Rigin 200mg (Palmitoyl Tetrapeptide-7) Topical Overview
Rigin 200mg (Palmitoyl Tetrapeptide-7) Topical from Peptide Science is the synthetic palmitoylated tetrapeptide with the sequence Pal-Gly-Gln-Pro-Arg, supplied as a topical research formulation for in-vitro dermal-cell and cytokine-pathway research. The compound is studied alongside Matrixyl and Syn-Coll in the multi-peptide signal-peptide subset of cosmetic-research material.
Compound Class and Mechanism
Rigin is the palmitoylated tetrapeptide derived from a tuftsin-related sequence, characterised in preclinical research for cytokine-modulation effects in cultured fibroblasts and keratinocytes. The compound has been documented for reduction of interleukin-6 and other inflammatory cytokine markers in cell-culture models. The palmitoyl conjugation provides lipophilic skin-cell penetration for topical-formulation research.

Handling and Reconstitution
The topical research formulation is supplied for in-vitro cell-culture and animal-model dermatology work, not as a finished cosmetic product. The working concentration used in any given research protocol is set by the principal investigator. Aliquoting reconstituted stock for single-use storage is the standard handling practice for short signal peptides where repeated freeze-thaw cycles can affect activity.
Quality and Shipping
Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation. A Certificate of Analysis accompanies every order. Material is prepared in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in insulated, light-protected packaging via overnight or two-day courier.
