What is Hexarelin?
Hexarelin is one of the strongest peptides available for triggering natural growth hormone release, working through the same pathway as the 'hunger hormone' ghrelin. Beyond its effect on growth hormone, it also appears to have a direct protective effect on heart tissue. It has been tested in human trials for growth disorders in children and is widely studied for hormone optimization, heart protection, and body composition.

How Does Hexarelin Work?
It binds the same 'hunger hormone' receptor as ghrelin, triggering a strong pulse of growth hormone release from the pituitary. It also attaches separately to a receptor found in heart tissue, giving it a protective effect on the heart that's unrelated to its growth hormone activity.
Mimics ghrelin
Binds the same receptor as ghrelin to trigger growth hormone release.
Strong pulse
Produces a particularly strong pulse of growth hormone from the pituitary.
Protects the heart
Separately binds a heart-tissue receptor for an unrelated protective effect.

How to reconstitute Hexarelin
The materials you'll need and step-by-step instructions for safely mixing Hexarelin with bacteriostatic water.
Materials needed
Your Hexarelin vial (lyophilized)
Alcohol swabs
Bacteriostatic sterile water
3 mL syringes (Luer Lock tip)
25G or 27G needles (Luer Lock). Other gauges may also be acceptable.
Sharps container (optional)
Remove the caps
Sanitize the rubber stoppers
Attach the needle
Draw the bac water
Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.
Insert the needle into the Hexarelin vial
With the bac water in your syringe, insert the needle into the Hexarelin vial at a slight angle to avoid pressure buildup.
Release the water gently
Let the water run gently down the side of the vial. Don't inject it forcefully.
Swirl to dissolve
Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.
Check for full dissolution
Cap, dispose, and store
How to Store Hexarelin
Keep the dry powder well below freezing, dry and away from light; it can handle room temperature for 3–4 weeks. Once mixed with liquid, refrigerate and use within 10–14 days, avoiding repeated freezing and thawing.
Lyophilized Storage
Store below -18°C, desiccated, away from light; stable at room temperature for 3–4 weeks.
Reconstituted Storage
Refrigerate at 2–8°C, use within 10–14 days.
Handling Notes
Avoid repeated freeze-thaw cycles.
What Are the Benefits of Hexarelin?
What research says it may help with, and how it works in the body.
growth hormone enhancement
The strongest peptide of its kind for triggering the body's own growth hormone release from the pituitary gland.
When combined with another growth-hormone-releasing peptide (GHRH), it boosts growth hormone release by more than the two would achieve separately.
Meaningfully raises IGF-1 levels by boosting the release of growth hormone.
cardiovascular
Protects heart tissue by activating a specific docking site on cells called the CD36 receptor.
Affects the heart by increasing the flow of calcium into heart cells through channels that open in response to electrical signals.
Reduces the programmed death of heart muscle cells and helps regulate the electrical signals that drive each heartbeat.
metabolic
Improves how the body processes fats, acting through the CD36 receptor, in lean animal models with insulin resistance.
Improves the ratio of lean muscle to body fat by raising growth hormone and IGF-1 levels.
What Are the Side Effects of Hexarelin?
Who should avoid it, warning signs to watch for, and what to know before combining it with other compounds.
Who Should Avoid It
Active cancer or history of cancer
Pregnancy or breastfeeding
Pituitary disorders
WADA prohibited for competitive athletes
Stop Right Away If You Notice
Severe or persistent headaches
Unusual swelling
Signs of carpal tunnel syndrome
Allergic reactions
Milder Signs to Watch For
How Long Should a Hexarelin Cycle Last?
This breaks down how long a typical Hexarelin cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.
That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.

Frequently Asked Questions About Hexarelin
Straight answers on reconstitution, dosing, and safety, everything you need to research with confidence. For research reference only.
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 syringe units 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.
Are peptides safe?
There is no single answer because every peptide is entirely different. Safety depends on the specific compound, how pure it is, the dose you take, the way it was made, and your own personal medical history.
Are all peptides medicines?
No, they are not all medicines. The word "peptide" just describes the shape and chemical makeup of the molecule, rather than its legal or medical status. While some are officially approved prescription drugs, many others are strictly for research or are used as standard health supplements.
What does peptide reconstitution mean?
Reconstitution is the simple process of mixing a freeze-dried powder with a safe liquid to turn it into a usable liquid solution. Whenever this is done, it requires very clean and sterile methods to prevent any harmful bacteria from getting into the mixture.
Which peptide is best for my goals?
There is rarely one single best option for everyone. Instead of looking for a magic compound, it is much safer and more effective to start by looking at your specific goals. We recommend exploring our category pages first to learn about the different options that align with what you want to achieve.
