Muscle Gain Stack

The most established growth-stimulation protocol in the research literature: a GHRH and a GHRP, paired to amplify one and the same signal.

Why this combination

The GHRP + GHRH duo is considered the most established growth-stimulation protocol in the research literature. Tesamorelin is a GHRH analog (growth hormone-releasing hormone): it stimulates the pituitary gland to produce growth hormone. Ipamorelin is a selective ghrelin secretagogue (GHRP): it amplifies this same signal via a different receptor pathway. The two mechanisms combine to produce more pronounced GH peaks than each compound taken separately, which explains the popularity of this pairing in body composition research.

Level of evidence The GHRP + GHRH principle is the best-characterized growth-stimulation protocol in the literature — each class has decades of research behind it, both separately and in combination.

GHRP + GHRH combined

Ipamorelin (ghrelin receptor) and Tesamorelin (GHRH receptor) — two pathways toward the same hormone.

Rhythm preserved

Mechanism studied to preserve the natural pulsatility of GH secretion.

Reconstitution

Each vial is reconstituted separately with the bacteriostatic water provided in the kit. Disinfect the septum with an alcohol swab, inject the water slowly along the wall of the vial, without shaking — gently swirl between your hands to dissolve.

Use the dosage calculator to determine the exact volume to draw for each peptide. Store reconstituted solutions in the refrigerator (2-8°C).

Frequently asked questions

Are both peptides reconstituted together?

No, each vial is reconstituted separately with its own bacteriostatic water.

Is the reconstitution kit enough for the whole pack?

Yes, the kit provided (water + syringes + swabs) covers the preparation of both products in the pack.

Can I buy the peptides separately?

Yes, each one is also available individually in the catalog, but the pack works out 15% cheaper than buying separately.
