Prices are in US dollars per sealed box. Per unit is the box price over the milligrams, millilitres or units in the box.

Cosmetic & Skin runs to 4 compounds and 5 vial strengths. The cheapest box sold singly is Glutathione 1500mg x 10 vials (GTT) at $53.80, the most expensive SNAP-8 100mg x 10 vials (NP8100) at $436.00 a box in 50-box lots, and every price is per sealed box of ten; freight included to US addresses from $1,000 of goods. SNAP-8 comes in the most strengths, 2 of them. Per milligram, the best-priced line sold by the single box is GTT, Glutathione 1500mg x 10 vials, at $0.00359 per mg.

Nothing in this range is on the shelf today; 4 lines are made to order in about four weeks and 1 is special order, brought in on a 50-box minimum rather than held in stock. Each compound has one page carrying every strength, its specification and its questions, and the whole range is on the price list.

What sets the four apart chemically is where each one can oxidise. Glutathione is supplied reduced, as GSH, and its free thiol pairs into the disulfide GSSG, two molecules joined through their cysteines. MT-1 has norleucine where native alpha-MSH has its methionine, and neither melanotan keeps a methionine, so on both the single tryptophan is the residue that can oxidise: MT-1 is linear, thirteen residues at 1,646.9, and MT-2 a cyclic heptapeptide at 1,024.2 whose ring is a lactam, not a disulfide (MT-1 vs MT-2). SNAP-8, acetyl octapeptide-3, keeps one methionine and one glutamine, so it can form both a sulfoxide and a deamidated form.

Molecular weight, oxidation and deamidation by compound

Drawn from each compound’s sequence and specification sheet: its molecular weight, the residues that can oxidise (methionine, tryptophan, a free cysteine) and the residues that can deamidate (asparagine, glutamine); oxidation and deamidation are two of the commonest chemical changes in a peptide chain. Cysteines already joined in a disulfide bridge are marked bridged; opening the bridge adds 2 to the mass. Every lyophilised line is stored the same way whatever its sequence: minus 20 degrees Celsius, dark and dry.

Compound Form Molecular weight Residues Oxidises Deamidates
Glutathione Lyophilised 307.3 3 1 Cys none
MT-1 (Melanotan 1) Lyophilised 1646.9 13 (incl. non-coded) 1 Trp none
MT-2 (Melanotan 2) Lyophilised 1024.2 7 (incl. non-coded) 1 Trp none
SNAP-8 Lyophilised 1075.2 8 1 Met 1 Gln

Questions about this range

Which Cosmetic & Skin line is the best value per milligram?

Per milligram, the best-priced line sold by the single box is GTT, Glutathione 1500mg x 10 vials, at $0.00359 per mg. Across every compound in this range sold by the milligram in more than one strength, the larger vial costs less per milligram. Compare the per-unit column before the box price. How to compare strengths.

How many Cosmetic & Skin lines are on the shelf right now?

None today. 4 are made to order, which ships in about four weeks and can be ordered in any quantity. 1 is special order, brought in on a 50-box minimum rather than held in stock.

Can I mix Cosmetic & Skin lines with other ranges in one order?

Yes. The order minimum is counted across every line in the basket, whatever range it comes from: $100 on a first order, $300 on the second, $500 on the third and $1,000 from the fourth order on. Per line the least is one sealed box of ten vials, or 50 boxes of a line marked special order.

What comes with a Cosmetic & Skin order?

A packing list with the batch number against every line. Every batch has a certificate of analysis, sent with the shipment, and again on request; each batch is released against the specification printed on its compound page. Tracked; to a US address, freight is included from $1,000 of goods and quoted at checkout below that, and to Canada and other countries the desk quotes it.
