Gonadorelin in brief
Gonadorelin comes in 3 strengths from 2mg to 10mg per vial, each a sealed box of ten, from $26.20 to $89.34 a box. Per mg the spread is wide: GND5 (5mg x 10 vials) works out at $0.893 per mg against $1.310 per mg for GND2 (2mg x 10 vials), 32 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 Gonadorelin is
Gonadorelin is the native gonadotropin-releasing hormone decapeptide, pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2, average mass 1182.3, supplied as the acetate. It begins with a pyroglutamate and ends with a glycinamide, so neither terminus is free; the residue at position 6 is glycine, which is the position the analogues change.
The single tryptophan is the residue that ages under light. There is no methionine, and no asparagine or glutamine to deamidate; only the C-terminal glycinamide can hydrolyse to the free acid. It is moderately hydrophilic. Compare with triptorelin, which replaces the glycine at 6 with D-tryptophan and is 129 mass units heavier.
Gonadorelin beside Kisspeptin-10, Triptorelin and HCG
Gonadorelin works out at $0.893 per mg at 5mg (GND5, in 50-box lots), its lowest. Its neighbours, on price alone: Kisspeptin-10 at $0.907 per mg at 10mg (KS10), 1,302.5 g/mol; Triptorelin at $1.403 per mg at 2mg (TA/G2, in 50-box lots), 1,311.5 g/mol; HCG, priced per IU, set side by side in Gonadorelin vs HCG.
Reading a Gonadorelin certificate of analysis (COA)
Identity by mass. Average mass 1182.3 (C55H75N17O13). In electrospray the protonated ions come near m/z 1183.3 (singly charged), m/z 592.2 (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.
- N-terminus: pyroglutamate, so there is no free amine at the start of the chain and no N-terminal degradation of the usual kind.
- Charge: near neutral pH about +1, basic.

Questions about Gonadorelin
How close is Gonadorelin to Kisspeptin-10?
Not close in sequence. Both are ten-residue amides and both carry tryptophan third in the chain, but the one run they share is Gly-Leu-Arg, which gonadorelin carries as its sixth to eighth residues and kisspeptin-10, YNWNSFGLRF-NH2, as its seventh to ninth. Gonadorelin starts from a pyroglutamate and finishes on glycinamide, kisspeptin-10 starts from tyrosine and finishes on the RF-amide that defines its family, and only kisspeptin-10 has asparagines to deamidate, two of them. By mass they are 120.2 apart, 1,302.5 against 1,182.3.
Which other sequences on this list begin with a pyroglutamate?
Two. Triptorelin begins the same way and follows gonadorelin residue for residue except at 6, where a D-tryptophan replaces the glycine; that makes it 129.2 heavier, 1,311.5 against 1,182.3, and both carry a net charge near +1. Ara-290 shares only that first residue; its eleven residues come from erythropoietin’s helix B, pGlu-EQLERALNSS, 1,257.3. It ends on a free acid, while the other two end on glycinamide, and its net charge is near -2.
How much does Gonadorelin cost?
It is sold only by special order, 50 boxes per strength, from $26.20 a sealed box of 10 vials, up to $89.34 for the largest strength, which works out at $0.893 per mg at its best-priced size. The smallest order is 50 boxes of GND2, $1,310.00 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.
Which Gonadorelin size is cheapest per mg?
GND5, 5mg x 10 vials, at $0.893 per mg, which is 32 percent less per mg than GND2, at $1.310 per mg. Larger vials never cost more per mg here, and two sizes cost the same, so match the vial to the size of the work first.
Can I buy a single vial of Gonadorelin?
No, and not a single box either. Gonadorelin 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 GND2, 2mg x 10 vials, that is 50 boxes at $26.20, $1,310.00 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 Gonadorelin strengths are in stock today?
None today. GND2, GND5 and GND10 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 Gonadorelin 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 Gonadorelin?
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. Gonadorelin is supplied as a powder in a sealed glass vial and in no other presentation. Its specification sheet carries the catalogue name, Gonadorelin Acetate. Boxes are not split.
Is a certificate of analysis (COA) provided for Gonadorelin?
Yes. For Gonadorelin 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.
