Quick answer: Greyverse is not a synonym you can paste onto every Palmitoyl Tetrapeptide-20 drum. As published by Clariant, Greyverse is Glycerin (and) Water (and) Palmitoyl Tetrapeptide-20 Amide. Palmitoyl Tetrapeptide-20 on this site is sold as a neat powder under the non-amide INCI string—treat it as a Greyverse-oriented alternative only when sequence and form match what the brief requires.
Scalp placement and powder dosing are in Palmitoyl Tetrapeptide-20 on the Scalp: Sequence and Powder Dose.
The sequence that belongs to the trade name
Industry listings of Palmitoyl Tetrapeptide-20 Amide give the sequence Pal-His-Phe-Arg-Trp-NH2—a palmitoylated copy of the His-Phe-Arg-Trp motif in alpha-melanocyte-stimulating hormone. Clariant’s public Greyverse page states the amide INCI and an alpha-MSH origin. It does not replace the sequence line on your COA. Require the sequence in writing before you treat a powder as that grade.
There is no product page here for Palmitoyl Tetrapeptide-20 Amide as a separate SKU. If the brief names the amide, do not silently switch the INCI to the acid form without supplier confirmation.
A PubChem record that is a different peptide
PubChem’s compound titled Palmitoyl tetrapeptide-20 is palmitoyl-Pro-Glu-Lys-Lys (PEKK). That is not His-Phe-Arg-Trp. Do not pull a CAS, molecular weight, or structure from that record onto a Greyverse specification. Match the lot to the amide sequence, not to a similar title.
Solution percent and powder percent
Greyverse is sold as a glycerin-and-water solution of the peptide. A neat ≥98% powder is a different commercial form. A use level quoted for the solution is the solution, not the peptide, unless the TDS says otherwise. Copying that numeral onto a high-assay powder overstates the dose. This site’s powder page suggests about 0.005–0.05% for the neat peptide—set the pilot from the COA you buy.
A peptide buyers place next to it
Melitane GL, as published by its supplier, is Glycerin (and) Water (and) Dextran (and) Acetyl Hexapeptide-1. That is a separate material for skin color pathways, not a substitute on a purchase order for Palmitoyl Tetrapeptide-20 or for the Greyverse amide.
What changes on the purchase order
| Field | Greyverse (public sheet) | This site powder |
|---|---|---|
| Peptide INCI | Palmitoyl Tetrapeptide-20 Amide | Palmitoyl Tetrapeptide-20 |
| Carrier | Glycerin + water solution | Neat lyophilized powder |
| Sequence to require | Pal-His-Phe-Arg-Trp-NH2 (confirm on COA) | Same HFRW motif if claiming equivalence—confirm in writing |
| Dose math | Solution % ≠ neat peptide % | Follow powder TDS / COA |
What to put in the quote or sample email
- Trade name Greyverse only as a reference, never instead of the INCI
- Exact INCI (amide vs non-amide) and written sequence
- Form: solution vs neat powder, and peptide assay
- Cool-down / pH needs
- Sample pack size, plus COA, SDS, and TDS
Documents and samples for the powder are on the Palmitoyl Tetrapeptide-20 page. Send the inquiry there once sequence and form are locked.
