Type
Hexarelin is one of the most potent synthetic growth hormone secretagogues available. It stimulates GH release by binding to the GHS-R1a receptor in the pituitary and hypothalamus, mimicking the action of ghrelin. Notably, Hexarelin demonstrates synergistic effects when combined with GHRH, producing GH responses greater than the arithmetic sum of either peptide alone. It also shows unique cardioprotective properties mediated through the CD36 receptor.

Overview of Hexarelin
Hexarelin binds to the growth hormone secretagogue receptor 1a (GHS-R1a) in the brain and pituitary gland. This binding initiates a signaling cascade that stimulates somatotroph cells in the anterior pituitary to produce and release growth hormone. Hexarelin also has slight, dose-dependent effects on prolactin, ACTH, and cortisol release. Its cardioprotective effects are mediated through CD36 receptor activation and modulation of calcium channels in cardiomyocytes.

- Most potent GHRP for stimulating endogenous growth hormone release from the pituitary.
- Produces synergistic GH release when combined with GHRH, greater than sum of individual effects.
- Significant increases in IGF-1 levels through enhanced GH secretion.
cardiovascular
- Protective effects on cardiac tissue mediated through CD36 receptor activation.
- Reduces apoptosis of cardiomyocytes and controls cardiac action potential.
- Cardiotropic effects mediated by elevation of Ca2+ influx through voltage-gated calcium channels.
metabolic
- Beneficial effects on lipid metabolism via CD36 receptor in non-obese insulin-resistant models.
- Improved lean mass to fat ratio through GH and IGF-1 elevation.

Reconstitution Instructions
Materials needed:
Steps to reconstitute
- Clean work area and hands thoroughly
- Calculate required BAC water volume
- Draw BAC water into syringe
- Inject slowly down vial side (not directly onto powder)
- Gently swirl until dissolved (never shake)
- Store in refrigerator, use within 28 days
Hexarelin Cycle
The Hexarelin Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.
- Week 0-0
- GH spike within 15-30 minutes of injection
- Week 1-2
- Improved sleep quality and recovery
- Week 2-4
- Enhanced energy and well-being
- Week 4-8
- Noticeable improvements in body composition
- Week 8-12
- Maximum benefits; consider cycling to prevent desensitization

Reconstitution Tips
- Use bacteriostatic water (BAC) — contains 0.9% benzyl alcohol for preservation
- Inject water slowly — aim down the vial wall, not directly onto powder
- Never shake — gently swirl or roll the vial until dissolved
- Store properly — refrigerate at 2-8°C after reconstitution
- Use within 28 days — most reconstituted peptides remain stable for about 4 weeks
- Keep sterile — always clean vial tops with alcohol before drawing

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
