Palmitoyl Tetrapeptide-7 vs GHRP-6

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.

Side-by-Side Comparison

AspectPalmitoyl Tetrapeptide-7GHRP-6
MechanismSuppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides.Acts as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects.
Typical DosageTopical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex.Typical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects.
AdministrationTopical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin.Subcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting.
Side EffectsExcellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin.Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes.
