SNAP-8

A cosmetic signalling peptide developed for topical formulations. Laboratory and skin-product evidence does not support systemic injection.

Evidence context, not a personal protocol

Quantities below reproduce their stated source context—label, human study, laboratory work or educational guide. They do not assess suitability, product equivalence or individual risk.

Dosage and protocol evidence

Each card states what the quantities are based on. A third-party or animal schedule is not a validated human dose.

Formulation MathTopical onlyTwice daily in testing
Topical cosmetic formulation arithmetic

Finished-formula concentrations of 0.0015%-0.005% correspond to 15-50 ppm; 10 mg supplies 200 g of a 0.005% formula

Manufacturer-oriented testing used topical application twice daily for 28 days. The calculation does not validate injection or establish independent clinical efficacy.

Evidence summary

A cosmetic signalling peptide developed for topical formulations. Laboratory and skin-product evidence does not support systemic injection.

Protocol basis

The evidence is formulation-specific to topical cosmetic use. No injectable protocol is presented because none is supported by matched human evidence.

What remains uncertain

Systemic pharmacokinetics, injection safety, target engagement and clinical outcomes are unknown.

Warnings and contraindications

Topical cosmetic ingredients are not validated for injection.
No controlled human systemic administration protocol was identified.
Excipient safety and skin penetration data do not establish injectable sterility or exposure.
