4X Blend (GHRP-2 / Tesamorelin / MGF / Ipamorelin) (12 mg Vial) Dosage Protocol
4X Blend combines GHRP-2 (5 mg), Tesamorelin (5 mg), MGF (500 mcg), and Ipamorelin (2.5 mg) in a single vial — pairing GHRP, GHRH, and direct muscle-repair signaling.
⚡ Quickstart Highlights
Dosing & Reconstitution Guide
Route: Subcutaneous | Frequency: Once daily (pre-bed typical) | Half-life: Mixed; longest component ~30 min
Standard Approach (3 mL = 4.00 mg/mL)
Reconstituting with 3 mL bacteriostatic water produces a concentration of 4.00 mg/mL. Volume per dose changes with concentration; mg dose itself does not change between vial sizes.
| Phase / Protocol | Dose | U-100 Units | Volume | Doses per vial |
|---|---|---|---|---|
| Standard | 300 mcg | 7.5 units | 0.075 mL | 40 doses |
Reconstitution Steps
- Wipe the vial stopper and BAC water vial with alcohol; let dry.
- Draw 3 mL of bacteriostatic water into a sterile syringe.
- Inject slowly down the inside glass wall of the peptide vial. Do not aim at the powder.
- Gently swirl until fully dissolved. Do not shake.
- Label with reconstitution date. Refrigerate at 2–8°C; use within 28 days.
Supplies Needed
Estimates for an 8-week and 12-week cycle at 300 mcg per dose, once daily (pre-bed typical) (7 doses/week).
| Item | 8-Week Cycle | 12-Week Cycle |
|---|---|---|
| 4X Blend (GHRP-2 / Tesamorelin / MGF / Ipamorelin) (12 mg) vials | 2 vials | 3 vials |
| Insulin syringes (U-100) | 56 | 84 |
| Bacteriostatic water (10 mL) | 1 × 10 mL | 1 × 10 mL |
| Alcohol swabs | 1 × 100-pack | 2 × 100-pack |
Protocol Overview
The 4X Blend stacks four GH-axis peptides — GHRP-2, Tesamorelin, MGF, and Ipamorelin — in a single vial. The combination targets pituitary stimulation (GHRP-2 + Tesamorelin via different receptors), peripheral muscle repair (MGF), and amplification (Ipamorelin). Most research-grade use is once-daily pre-bed.
Dosing Protocol
Daily dosing:
- Standard (300 mcg total, once daily pre-bed): Most common research protocol.
Cycle structure: 8–12 weeks, then 4-week break.
Timing: Pre-bed, fasted, within 1h of sleep.
Storage Instructions
| State | Temperature | Duration |
|---|---|---|
| Lyophilized | −20°C (−4°F) | Up to 24 months, dry & dark |
| Reconstituted | 2–8°C (35–46°F) | Up to 28 days, protect from light |
Important Notes
How This Works
Multi-peptide GH-axis blend combining: GHRP-2 (ghrelin-receptor GH pulse), Tesamorelin (GHRH stimulation), MGF (muscle-specific IGF-1 splice variant for satellite cell activation), and Ipamorelin (clean GH pulse via ghrelin receptor). The four components target overlapping but complementary GH-axis pathways.
Potential Benefits & Side Effects
Potential Benefits
- Multi-pathway GH stimulation in a single injection.
- Combines pituitary stimulation with direct muscle repair signaling.
Side Effect Profile
- Combined side-effect profile of components.
- Injection-site reactions.
- Cortisol/prolactin from GHRP-2.
Lifestyle Factors
- Pre-bed dosing aligns with natural GH pulse.
- Resistance training amplifies muscle-repair effects.
Injection Technique
- Subcutaneous, rotate sites.
