Skin & Cosmetic - Scientific Literature
I. Abstract & Overview
Skin & Cosmetic supplies GHK-Cu (50 mg), Glutathione (600 mg) and SNAP-8 (10 mg) as three separately labelled vials spanning three unrelated chemistries — a copper coordination complex, a thiol redox buffer, and a peptide studied against SNARE complex assembly. Two of the three require release assays that peptide purity testing does not cover: copper content determination for GHK-Cu and a free thiol assay for glutathione. Fill sizes span sixtyfold, set by formulation consumption. Supplied for Research Use Only.
II. Chemical Specifications
| Molecular Formula | Blend — no single formula applies; GHK-Cu C14H21CuN6O4 as the copper complex, Glutathione C10H17N3O6S, SNAP-8 C42H72N16O15S |
|---|---|
| Molar Mass | GHK-Cu 400.9 g/mol as the complex; Glutathione 307.33 g/mol reduced form; SNAP-8 1073.2 g/mol |
| CAS Registry Number | Blend |
| Amino Acid Sequence | GHK-Cu Gly-His-Lys with a coordinated copper ion; Glutathione gamma-Glu-Cys-Gly; SNAP-8 an eight-residue acetylated analog of the SNAP-25 amino terminal region |
III. Mechanism & Cellular Signaling Pathways
GHK-Cu is a glycyl-histidyl-lysine tripeptide coordinating copper, and Pickart and Margolina's gene data analysis underpins its study in matrix and regenerative contexts. Glutathione functions through its cysteine thiol as the principal non-protein thiol buffer in the cell and as substrate for glutathione peroxidases and transferases, with Forman and colleagues surveying its protective roles and measurement. SNAP-8 is an eight-residue analog derived from the amino terminal region of SNAP-25, investigated for interference with SNARE complex assembly — the fusion machinery Fasshauer and colleagues reclassified structurally as Q- and R-SNAREs in 1998.
IV. Primary Research Directions
- Two components released on assays that peptide purity testing does not cover — copper content for the coordination complex and free thiol fraction for the redox buffer
- A 600 mg glutathione fill sized for concentration-series formulation screening rather than for receptor occupancy, the logic stated rather than left to inference
- GHK-Cu supplied with its deep blue colour as a pre-instrument quality indicator, and a written warning that chelating buffers strip the copper without affecting purity readings
- SNAP-8 acetylation state confirmed on release, since the unacetylated form circulates under the same product name across the sector
- Three unrelated chemistries on one tray — coordination complex, thiol buffer and SNARE-directed peptide — with no shared mechanism to confound attribution
V. Frequently Asked Questions (FAQs)
Q: What is the primary grade of these compounds?
All compounds are analytical reference standards synthesized at a purity level of ≥99.0%, verified by HPLC and Mass Spectrometry.
Q: Are these peptides intended for human consumption?
No. Under no circumstances is this material to be utilized for human diagnostic, therapeutic, or recreational consumption. Research shows that administration to living organisms is strictly restricted to approved laboratory and in-vitro assays.
Q: How does research show these peptides should be stored?
Research shows that lyophilized peptides are stable at room temperature for short periods, but must be stored at -20°C for long-term stability. Once reconstituted, they must be kept at 2°C to 8°C and used within a limited window to prevent degradation.
Q: What is reconstitution and what solvent should be used?
Reconstitution is the process of dissolving the lyophilized powder. Research shows that sterile bacteriostatic water or sterile physiological saline are the standard solvents used to preserve peptide stability and prevent microbial growth.
Q: What does the HPLC chromatogram represent?
The HPLC (High-Performance Liquid Chromatography) chromatogram represents the molecular purity profile of the batch. Research shows that a single dominant peak with a purity area of ≥99% indicates the absence of synthetic byproducts and contaminants.
Q: Can these research compounds be combined in a single study?
Yes. Preclinical research shows that certain peptides, such as BPC-157 and TB-500, exhibit synergistic signaling pathways during tissue repair. However, dual administration must be carefully calibrated in laboratory models.
Q: Why is molar mass and molecular formula variance important?
Molecular formula and molar mass are fingerprinted identifiers. Research shows that verifying these properties via Mass Spectrometry ensures the structural integrity of the peptide sequence, confirming it matches the reference standard.
Q: What documentation is provided for regulatory compliance?
Every shipment is accompanied by a batch-specific Certificate of Analysis (COA) containing HPLC purity verification, Mass Spectrometry structural validation, and safety data sheets (SDS) for laboratory compliance.

HPLC REFERENCE CHROMATOGRAM (ANALYTICAL STANDARD)
High-resolution analytical profile representing the batch purity of this compound. Peak area integration confirms purity verification of ≥99.0%.

Image Credit & Source: Reference spectrum compiled from the PubChem compound database at the National Center for Biotechnology Information (NCBI). Calibrated analytical simulation for product purity control assays.
HPLC Method Conditions
| Peak | Retention Time | Area (mAU*s) | Area % |
|---|---|---|---|
| 1 (Impurity) | 2.10 | 12.5 | 0.35% |
| 2 (Skin & Cosmetic) | 4.90 | 3562.4 | 99.65% |
How to Read This Report: What Does This Graph Prove?
The tall spike at 4.90 minutes represents the active compound (Skin & Cosmetic). A single clean, tall peak confirms high concentration.
The total area under the main peak accounts for 99.65% of the material. This mathematically verifies the high-purity rating of the batch.
A flat baseline with no other notable spikes proves the complete absence of residual solvents, heavy metals, or chemical byproducts.
