Injection Guide
A powerful synthetic growth hormone secretagogue that tells your pituitary gland to release more growth hormone—plus it has remarkable heart-protective properties that make it stand out from other GH-boosting peptides.
Route
Subcutaneous
Sites
3 recommended
Frequency
Once daily
Preparation
Bacteriostatic water (BAC water)—the preservative keeps it safe for multiple uses
Insulin syringes (29-31 gauge)—thin needles mean less discomfort
Alcohol swabs for cleaning vial tops and injection sites
Your Hexarelin powder vial
Pro Tip
Prepare all supplies on a clean surface before you begin. Having everything ready makes the process smoother and more sterile.
Mixing
Wash your hands thoroughly with soap and water. Gather all supplies on a clean, flat surface.
Remove the plastic cap from the peptide vial and wipe the rubber stopper with an alcohol swab. Let it air dry.
Draw the appropriate amount of bacteriostatic water into a sterile syringe.
Insert the needle into the vial at an angle, aiming at the inside wall of the vial. Slowly push the plunger to let the water trickle down the glass wall -- do NOT squirt directly onto the powder.
Once all water is added, gently swirl the vial in a slow circular motion. Never shake the vial, as this can damage the peptide bonds.
Continue swirling until the powder is completely dissolved and the solution is clear. If particles remain, let the vial sit for a few minutes and swirl again.
Label the vial with the date of reconstitution, the peptide name, and the concentration (e.g. 250mcg per 0.1mL).
Example Calculation
If you have a 5mg vial and add 2.5mL of BAC water, you get a concentration of 2mg/mL (2000mcg/mL). So every 0.05mL (5 units on an insulin syringe) equals 100mcg of Hexarelin.
Dose Calculation
For a 100mcg dose at 2000mcg/mL concentration: draw 0.05mL (5 units on a standard insulin syringe). For 200mcg: draw 0.1mL (10 units).
Pro Tip
Always add the bacteriostatic water slowly, letting it run down the side of the vial. Never shake the vial -- swirl gently to avoid damaging the peptide.
Location
Site 01
Abdomen
Pinch the skin 2 inches from navel. Avoid the area directly around the belly button. Rotate between left and right sides.
Site 02
Outer Thigh
Middle third of the outer thigh. Keep at least 4 inches above the knee and below the hip. Alternate legs each injection.
Site 03
Upper Arm
Back or outer area of the upper arm. This site may require assistance from another person for proper technique.
Rotate between 3 sites to prevent tissue buildup and ensure consistent absorption.
Pro Tip
Rotate your injection sites with each dose to prevent lipohypertrophy (buildup of fatty tissue). Keep a simple log of where you last injected.
Step by Step
Wash your hands thoroughly with soap and water
Clean the injection site with an alcohol swab and let it air dry completely
Pinch about an inch of skin to create a fold
Insert the needle at a 45-90 degree angle (45 if you're lean, 90 if you have more tissue)
Push the plunger slowly and steadily
Wait 5 seconds before removing the needle
Apply light pressure if needed—don't rub
Pro Tip
This peptide uses subcutaneous injection (just under the skin)—the easiest and most common method for self-administration. Inject at a 45-90 degree angle into pinched skin. Aspirate before injecting to ensure you haven't hit a blood vessel.
Timing
Optimal Timing
Best time
On an empty stomach—either first thing in the morning (30-60 minutes before eating) or before bed (2-3 hours after your last meal). The GH pulse is much stronger when you haven't eaten recently.
With food?
Food significantly blunts the GH response. Always inject at least 30 minutes before eating, or 2-3 hours after a meal. Fatty foods especially interfere with absorption.
Stacking notes
Hexarelin pairs well with CJC-1295 (without DAC) or Mod GRF 1-29 for synergistic GH release. If stacking, inject at the same time. Space out from other GHRP peptides to avoid excessive GH spikes or desensitization.
Sample Daily Schedule
Morning (upon waking, before breakfast)
100-200 mcg injection
Site: Rotate between belly, thigh, and arm
Wait at least 30 minutes before eating. Morning dosing takes advantage of your natural cortisol rhythm and won't interfere with sleep.
Evening (before bed, 2-3 hours after dinner)
100-200 mcg injection
Site: Rotate between belly, thigh, and arm
Evening dosing can enhance natural nighttime GH release and may improve sleep quality. Don't eat after injection for best results.
Dosing Tiers
Dose
100 mcg
Frequency
Once daily
Duration
2-4 weeks
Start here to see how your body responds. Hexarelin causes a strong GH pulse, so beginning low helps you gauge tolerance. Take on an empty stomach for best absorption—ideally first thing in the morning or before bed.
Dose
100-200 mcg
Frequency
Once to twice daily
Duration
8-12 weeks
The most commonly used range in research. If dosing twice daily, space injections at least 6 hours apart (morning and evening works well). Always inject on an empty stomach—food blunts the GH response significantly.
Dose
200 mcg
Frequency
Two to three times daily
Duration
8-12 weeks
Higher frequency protocols used in some research settings. Be aware that desensitization can occur with prolonged high-dose use—many users cycle off for 4-8 weeks after 8-12 weeks of use to restore receptor sensitivity.
Preservation
Before Mixing
Keep your Hexarelin powder in the refrigerator (36-46°F / 2-8°C) for short-term storage. For long-term storage (over 2 months), keep in the freezer (-4°F / -20°C). Store in the original sealed vial away from light. Properly stored powder can remain stable for 2+ years when frozen.
After Mixing
Once mixed with bacteriostatic water, refrigerate at 36-46°F (2-8°C). Never freeze the reconstituted solution—freezing destroys the peptide structure. Keep away from light and use within 28-30 days.
Shelf Life After Mixing
28-30 days
Signs of Degradation
Discard the vial immediately if you notice any of these:
Cloudy or hazy appearance (should be crystal clear)
Visible particles floating or settled at the bottom
Color changes—any yellowing or discoloration means toss it
Clumping or gel-like consistency
Important
When to Stop
Any signs of allergic reaction—stop immediately and seek medical help
Severe or worsening water retention that doesn't improve with dose reduction
Persistent numbness or tingling that affects daily activities
Blood sugar issues that don't stabilize
Any side effect that significantly impacts your quality of life
You've completed your planned cycle length
Hexarelin is a research compound, not an FDA-approved medication. Never start, stop, or change your dosing without guidance from a qualified healthcare provider. This information is for educational purposes only—not medical advice.

Swab vial tops and injection site with alcohol and let dry
Never touch the needle tip or allow it to contact non-sterile surfaces
Use a new syringe and needle for each injection
Dispose of used sharps in a proper sharps container
