Quick answer · Community-reported standard
A 10 mg vial of GHRP-6 reconstituted with 1 mL of bacteriostatic water yields a concentration of 5.00 mg/mL. At that concentration, a 100 mcg dose of GHRP-6 equals 2 units on a U-100 insulin syringe (0.020 mL). GHRP-6 is typically administered once daily via subcutaneous.
GHRP-6 10 mg reconstitution and dosage: 1 mL vs 2 mL bac water
For a 10 mg vial of GHRP-6, bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 10 mg vial.
| BAC water added | Concentration | Volume per 100 mcg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 10.00 mg/mL | 0.010 mL | 1 units |
| 2 mL | 5.00 mg/mL | 0.020 mL | 2 units |
GHRP-6 dosage chart: per-injection to weekly total
Common GHRP-6 protocol doses centered on the 100 mcg baseline (research range 100 mcg–200 mcg), with weekly totals at once daily frequency.
| Dose level | Per injection | Frequency | Weekly total |
|---|---|---|---|
| Lower | 0.05 mg | Once daily | 0.35 mg |
| Baseline | 0.1 mg | Once daily | 0.7 mg |
| Higher | 0.15 mg | Once daily | 1.05 mg |
| Upper range | 0.2 mg | Once daily | 1.4 mg |
Weekly totals assume consistent once daily dosing. Adjust the calculator below for your specific vial size and dose.

Subcutaneous injection; GH peak at 15-30 minutes
GHRP-6 reconstitution & storage
Lyophilized GHRP-6 is typically reconstituted with bacteriostatic water or sterile water for injection. Research-grade vials (commonly 5 mg) are reconstituted to desired concentration. Gentle swirling rather than vigorous shaking is recommended.
Lyophilized GHRP-6 should be stored at -20 degrees C or below for long-term storage. Reconstituted solutions should be refrigerated at 2-8 degrees C and used within 2-4 weeks. Protect from light and repeated freeze-thaw cycles.
GHRP-6 dosing FAQ
How much bacteriostatic water should I add to a 10 mg vial of GHRP-6?
The community standard is 1 mL of bacteriostatic water for a 10 mg GHRP-6 vial. That gives a concentration of 5.00 mg/mL, so a 100 mcg dose is 2 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 10.00 mg/mL and halves the draw to 1 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 100 mcg dose of GHRP-6?
On a standard U-100 insulin syringe, a 100 mcg dose of GHRP-6 is 2 units when the 10 mg vial is reconstituted with 1 mL of bacteriostatic water (5.00 mg/mL). If you use 1 mL of bac water instead, draw 1 units (10.00 mg/mL).
What is the standard GHRP-6 dose?
Community-reported protocols for GHRP-6 typically use 100 mcg–200 mcg once daily via Subcutaneous. 100 mcg is a common starting dose. Injected on empty stomach; produces strong GH release with significant appetite increase within 20-30 minutes
How long does a vial of GHRP-6 last at 100 mcg once daily?
A 10 mg vial of GHRP-6 contains roughly 100 doses at 100 mcg per injection. At once daily dosing, that is approximately 100 days (about 14 weeks) of supply per vial. Reconstituted GHRP-6 should generally be used within 28 days when refrigerated.
Where do you inject GHRP-6?
GHRP-6 is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdomen, deltoid region), Intravenous (clinical research settings), Intranasal (research, lower bioavailability). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for GHRP-6?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like GHRP-6 because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
