HGH Fragment 176-191 in brief
HGH Fragment 176-191 comes in one strength, 5mg x 10 vials, at $56.10 for the box of ten ($5.61 a vial, $1.122 per mg).
Nothing is held on the shelf: this is a special-order line, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What HGH Fragment 176-191 is
HGH Fragment 176-191 is the 16-residue C-terminal segment of human growth hormone, LRIVQCRSVEGSCGF preceded by residue 176, with one disulfide bridge between its two cysteines. The first residue is either the native phenylalanine, 1,799.1 in all, or the tyrosine of AOD9604, 1,815.1, 16.0 heavier; the desk answers which for a given batch, and the two lines are separate batches under separate names.
One glutamine and no methionine or tryptophan, so its related substances of note are the reduced or dimerised chain rather than an oxidised one. The disulfide makes the chain two units lighter than the reduced form. It dissolves readily.
Registry and identity
- PubChem's compound titled HGH Fragment 176-191 (CID 172966176, also listed as GLXC-21568) is the native sequence, Phe-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe with its two cysteines bridged, recorded as a 1:1 acetate, C80H127N23O24S2, average mass 1859.1. PubChem
- UniProt's entry for human growth hormone, P01241, ends with exactly these 16 residues: they are 202 to 217 of the 217-residue precursor, 176 to 191 of the 191-residue hormone once the 26-residue signal peptide is removed, with cysteines 208 and 215 bridged. UniProt
- Put tyrosine in the first position and the chain becomes a different substance on file, LAT-8881, also coded AOD9604 (FDA UNII 7UP768IP4M, CAS 221231-10-3). FDA GSRS
- Taking the acetic acid out of PubChem's formula leaves the peptide at C78H123N23O22S2, average mass 1799.1 and monoisotopic 1797.865 (worked from that formula with NIST isotope masses), 16.0 below AOD9604's 1815.1: the one oxygen a tyrosine carries beyond a phenylalanine. PubChem 172966176, PubChem 71300630, NIST
- FLRIVQCRSVEGSCGF contains no tyrosine or tryptophan, so the native chain is nearly transparent at 280 nm and is assayed at peptide-bond wavelengths, 210 to 220 nm, whereas the tyrosine of the AOD9604 form adds absorbance near 275 nm. UniProt, FDA GSRS
A listing in these registers identifies a substance; it is not an approval of this line.
HGH Fragment 176-191 beside AOD9604
Its neighbour, on price alone: AOD9604 at $2.036 per mg at 5mg (AD5), set side by side in AOD9604 vs HGH Fragment 176-191.
Reading an HGH Fragment 176-191 certificate of analysis (COA)
- Oxidation: 2 cysteines held in a disulfide bridge, and the reduced form, with the bridge opened, is 2 heavier. Store in the dark and keep the vial sealed.
- Deamidation: 1 glutamine. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
- Charge: near neutral pH about +1, basic.

Questions about HGH Fragment 176-191
Which groups in HGH Fragment 176-191 carry a charge near neutral pH?
Five groups. Arginine 3, arginine 8 and the free amine at the N-terminus are positive; glutamate 11 is negative, as is the C-terminal carboxylate of phenylalanine 16. That nets about +1, the charge this page gives, and the first residue does not move it, since neither phenylalanine nor tyrosine is charged: AOD9604’s page gives +1 as well. In growth hormone’s count those arginines are 178 and 183, the glutamate 186; the two cysteines are bridged, so neither holds a free thiol.
How much does HGH Fragment 176-191 cost?
It is sold only by special order, 50 boxes per strength, at $56.10 a sealed box of 10 vials, which works out at $1.122 per mg. The smallest order is 50 boxes of FR5, $2,805.00 of goods, with freight included to a US address. The price per vial is in this page’s price table.
What does HGH Fragment 176-191 cost per mg?
It is offered in one size, FR5 at 5mg x 10 vials, which works out at $1.122 per mg at $56.10 a sealed box of 10 vials, sold by special order with a 50-box minimum. Freight included to US addresses from $1,000 of goods.
Can I buy a single vial of HGH Fragment 176-191?
No, and not a single box either. HGH Fragment 176-191 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 FR5, 5mg x 10 vials, that is 50 boxes at $56.10, $2,805.00 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.
Is HGH Fragment 176-191 in stock today?
No. FR5 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is HGH Fragment 176-191 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 HGH Fragment 176-191?
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. HGH Fragment 176-191 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 HGH Fragment 176-191?
Yes. For HGH Fragment 176-191 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.
