Dermorphin in brief
Dermorphin comes in 4 strengths from 2mg to 20mg per vial, each a sealed box of ten, from $25.40 to $133.06 a box. Per mg the spread is wide: DR20 (20mg x 10 vials) works out at $0.665 per mg against $1.270 per mg for DR2 (2mg x 10 vials), 48 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
Nothing is held on the shelf: every strength is special order, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What Dermorphin is
Dermorphin is a heptapeptide amide first isolated from the skin of a South American frog: Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2, average mass 802.9. It was the first peptide from an animal found to contain a D-amino acid, the D-alanine at position 2, which is what the label’s bracketed note refers to.
Two tyrosines and a phenylalanine give it strong UV absorbance and moderate hydrophobicity. There is no methionine, tryptophan, cysteine, asparagine or glutamine, so neither oxidised forms nor side-chain deamidation are the impurities to expect; its related substances are synthesis by-products, among them the L-alanine diastereomer, which has the same formula and mass; the desk answers for it on a particular batch.
Dermorphin beside Selank and SS-31
Dermorphin works out at $0.665 per mg at 20mg (DR20, in 50-box lots), its lowest. Its neighbours: Selank at $0.740 per mg at 10mg (SK10), 751.9 g/mol; SS-31 at $0.771 per mg at 50mg (2S50), 639.8 g/mol, another short amide with a D residue in it, D-arginine at its N-terminus, beside the non-coded 2,6-dimethyltyrosine.
Reading a Dermorphin certificate of analysis (COA)
Identity by mass. Average mass 802.9 (C40H50N8O10). In electrospray the protonated ions come near m/z 803.9 (singly charged), m/z 402.5 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: no methionine, tryptophan or cysteine in the chain, so oxidised forms are not the impurity to expect.
- Deamidation: no asparagine or glutamine, but the C-terminal amide can hydrolyse to the free acid, 0.984 heavier, inside the tolerance of the average-mass line; telling the acid from the amide takes a high-resolution mass, which the certificate does not carry.
- Charge: near neutral pH about +1, basic.
- The L-alanine diastereomer has the same formula and mass as dermorphin; telling the two apart takes HPLC run beside a reference of the other, which the certificate does not carry.
Worked out from what the sheet holds for this line; the batch certificate is the record. How to read one, and verify a batch number.

Questions about Dermorphin
Which lines sit closest to Dermorphin by mass?
Two, both within twenty units and both in the COA guide’s look-alikes table: Semax, which weighs 813.9, eleven units heavier, and GHRP-2, at 818.0, heavier by 15.1. The chains share little else: Semax carries a methionine, GHRP-2 a tryptophan and a naphthylalanine, and dermorphin neither: its aromatic residues are two tyrosines and a phenylalanine, with the D-alanine at 2 between the first tyrosine and the phenylalanine.
How much does Dermorphin cost?
It is sold only by special order, 50 boxes per strength, from $25.40 a sealed box of 10 vials, up to $133.06 for the largest strength, which works out at $0.665 per mg at its best-priced size. The smallest order is 50 boxes of DR2, $1,270.00 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.
Which Dermorphin size is cheapest per mg?
DR20, 20mg x 10 vials, at $0.665 per mg, which is 48 percent less per mg than DR2, at $1.270 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.
Can I buy a single vial of Dermorphin?
No, and not a single box either. Dermorphin is a special-order line, brought in on a 50-box minimum rather than held in stock, so the smallest order is 50 sealed boxes of one strength: for DR2, 2mg x 10 vials, that is 50 boxes at $25.40, $1,270.00 of goods. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which Dermorphin strengths are in stock today?
None today. DR2, DR5, DR10 and DR20 are special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is Dermorphin stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of Dermorphin?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. Dermorphin is supplied as a powder in a sealed glass vial and in no other presentation. Its specification sheet carries the catalogue name, Dermorphin(dp). Boxes are not split.
Is a certificate of analysis (COA) provided for Dermorphin?
Yes. For Dermorphin the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
