Hexarelin Dosing Calculator
Hexarelin: Dual-action GH secretagogue with cardioprotective effects.
Pre-filled with the most-reported community reconstitution protocol for Hexarelin. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.
Quick answer · Community-reported standard
A 5 mg vial of Hexarelin reconstituted with 1 mL of bacteriostatic water yields a concentration of 2.50 mg/mL. At that concentration, a 100 mcg dose of Hexarelin equals 4 units on a U-100 insulin syringe (0.040 mL). Hexarelin is typically administered once daily via subcutaneous.
Hexarelin reconstitution: 1 mL vs 2 mL bac water
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 5 mg vial.
| BAC water added | Concentration | Volume per 100 mcg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 5.00 mg/mL | 0.020 mL | 2 units |
| 2 mL | 2.50 mg/mL | 0.040 mL | 4 units |

Alternative Hexarelin protocols
Beyond the default above, Hexarelin is also reported in the following protocols. Use these as starting points and recalculate with the tool above.
Tolerance Assessment Protocol
Community- Dose
- 100 mcg
- Frequency
- Once daily
- Duration
- First 1-2 weeks
- Route
- Subcutaneous
Starting dose for tolerance assessment before titrating up; used to gauge individual response and side effects
Hexarelin + GHRH Combination
Community- Dose
- 100 mcg hexarelin + 100 mcg Mod GRF 1-29
- Frequency
- 2-3 times daily
- Duration
- 8-12 weeks
- Route
- Subcutaneous
Maximum GH release combination; considered the most potent GHRP + GHRH stack but with most side effects
Cardioprotective Protocol
Community- Dose
- 100-200 mcg
- Frequency
- Once daily
- Duration
- 8-12 weeks
- Route
- Subcutaneous
Lower-dose protocol targeting hexarelin CD36 receptor binding for cardiac health; less focused on GH release
Clinical Trial GH Stimulation Testing
Clinical- Dose
- 1-2 mcg/kg body weight
- Frequency
- Single bolus administration
- Duration
- Acute (single session diagnostic or research use)
Administered intravenously or subcutaneously in Phase 2 clinical trials for GH release assessment
Research GH Secretagogue Protocol
Clinical- Dose
- 100-200 mcg
- Frequency
- 2-3 times daily
- Duration
- Variable; desensitization typically observed within 1-2 weeks of continuous use
Subcutaneous administration; intermittent protocols with rest days may preserve GH response
Hexarelin reconstitution & storage
Reconstitute lyophilized hexarelin with bacteriostatic water for injection. Direct the water stream against the side of the vial, allowing it to gently dissolve the powder without agitation. Do not shake vigorously. Typical reconstitution uses 1-2 mL of bacteriostatic water per vial. Gently swirl if needed until fully dissolved.
Lyophilized powder: Store at -20 degrees Celsius for long-term storage or 2-8 degrees Celsius for short-term storage. Reconstituted solution: Store at 2-8 degrees Celsius (refrigerated), protect from light, and use within 2-4 weeks. Do not freeze reconstituted solution. Avoid repeated freeze-thaw cycles.
Hexarelin dosing FAQ
How much bacteriostatic water should I add to a 5 mg vial of Hexarelin?
The community standard is 1 mL of bacteriostatic water for a 5 mg Hexarelin vial. That gives a concentration of 2.50 mg/mL, so a 100 mcg dose is 4 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 2 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 100 mcg dose of Hexarelin?
On a standard U-100 insulin syringe, a 100 mcg dose of Hexarelin is 4 units when the 5 mg vial is reconstituted with 1 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 2 units (5.00 mg/mL).
What is the standard Hexarelin dose?
Community-reported protocols for Hexarelin typically use 100 mcg–200 mcg once daily via Subcutaneous. 100 mcg is a common starting dose. Most potent common GHRP; requires strict cycling to prevent receptor desensitization. Injected on empty stomach.
How long does a vial of Hexarelin last at 100 mcg once daily?
A 5 mg vial of Hexarelin contains roughly 50 doses at 100 mcg per injection. At once daily dosing, that is approximately 50 days (about 7 weeks) of supply per vial. Reconstituted Hexarelin should generally be used within 28 days when refrigerated.
Where do you inject Hexarelin?
Hexarelin is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdominal region), Subcutaneous (thigh), Intramuscular (clinical research settings), Intravenous (clinical trial settings only). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for Hexarelin?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Hexarelin 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.
