Ipamorelin vs GHRP-6
Strength for strength, Ipamorelin costs less per mg at the two strengths both are offered in: at 5mg $0.623 per mg against $0.852 (IP5, G65 in 50-box lots), at 10mg $0.509 per mg against $0.727 (IP10, G610 in 50-box lots). By the single box, Ipamorelin is the only option, from $0.509 per mg at 10mg (IP10); every GHRP-6 line is special order. Ipamorelin is offered in 3 strengths (2mg to 10mg), GHRP-6 in 2 (5mg to 10mg); Ipamorelin has 2 on the shelf today, GHRP-6 none (special order, 50-box minimum). The least either takes: one box of IP5 at $31.16, four for a first order’s $100 minimum, against 50 boxes of G65, $2,129.50 of goods.

What differs between Ipamorelin and GHRP-6
Ipamorelin is a five-residue chain with no tryptophan, Aib-His-D-2-Nal-D-Phe-Lys-NH2, and GHRP-6 a six-residue chain with two, His-D-Trp-Ala-Trp-D-Phe-Lys-NH2; they share the histidine and the closing D-Phe-Lys-NH2. GHRP-6 has its tryptophans at position 2 (D) and position 4 (L), so GHRP-6 can form tryptophan oxidation products, and the two indole rings give the chain strong absorbance at 280 nm; ipamorelin’s related substances come from synthesis, such as the tetrapeptide missing its Aib. GHRP-6 is the heavier on the mass line, 873.0 to ipamorelin’s 711.9. FDA’s substance register lists GHRP-6 under a second name, Hexapeptide-2.

Questions
What is the difference between Ipamorelin and GHRP-6?
Ipamorelin is a five-residue chain with no tryptophan, Aib-His-D-2-Nal-D-Phe-Lys-NH2, and GHRP-6 a six-residue chain with two, His-D-Trp-Ala-Trp-D-Phe-Lys-NH2; they share the histidine and the closing D-Phe-Lys-NH2.
Where are ipamorelin’s and GHRP-6’s ions at high resolution?
Singly protonated, ipamorelin gives m/z 712.393 and GHRP-6 873.452, from monoisotopic masses of 711.386 and 872.445; doubly protonated, 356.700 against 437.230. Those are the high-resolution figures; on an average-mass reading the same ions come near 712.9 and 874.0; N-acetyl ipamorelin, a different substance with its own record, weighs 753.9, 42.0 more than ipamorelin.
Read back from the lysine amide, at which residue do ipamorelin and GHRP-6 part?
At the third from the end. The last two match, D-phenylalanine then lysine amide; next comes ipamorelin’s D-2-naphthylalanine where GHRP-6 has its L-tryptophan, a naphthyl side chain against an indole, and the D form against the L. Fourth from the end, ipamorelin has its histidine and GHRP-6 an alanine; fifth, Aib against D-tryptophan. GHRP-6 then runs one residue further, to the histidine that opens it, so the histidine both carry stands first in GHRP-6 and second in ipamorelin.
Which is cheaper per mg, Ipamorelin or GHRP-6?
Strength for strength, Ipamorelin costs less per mg at the two strengths both are offered in: at 5mg $0.623 per mg against $0.852 (IP5, G65 in 50-box lots), at 10mg $0.509 per mg against $0.727 (IP10, G610 in 50-box lots).
What are the molecular weights of Ipamorelin and GHRP-6?
Ipamorelin’s calculated average mass is 711.9 g/mol and GHRP-6’s 873.0 g/mol, 161.1 apart; in electrospray the ions come at m/z 712.9 (1+) for Ipamorelin against 874.0 and 437.5 (1+ and 2+) for GHRP-6. On each certificate the measured mass is matched to the line’s calculated average mass, within about one unit, as how to read a peptide COA sets out.
Are Ipamorelin and GHRP-6 made to the same specification?
Yes: both are supplied to purity not less than 98.0 percent by RP-HPLC and net content within 5 percent of label, and each certificate reports those with a measured mass, matched to the calculated figure on each sheet. The retest date is on the batch record. What differs is each molecule’s own chemistry, described on its compound page.
