Best Place to Buy Kisspeptin in 2026

Short answer: Amino Club (Bureau Score 4.8), the Bureau's first choice for Kisspeptin. Below is why, the three alternatives worth knowing, and what to check before any order. Kisspeptin is sold by these stores for laboratory research use only, not for human use. It is also known as kisspeptin-10.

What to know before buying Kisspeptin

What research stores sell as kisspeptin is kisspeptin-10, the last 10 residues (YNWNSFGLRF-NH2, C-terminal amide) of kisspeptin-54, a peptide cut from the KISS1 gene product that acts on the GPR54 (KISS1R) receptor upstream of GnRH. In a 2011 study in healthy men, intravenous kisspeptin-10 raised LH in a dose-dependent way and a continuous infusion raised LH pulse frequency and testosterone.

No kisspeptin product is FDA approved (no product in Drugs@FDA, checked 1 Nov 2026), and FDA's compounding safety page (current as of 22 April 2026) lists kisspeptin-10 in category 2 for 503A compounding since 29 September 2023, citing possible immunogenicity and little or no safety information. It is not one of the six peptides in HHS's 30 October 2026 enforcement discretion policy, and WADA's 2026 list bans kisspeptin and its agonist analogues in males at all times (S2.2.1).

• What to match on the certificate: Match the identity line to C63H83N17O14, average molecular weight 1302.4 (monoisotopic 1301.63), sequence Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2 with the C-terminal amide, since a free acid version weighs about 1 more. Look for HPLC purity and a mass spec identity result on the same lot number as the vial.
• Vial sizes: Research stores sell it as 5 mg and 10 mg vials; check the label and COA say kisspeptin-10, because kisspeptin-54 is a 54-residue peptide with a far higher mass and a vial labeled only kisspeptin does not tell you which one you have.
• What it costs: 8 stores the Bureau reviews list Kisspeptin; on 1 November 2026 the in-stock list prices ran from $5.00 per mg (Amino Club, 10 mg vial) to $10.00 per mg (Amino USA, 10 mg vial), before any code.
• Storage: Suppliers generally state that a lyophilized peptide keeps best sealed and frozen (around -20 C), and that once reconstituted it should be refrigerated and used within a short window or split into aliquots and frozen, avoiding repeated freeze and thaw.

The alternatives

Each one stocks Kisspeptin and has been through the Bureau's vendor review. Listed in the Bureau's own vendor order, not by price.

Prices are list prices for single vials, read from each store by the Bureau's Vendor Watch on 1 November 2026, before any code. Prices change daily.

How the Bureau picks

The pick is the vendor at the top of the Bureau's vendor list that stocks Kisspeptin. Scores come from the scorecard, which weighs lab documentation, consistency, shipping and price, and a vendor cannot buy a score. Before any order, match the lot number on the vial to a certificate from a named third-party lab. More in the vendor scorecard and the Kisspeptin guide.

Frequently asked questions

Where is the best place to buy Kisspeptin?

The Bureau pick is Amino Club (Bureau Score 4.8). Batch COA on every product page from an 8-assay panel at an ISO 17025 lab. Alternatives that stock it: Ascension Peptides, NextgenPeps, Limitless Biotech.

Is there a discount code for Kisspeptin?

Reader deals checked by the Bureau: Amino Club, Code 100: 20% off; Ascension Peptides, Our link: 50% off every order; NextgenPeps, Code PEPTIDEBUREAU: 10% off.

How do I check a Kisspeptin vendor before ordering?

Match the batch or lot number on the vial to a certificate from a named third-party lab, check the test date, and look for identity (mass spec) as well as purity (HPLC). The Bureau's scorecard records which vendors do this.

What is the difference between kisspeptin-10 and kisspeptin-54?

Both are cut from the same KISS1 gene product. Kisspeptin-54 is the full 54-residue peptide and kisspeptin-10 is its last 10 residues, the part that activates the receptor. Research stores almost always sell kisspeptin-10, molecular weight 1302.4.

Is kisspeptin banned in sport?

Yes. WADA's 2026 Prohibited List names kisspeptin and its agonist analogues under S2.2.1, testosterone-stimulating peptides in males, banned in and out of competition.
