Body-contour, marine and botanical peptide solutions

Acetyl Hexapeptide-38 (Adifyline) for volume-look formulas, Pepti-slim for body-contour products, caviar, marine, pea and elastin peptide solutions. Most of these trade grades have no verified sequence or CAS, so their cards say “confirm on CoA” instead of listing one.

What sizes are peptide solutions sold in?

Every peptide solution is sold in seven sizes: 0.33 oz (10 mL) sample, 1 oz (30 mL), 4 oz (118 mL), 8 oz (237 mL), 16 oz (473 mL), 32 oz (946 mL) and 1 gallon (3.78 L). The price on the grid is the 0.33 oz (10 mL) size. For more than a gallon, or for delivery outside the US, use the quote form.

Why is the CAS number "Mixture" or "N/A" on some cards?

Trade blends such as Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7, Hesperidin Methyl Chalcone + Dipeptide-2 + Palmitoyl Tetrapeptide-7 and Acetyl Tetrapeptide-3 + Red Clover Extract contain several registered substances, so the card says Mixture and lists the component CAS numbers that are published. Some sequences and trade grades have no CAS number we could verify; those cards say N/A instead of showing a number we cannot source.

Why don’t the cards give a use percentage?

Peptide content differs between grades and suppliers, so a percentage that is right for one lot can be wrong for another. Use the level on the supplier CoA or technical data sheet for the lot you receive.

Why are some peptides listed under several SKUs?

Acetyl Tetrapeptide-5, Acetyl Tetrapeptide-3 + Red Clover Extract, Copper Tripeptide-1 and Myristoyl Pentapeptide-17 each appear under three SKUs that come from different supplier source packs. The INCI is the same; the peptide content can differ, so compare the CoAs before switching SKUs in an existing formula.

Are the solutions preserved?

Some are: Acetyl Hexapeptide-8 Amplified Solution lists Sodium Benzoate, and Fensebiome, Acetyl Hexapeptide-30 Solution, Dawnergy and Argirelox list Caprylyl Glycol. Others are glycerin or butylene glycol bases. The INCI on each card shows which. Either way, preservative efficacy of the finished formula has to be tested.
