Gonadorelin vs HCG
The two are priced in different units, per mg and per IU, so there is no per-unit verdict here; per vial, Gonadorelin is $4.47 (GND5, special order, 50-box minimum) and HCG $7.79 (G5K, special order, 50-box minimum). Gonadorelin is offered in 3 strengths (2mg to 10mg), HCG in 2 (5000IU to 10000IU). Neither is on the shelf today.

What differs between Gonadorelin and HCG
A ten-residue synthetic peptide against a two-chain glycoprotein, sold by the milligram and by the international unit. Gonadorelin is the native GnRH decapeptide, pyroglutamate at the N-terminus and an amide at the C-terminus, mass 1,182.3, made by solid-phase synthesis and released on HPLC purity like any other peptide here. HCG is a heterodimer of a 92-residue alpha subunit and a 145-residue beta subunit, heavily glycosylated, so it has no single mass and is labelled and priced in international units rather than milligrams. Its certificate reports purity by size exclusion and SDS-PAGE rather than an RP-HPLC area percentage, identity against the reference standard by the method it names, endotoxin and net content.

Questions
What is the difference between Gonadorelin and HCG?
A ten-residue synthetic peptide against a two-chain glycoprotein, sold by the milligram and by the international unit. Gonadorelin is the native GnRH decapeptide, pyroglutamate at the N-terminus and an amide at the C-terminus, mass 1,182.3, made by solid-phase synthesis and released on HPLC purity like any other peptide here.
How many residues does each one carry?
Gonadorelin ten, in one chain with neither end free: a pyroglutamate starts it and a glycinamide ends it. HCG carries 237 across two chains held together without a covalent bond, the 92-residue alpha subunit that the glycoprotein hormones share, HMG’s FSH and LH among them, and the 145-residue beta subunit that is HCG’s alone. Its sugars come on top of those residues, which leaves it without one mass, where gonadorelin has 1,182.3.
Which is cheaper, Gonadorelin or HCG?
The two are priced in different units, per mg and per IU, so there is no per-unit verdict here; per vial, Gonadorelin is $4.47 (GND5, special order, 50-box minimum) and HCG $7.79 (G5K, special order, 50-box minimum).
Which comes in more strengths, Gonadorelin or HCG?
Gonadorelin, with 3 against 2. Every strength is a separate line with its own code, price and stock state.
Are Gonadorelin and HCG made to the same specification?
No. Gonadorelin is released on an RP-HPLC purity of at least 98.0 percent and identified by mass against its calculated 1,182.3. HCG, a glycoprotein with no single mass, is released on size exclusion and SDS-PAGE against the limit stated on its batch certificate and identified against the reference standard by the method that certificate names. Both carry net content within 5 percent of label and a retest date on the batch record.
