Injection Guide
A synthetic hexapeptide that signals your pituitary to release growth hormone through a unique pathway, with emerging evidence of heart-protective benefits.
Route
Subcutaneous
Sites
4 recommended
Frequency
Multiple times daily
Preparation
Sterile bacteriostatic water (0.9% sodium chloride saline or bacteriostatic water with benzyl alcohol)
Insulin syringe (29-gauge or similar for drawing and injecting)
Sterile alcohol pads or swabs for cleaning vials
GHRP-6 lyophilized peptide vial
Sterile needle or pin for creating air passage into vial during reconstitution
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 want a concentration of 100 mcg/mL: Reconstitute with 50mL of bacteriostatic water (5,000 mcg ÷ 100 mcg/mL = 50mL). Each 0.1mL drawn equals 10 mcg, and each full 1mL syringe mark equals 100 mcg.
Dose Calculation
To find your dose volume: (Desired dose in mcg ÷ Concentration per mL) × 1mL = Volume to inject. Example: For a 100 mcg dose from a 100 mcg/mL solution, draw 0.1mL (or 10 units on an insulin syringe).
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.
Site 04
Gluteal
Upper outer quadrant of the buttock. This site is best for intramuscular injections and larger volumes.
Rotate between 4 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, then clean the injection site with an alcohol pad, moving outward from the center in a circular motion. Let it air dry completely (alcohol stings otherwise).
Hold the syringe like a pencil at a 45-degree angle to your skin, or perpendicular (90 degrees) if you prefer a quicker jab. Both work fine for subcutaneous injection.
Pinch the skin at the injection site to create a small fold, then quickly insert the needle through the skin into the subcutaneous tissue. You'll feel a slight give as the needle enters.
Once the needle is in, release the pinched skin and slowly push the plunger to inject the peptide. Go slowly to minimize discomfort and give the peptide time to disperse.
Withdraw the needle, massage the site gently for 5-10 seconds to distribute the liquid, and apply gentle pressure with a clean alcohol pad. Rotate injection sites daily to prevent lipohypertrophy (hardened lumps from repeated injections in the same spot).
Pro Tip
This peptide uses subcutaneous injection (under the skin, not into muscle) is standard and most comfortable. intravenous administration is reserved for clinical and research settings.. 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
Many users prefer evening and morning injections to align with natural GH release patterns. Morning injections can support daytime recovery and appetite, while evening injections work with the body's natural nighttime GH surge. Timing around intense workouts can amplify results, as GH stimulus compounds with exercise-induced GH elevation.
With food?
GHRP-6 works best on an empty stomach or at least 30-60 minutes before eating, as food can blunt the GH response. However, its hunger-stimulating effects mean you'll likely want to eat soon after. Consider timing injections before planned meals so the appetite stimulation works in your favor.
Stacking notes
If combining with other peptides like CJC-1295 or Ipamorelin, space injections 10-15 minutes apart or use separate injection sites to avoid mixing. GHRP-6's short half-life (~2.5 hours) means multiple daily doses are needed to maintain elevated GH levels. Some advanced users employ a 5-days-on, 2-days-off protocol to prevent receptor downregulation.
Sample Daily Schedule
Morning (7-8 AM)
100-150 mcg injection
Site: Abdomen or outer thigh (rotate daily)
Morning injection capitalizes on the body's natural morning cortisol and GH patterns. Expect appetite stimulation within 15-30 minutes, making this a good time to prepare breakfast. This injection sets a positive tone for daily energy and recovery.
Afternoon/Pre-workout (12-2 PM)
100-150 mcg injection
Site: Upper arm or opposite thigh from morning
If training in late afternoon, inject 30-60 minutes before for synergistic GH elevation. Alternatively, inject around lunchtime for sustained midday appetite and energy. This second daily injection maintains elevated GH throughout active hours.
Evening (6-8 PM)
100-150 mcg injection
Site: Glutes or alternate abdomen side
Evening injection aligns with the body's natural evening GH surge and supports nighttime recovery. Inject at least 2-3 hours before bed to avoid excessive hunger disrupting sleep. This final daily dose ensures sustained GH elevation into the recovery period.
Dosing Tiers
Dose
100 mcg per injection
Frequency
1-2 times daily (morning and/or evening)
Duration
2-4 weeks
Begin with once-daily dosing to assess tolerance and individual response. Many users start with an evening injection to take advantage of natural nighttime GH pulses.
Dose
150-200 mcg per injection
Frequency
2-3 times daily (morning, afternoon, evening)
Duration
6-8 weeks
Most users find this range effective for sustained GH stimulation. Timing around workouts can maximize the anabolic response. Some space injections 4-6 hours apart.
Dose
250-300 mcg per injection
Frequency
3+ times daily
Duration
8-12 weeks
Only for experienced users with good tolerance established. Higher frequency can lead to receptor desensitization, so cycling (e.g., 5 days on, 2 days off) may preserve effectiveness. Requires careful monitoring.
Preservation
Before Mixing
Store the lyophilized GHRP-6 vial in a cool, dry place below 25°C (77°F). Refrigeration at 2-8°C (36-46°F) is ideal and extends shelf life. Keep away from direct sunlight, humidity, and heat sources like radiators. A sealed container protects from moisture.
After Mixing
Once mixed with bacteriostatic water, store in the refrigerator at 2-8°C (36-46°F). Keep the vial sealed and upright. Protect from light by storing in a dark container or keeping the vial in its original box. Properly stored reconstituted GHRP-6 remains stable for 7-14 days.
Shelf Life After Mixing
Typically 7-14 days when stored properly in the refrigerator, though exact stability depends on your reconstitution solution. Always check for visible changes before use.
Signs of Degradation
Discard the vial immediately if you notice any of these:
Visible discoloration, cloudiness, or particulates in the solution (should be clear and colorless)
Change in smell—any unusual or off odor indicates contamination or degradation
Separation or crystallization of the solution (looks grainy or has settled solids)
The vial cap or seal appears damaged, cracked, or shows signs of tampering
Important
When to Stop
Severe allergic reaction or anaphylaxis—discontinue immediately and seek emergency care
Persistent chest pain, severe cardiac symptoms, or arrhythmias—stop and consult cardiology
Signs of severe carpal tunnel syndrome or nerve compression worsening significantly
Inability to tolerate side effects despite dose reduction (severe headaches, dizziness, joint pain)
Blood pressure elevation that doesn't respond to standard management or dietary modification
Completing your planned 8-12 week cycle—take a break before considering another round to prevent receptor desensitization
