush the titration. While ipamorelin doesn’t have the formal multi-month titration schedule of GLP-1 agonists, starting at 200 mcg for the first few days before moving to 300 mcg helps assess individual response.

Consider the DAC question carefully. CJC-1295 with DAC vs. without DAC fundamentally changes the GH release pattern — sustained elevation vs. pulsatile release. These are different experimental models. Choose based on your research objectives, not convenience.
