Dihexa in brief
Dihexa comes in 2 strengths from 5mg to 10mg per vial, each a sealed box of ten, from $28.60 to $42.59 a box. Per mg the spread is wide: DH10 (10mg x 10 vials) works out at $0.426 per mg against $0.572 per mg for DH5 (5mg x 10 vials), 26 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 Dihexa is
Dihexa is a small peptidomimetic rather than a conventional peptide: N-hexanoyl-tyrosyl-isoleucyl-(6)-aminohexanoic amide, formula C27H44N4O5, average mass 504.7. A fatty acyl cap at one end and an aminohexanoic spacer at the other flank a two-residue core, which is why it behaves more like a lipophilic small molecule than like the peptides around it.
It is poorly soluble in water. There is nothing in it to oxidise or deamidate. Identity by mass and purity by HPLC with UV detection are two of the certificate’s three results, and net content is the third.
Dihexa beside Semax and Selank
Dihexa works out at $0.426 per mg at 10mg (DH10, in 50-box lots), its lowest. Its neighbours, on price alone: Semax at $0.740 per mg at 10mg (XA10), 813.9 g/mol; Selank at $0.740 per mg at 10mg (SK10), 751.9 g/mol.
Reading a Dihexa certificate of analysis (COA)
Identity by mass. Average mass 504.7 (C27H44N4O5). In electrospray the protonated ions come near m/z 505.7 (singly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Low water solubility is the character of the molecule, not a fault.

Buy Dihexa in bulk
Dihexa is sold in bulk by the sealed box of ten vials, and every account starts at list price. Two discounts can lower it, the size of one order (from $5,000 of goods) or the account’s tier (from lifetime paid spend), and the better one applies, never both.

Questions about Dihexa
How does Dihexa differ from Semax and Selank, its neighbours?
Its peptide part is only two residues long. Dihexa is tyrosine and isoleucine between an N-hexanoyl cap and a 6-aminohexanoic amide, C27H44N4O5 at 504.7, which leaves it closer to a lipophilic small molecule and poorly soluble in water. Semax and Selank are heptapeptides of coded residues, 813.9 and 751.9; of the three, only Semax has a residue to oxidise, the methionine that opens its chain.
How do Dihexa’s four parts add up to C27H44N4O5?
Read along the chain, the hexanoyl cap is C6H11O, tyrosine C9H9NO2, isoleucine C6H11NO and the 6-aminohexanoic amide C6H13N2O, which sum to C27H44N4O5. By average mass the cap weighs about 99.2, tyrosine 163.2, isoleucine 113.2 and the amide end 129.2, so the two coded residues hold 276.3 of the 504.7, a little over half. The cap carries no nitrogen; tyrosine and isoleucine carry one each and the amide end two. Of the five oxygens, four sit in carbonyls and one in the tyrosine’s phenol.
How much does Dihexa cost?
It is sold only by special order, 50 boxes per strength, from $28.60 a sealed box of 10 vials, up to $42.59 for the largest strength, which works out at $0.426 per mg at its best-priced size. The smallest order is 50 boxes of DH5, $1,430.00 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.
Which Dihexa size is cheapest per mg?
DH10, 10mg x 10 vials, at $0.426 per mg, which is 26 percent less per mg than DH5, at $0.572 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 Dihexa?
No, and not a single box either. Dihexa 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 DH5, 5mg x 10 vials, that is 50 boxes at $28.60, $1,430.00 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 Dihexa strengths are in stock today?
None today. DH5 and DH10 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 Dihexa 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 Dihexa?
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. Dihexa is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for Dihexa?
Yes. For Dihexa 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.
