Injection Guide
A potent growth hormone releasing peptide that signals your pituitary gland to release more GH naturally—think of it as turning up the volume on your body's own growth hormone production.
Route
Subcutaneous
Sites
3 recommended
Frequency
Multiple times daily
Preparation
Bacteriostatic water (BAC water)
Insulin syringe (29-31 gauge, 0.5-1mL)
Alcohol swabs
Sterile GHRP-2 vial (typically 5mg or 10mg)
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
5mg vial + 2.5mL BAC water = 2mg/mL (2000mcg/mL). For 200mcg dose, draw 0.1mL (10 units on insulin syringe).
Dose Calculation
At 2000mcg/mL concentration: 0.05mL (5 units) = 100mcg, 0.1mL (10 units) = 200mcg, 0.15mL (15 units) = 300mcg
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
Clean injection site with alcohol swab and let dry completely
Pinch a fold of skin between thumb and forefinger
Insert needle at 45-90 degree angle into the pinched skin
Inject slowly and steadily
Remove needle and apply light pressure—do not rub the site
Pro Tip
This peptide uses subcutaneous injection into fatty tissue. 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
Morning upon waking, post-workout, and before bed (on empty stomach)
With food?
Must be taken on an empty stomach—wait at least 30-60 minutes before eating. Food significantly blunts the GH release response.
Stacking notes
For maximum effect, combine with a GHRH peptide like CJC-1295 or Sermorelin at the same time. The synergy between GHRP and GHRH can amplify GH release by 5-10x compared to either alone.
Sample Daily Schedule
Morning (upon waking, 6-7 AM)
100-200mcg injection
Site: Abdomen
Inject immediately upon waking on empty stomach. Wait 30-60 minutes before eating breakfast.
Post-workout (or midday if rest day)
100-200mcg injection
Site: Abdomen or thigh
If training, inject post-workout on empty stomach. If rest day, inject 6-8 hours after morning dose.
Before bed (30 minutes prior)
100-200mcg injection
Site: Abdomen
Most important dose for sleep and recovery benefits. Ensure 3+ hours since last meal.
Dosing Tiers
Dose
100 mcg
Frequency
2-3 times daily
Duration
2-4 weeks
Begin here to assess tolerance and response. Best taken on an empty stomach, typically morning and before bed.
Dose
150-200 mcg
Frequency
2-3 times daily
Duration
8-12 weeks
The most commonly used dose range for consistent GH elevation. Inject on empty stomach for best absorption.
Dose
200-300 mcg
Frequency
3 times daily
Duration
8-12 weeks
Maximum dose used by experienced users. Often combined with GHRH for synergistic effects. Monitor for increased side effects.
Preservation
Before Mixing
Store lyophilized (freeze-dried) powder refrigerated at 36-46°F (2-8°C) for several months. Can also be stored frozen at -4°F (-20°C) for longer-term storage up to 24 months. Keep in original packaging away from direct light.
After Mixing
Refrigerate immediately at 36-46°F (2-8°C). Never freeze after reconstitution—this destroys the peptide. Store away from light. Discard after 28 days or if any degradation signs appear.
Shelf Life After Mixing
28 days
Signs of Degradation
Discard the vial immediately if you notice any of these:
Cloudy or milky appearance (should be crystal clear)
Visible particles, floaters, or clumps in solution
Unusual color change from clear/colorless
Solution has been left at room temperature for extended periods
Important
When to Stop
Signs of allergic reaction (rash, swelling, difficulty breathing)
Persistent carpal tunnel symptoms (numbness, tingling, weakness in hands)
Significant blood sugar elevation or difficulty managing diabetes
Pregnancy confirmed or suspected
Development of any new medical condition—consult your provider
Severe or persistent side effects not improving with dose reduction
Always consult with a healthcare provider before stopping or if you experience any concerning symptoms. This information is for educational purposes and should not replace professional medical advice.
Clean Technique Checklist
Wash hands thoroughly with soap and water before handling supplies
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
Store reconstituted peptides according to the storage instructions above
