Ipamorelin is the most selective growth hormone secretagogue (GHS) available for research, producing robust GH pulses with minimal cortisol or prolactin elevation. This guide covers practical reconstitution and dosing for research protocols.
What Vials Typically Come In
Ipamorelin research vials are most commonly available in:
- 2 mg vials
- 5 mg vials
- 10 mg vials (for combination protocols)
How to Reconstitute Ipamorelin
Standard reconstitution for a 2 mg vial:
1. Clean rubber stopper with alcohol swab; allow to dry
2. Draw 1–2 mL bacteriostatic water into a syringe
3. Inject water slowly down the vial wall (do not aim at the powder)
4. Swirl gently — do not shake
5. Allow 2 minutes for complete dissolution
Concentration examples:
- 2 mg + 1 mL BW → 2000 mcg/mL
- 2 mg + 2 mL BW → 1000 mcg/mL
- 5 mg + 2 mL BW → 2500 mcg/mL
The 2000 mcg/mL concentration (2 mg in 1 mL) is popular, providing 10–15 injections per vial at standard 100–200 mcg doses.
Standard Research Dosage Ranges
| Protocol | Dose | Frequency |
|---|---|---|
| Standard GH stimulation | 100–200 mcg | 1–3x daily |
| Combined with GHRH analogue | 100–200 mcg | 1–2x daily |
| Maximum GH response | 200–300 mcg | 2–3x daily |
Most referenced research protocol: 200 mcg subcutaneous, once daily at bedtime, often combined with CJC-1295 or sermorelin.
Injection Volume Table
Using a 2000 mcg/mL reconstituted solution (2 mg in 1 mL BW):
| Target Dose | Volume to Inject |
|---|---|
| 100 mcg | 0.05 mL (5 units) |
| 150 mcg | 0.075 mL (7.5 units) |
| 200 mcg | 0.10 mL (10 units) |
| 250 mcg | 0.125 mL (12.5 units) |
| 300 mcg | 0.15 mL (15 units) |

Frequency, Timing, and Cycle Length
- Timing: Bedtime injection is preferred to amplify natural nocturnal GH pulse; pre-workout timing used in some protocols
- Fasting: Best administered fasted or 90+ minutes after the last meal; carbohydrate-rich meals blunt GH response
- Cycle length: Studies up to 12 months; 3–6 months is the most common research duration
- Cycling: Ipamorelin shows minimal receptor desensitization — continuous protocols are used without the "on/off" cycling needed for some GHS compounds
Combination with GHRH Analogues
Ipamorelin is most commonly co-administered with a GHRH analogue:
- CJC-1295 (Mod GRF 1-29) + Ipamorelin: Inject simultaneously at the same site or separate sites
- The combination produces GH pulses 3–5x greater than either alone
Storage
- Lyophilised vials: -20°C
- After reconstitution: 2–8°C; use within 28 days
- Avoid freeze-thaw cycles
