GHRP-2 in brief
GHRP-2 comes in 2 strengths from 5mg to 10mg per vial, each a sealed box of ten, from $42.59 to $72.72 a box. Per mg the spread is narrow: G210 (10mg x 10 vials) works out at $0.727 per mg against $0.852 per mg for G25 (5mg x 10 vials), 15 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 GHRP-2 is
GHRP-2, also called pralmorelin, is a synthetic hexapeptide amide: D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, average mass 818.0, supplied as the acetate. Three of its six residues are D-amino acids and one is the non-coded 2-naphthylalanine. Its last two, D-phenylalanine and lysine amide, are the same in ipamorelin, GHRP-6 and hexarelin. Its formula is C45H55N9O6.
The single tryptophan is the residue that ages: under light it gives kynurenine and hydroxytryptophan products. The naphthyl and tryptophan side chains make it hydrophobic for its size. Store dark.
Registry and identity
- Pralmorelin is the INN given to GHRP-2 in WHO Proposed INN List 77, with KP-102 as its research code, and FDA's GSRS files it as UNII E6S6E1F19M under CAS 158861-67-7, with ChEMBL CHEMBL106593 and PubChem CID 6918245. FDA GSRS
- The salt that holds a USAN and a JAN is the dihydrochloride, pralmorelin dihydrochloride (code WAY-GPA-748, UNII R4AVR27MM8, CAS 158827-34-0), C45H55N9O6 with two HCl, 890.9, of which hydrogen chloride is 8.2 percent (worked from that formula). FDA GSRS
- GSRS defines all six stereocentres, D at alanine 1, at the 3-(2-naphthyl)alanine of position 2 and at phenylalanine 5, and an epimer at any of them leaves C45H55N9O6 and the mass unchanged; telling them apart takes HPLC run beside a reference of the epimer, which the certificate does not carry. FDA GSRS
- At high resolution the singly protonated monoisotopic ion is at m/z 818.435 (doubly protonated 409.721), about 0.56 below the 819.0 that the average mass gives, worked from C45H55N9O6 with NIST isotope masses. PubChem, NIST

GHRP-2 beside CJC-1295 no DAC, Ipamorelin and Hexarelin
GHRP-2 works out at $0.727 per mg at 10mg (G210, in 50-box lots), its lowest. Its neighbours: CJC-1295 no DAC at $1.747 per mg at 10mg (CND10), 3,368.0 g/mol, set side by side in CJC-1295 no DAC vs GHRP-2, a 29-residue amide whose only D-residue is a D-alanine, at 2 where GHRP-2 has its own at 1, and which has no tryptophan; Ipamorelin at $0.553 per mg at 10mg (IP10), 711.9 g/mol, set side by side in Ipamorelin vs GHRP-2, one residue shorter and without a tryptophan, yet carrying the same D-2-naphthylalanine; Hexarelin at $1.454 per mg at 5mg (HX5, in 50-box lots), 887.1 g/mol, set side by side in GHRP-2 vs Hexarelin, His-D-2-MeTrp in front where GHRP-2 has D-Ala-D-2-Nal, and 69.1 heavier.
Also set side by side: GHRP-2 vs GHRP-6.
Reading a GHRP-2 certificate of analysis (COA)
Identity by mass. Average mass 818.0 (C45H55N9O6). In electrospray the protonated ions come near m/z 819.0 (singly charged), m/z 410.0 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: 1 tryptophan, which oxidises to kynurenine and hydroxy forms under light. Kynurenine makes the chain 4 heavier and a hydroxy tryptophan 16.
- 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 +2, basic.

Questions about GHRP-2
Is pralmorelin the same as GHRP-2?
Yes. Pralmorelin and GHRP-2 are names for the same thing. Pralmorelin is another name for the GHRP-2 peptide; this line is its acetate salt, and its sheet gives the peptide itself, C45H55N9O6 at 818.0. The certificate and the vial label carry GHRP-2 Acetate, which is the name the batch is released under.
What are GHRP-2’s sequence, formula, molecular weight and CAS number?
D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2: C45H55N9O6, molecular weight (average mass) 818.0, CAS 158861-67-7 (FDA GSRS UNII E6S6E1F19M), the number for the peptide itself. Pralmorelin dihydrochloride, a different salt, is filed apart under CAS 158827-34-0.
What does the 55.0 between GHRP-2 and GHRP-6 consist of?
One carbon, one hydrogen and three nitrogens: C46H56N12O6 less C45H55N9O6 leaves CHN3, about 55.0. All of it lies in the first two residues, the only ones that differ. GHRP-6 starts His-D-Trp, and the histidine ring holds two nitrogens and the D-tryptophan indole one more; GHRP-2 starts D-Ala-D-2-Nal, whose side chains hold none. Both formulas keep six oxygens, one carbonyl for each residue, the last of them in the C-terminal amide.
How much does GHRP-2 cost?
It is sold only by special order, 50 boxes per strength, from $42.59 a sealed box of 10 vials, up to $72.72 for the largest strength, which works out at $0.727 per mg at its best-priced size. The smallest order is 50 boxes of G25, $2,129.50 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.
Which GHRP-2 size is cheapest per mg?
G210, 10mg x 10 vials, at $0.727 per mg, which is 15 percent less per mg than G25, at $0.852 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 GHRP-2?
No, and not a single box either. GHRP-2 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 G25, 5mg x 10 vials, that is 50 boxes at $42.59, $2,129.50 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 GHRP-2 strengths are in stock today?
None today. G25 and G210 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 GHRP-2 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 GHRP-2?
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. GHRP-2 is supplied as a powder in a sealed glass vial and in no other presentation. Its specification sheet carries the catalogue name, GHRP-2 Acetate. Boxes are not split.
Is a certificate of analysis (COA) provided for GHRP-2?
Yes. For GHRP-2 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.
