How to Reconstitute & Inject
Use bacteriostatic (BAC) water only. Avoid saline — may cause precipitation. Refrigerate and use within 28 days.
1
Remove Mod GRF 1-29 vial from refrigeration and allow to reach room temperature (15–20 minutes) 2
Clean vial top with alcohol swab and allow to air dry completely 3
Using a sterile syringe, draw the calculated volume of bacteriostatic water (BAC water) 4
Inject BAC water slowly down the side of the vial — do not aim directly at the powder 5
Gently swirl in circular motions — DO NOT shake vigorously as this degrades the peptide 6
Allow 2–3 minutes for full dissolution — solution should be clear and colorless 7
Draw calculated dose into an insulin syringe for subcutaneous injection 8
Inject into abdomen, thigh, or upper arm. Rotate injection sites to prevent lipodystrophy 9
Store reconstituted solution refrigerated (2–8°C) and use within 28 days
What to Expect
Week 1–2
Improved sleep quality may begin. Mild water retention possible initially.
Week 2–4
Deeper sleep, improved recovery. Appetite may increase slightly.
Week 4–8
Noticeable improvements in body composition, energy, and recovery speed.
Week 8–12
Skin quality improvements, reduced body fat, increased lean mass becoming visible.
Week 12+
Sustained improvements in body composition, strength, and overall vitality.
Side Effects & Safety
Water retention and mild bloating, especially early in protocol Increased appetite (particularly with GHRP compounds) Flushing or warmth at injection site Tingling or numbness (carpal tunnel-like symptoms at higher doses) Fatigue or lethargy if dosed at suboptimal times Cortisol and prolactin elevation possible (especially GHRP-6) Rare: Elevated blood glucose — monitor if diabetic or pre-diabetic
