How to Reconstitute Ipamorelin: Step-by-Step Guide (2026)
Ipamorelin reconstitution guide: 2mL BAC water into a 5mg vial = 10 units per 250mcg dose. Dilution charts, timing, and storage tips.
How to Reconstitute Ipamorelin
Ipamorelin is a growth hormone secretagogue — it signals your pituitary gland to release growth hormone in a pulsatile, natural pattern. It arrives as a lyophilized powder and needs to be mixed with bacteriostatic water before use.
The reconstitution process is the same as any peptide, but Ipamorelin has a few practical considerations around dose precision and timing that matter more than with healing peptides.
What You Need
Before you start, gather everything:
- Ipamorelin lyophilized vial (typically 2mg or 5mg)
- Bacteriostatic water (BAC water) — not sterile water, not saline
- Insulin syringes — 1mL (100 unit), 29-31 gauge
- Alcohol swabs — for cleaning vial tops
- A clean, flat workspace
Why bacteriostatic water? It contains 0.9% benzyl alcohol that prevents bacteria from growing in your solution. Regular sterile water has no preservative, so the vial must be used within 24 hours. BAC water gives you up to 28 days refrigerated.
Step-by-Step Reconstitution
Step 1: Clean Everything
Wipe the tops of both vials (Ipamorelin and BAC water) with alcohol swabs. Let them air dry for 10 seconds. This prevents contamination — skip it at your own risk.
Step 2: Draw Your Bacteriostatic Water
Using a fresh insulin syringe, draw your desired amount of BAC water. The amount you add determines your concentration (see the dilution charts below).
For a 5mg vial, 2mL is the sweet spot. It gives clean numbers for standard 200-300mcg doses.
Step 3: Add Water to the Peptide Vial
Insert the needle into the Ipamorelin vial at an angle, aiming at the glass wall — not directly at the powder. Let the water trickle down the side of the vial gently.
Do not squirt water directly onto the powder. Peptides are fragile. Aggressive mixing can damage the molecular structure and reduce potency.
Step 4: Let It Dissolve
Gently swirl the vial with a slow rotating motion. Do not shake it. The powder should dissolve within 1-2 minutes into a perfectly clear, colorless solution.
If particles remain after 5 minutes of gentle swirling, the peptide may be degraded. A properly manufactured Ipamorelin dissolves easily.
Step 5: Store Correctly
Refrigerate immediately at 36-46F (2-8C). The reconstituted solution is stable for up to 28 days with bacteriostatic water.
Dilution Charts
2mg Vial
| BAC Water Added | Concentration | 200mcg Dose | 300mcg Dose |
|---|---|---|---|
| 1mL | 2,000mcg/mL | 10 units (0.1mL) | 15 units (0.15mL) |
| 2mLRecommended | 1,000mcg/mL | 20 units (0.2mL) | 30 units (0.3mL) |
5mg Vial
| BAC Water Added | Concentration | 200mcg Dose | 300mcg Dose |
|---|---|---|---|
| 1mL | 5,000mcg/mL | 4 units (0.04mL) | 6 units (0.06mL) |
| 2mLRecommended | 2,500mcg/mL | 8 units (0.08mL) | 12 units (0.12mL) |
| 2.5mL | 2,000mcg/mL | 10 units (0.1mL) | 15 units (0.15mL) |
Why 2mL? It gives you clean, round numbers for standard doses — easy to measure, hard to mess up.
The Math (So You Can Do It Yourself)
Here's the formula for any vial size and any amount of water:
Concentration = Peptide Amount (mcg) / Water Added (mL)
Then to find your injection volume:
Units to inject = Desired Dose (mcg) / Concentration (mcg/mL) x 100
Example: 5,000mcg vial + 2mL water = 2,500mcg/mL. For a 300mcg dose: 300 / 2,500 x 100 = 12 units.

Common Mistakes
Shaking the Vial
Peptides are proteins. Shaking creates foam, which means air bubbles trapped against peptide molecules. This can denature (destroy) the peptide at the air-liquid interface. Always swirl gently.
Using Too Little Water
Adding 0.5mL to a 2mg vial gives you 4,000mcg/mL. A 200mcg dose is only 5 units — hard to measure precisely. With a 5mg vial at 0.5mL, it's even worse. Use at least 1mL, ideally 2mL.
Leaving It at Room Temperature
Reconstituted Ipamorelin degrades rapidly above refrigerator temperature. Every hour at room temperature reduces potency. Pull the vial out, draw your dose, put it back. Don't leave it on the counter while you prep.
Reusing Needles
Each puncture through the rubber stopper dulls the needle and increases contamination risk. Fresh syringe every time — they cost pennies.
Freezing Reconstituted Peptide
Freezing a liquid peptide solution creates ice crystals that can shear the peptide bonds apart. Only freeze lyophilized (powder) peptides. Once reconstituted, refrigerate — never freeze.
Eating Too Soon After Injection
This isn't a reconstitution mistake, but it's the most common dosing error with Ipamorelin. Food — especially carbohydrates and fats — blunts the growth hormone pulse. Wait at least 30 minutes after injection before eating, and avoid eating for 2 hours before injection for maximum effect.
How Many Doses Per Vial?
This depends on your dose and vial size:
2mg vial at 200mcg/dose = 10 doses 2mg vial at 300mcg/dose = 6.6 doses (approximately 6) 5mg vial at 200mcg/dose = 25 doses 5mg vial at 300mcg/dose = 16.6 doses (approximately 16)
At a standard protocol of 200-300mcg once or twice daily, a 5mg vial lasts 8-25 days depending on frequency and dose. A 2mg vial goes fast — most people prefer 5mg vials for cost efficiency.
Storage Quick Reference
| State | Temperature | Shelf Life |
|---|---|---|
| Lyophilized (powder) | Room temp | 6-12 months |
| Lyophilized (powder) | Refrigerated | 2+ years |
| Lyophilized (powder) | Frozen (-20C) | 3+ years |
| Reconstituted (BAC water) | Refrigerated | Up to 28 days |
| Reconstituted (sterile water) | Refrigerated | Use within 24 hours |
Pro tip: If you buy multiple vials, keep unopened ones in the freezer and only reconstitute what you'll use within 3-4 weeks.
