Topical delivery of growth hormone releasing pepti... - GHRP-6 Study

Key Findings

Non‑ionic liposomal carriers dramatically increased GHRP‑6 penetration through hairless mouse skin.

The lipid composition of the liposomes can be tuned to control how much peptide gets through.

The same liposomal system also boosted transport of other water‑soluble compounds like mannitol, suggesting a broader use for hydrophilic drugs.

Practical Outcomes

At this stage you can't just spray or rub regular GHRP‑6 on your skin and expect it to work. If you want a topical route, you would need a specially formulated liposomal cream or gel, which currently exists only in research settings. Keep an eye out for commercial products that use this technology, but for now stick to proven injection methods.

Summary

This lab study showed that putting GHRP‑6 inside tiny fat‑based bubbles (liposomes) helps the peptide move through mouse skin in a dish. The researchers think the same trick could let you apply peptide creams that actually reach deeper skin layers, but they only tested it in vitro, not on people.

Abstract

The results of this study clearly demonstrates the utility of novel non-ionic liposomal systems in facilitating transfer of GHRP-6 into and across deeper strata of skin following topical application. These findings indicate that it may be possible to deliver therapeutic doses of a wide variety of peptides to local skin tissue via topical application. The results also suggest the possibility of controlled enhancement of skin penetration or metered polypeptide deposition through appropriate choice of liposomal lipid components. The pronounced enhancement of GHRP-6 and mannitol transport from emulsions containing the nonionic lipids suggests a promising delivery system for hydrophilic drugs in general.
