Gonadorelin vs HCG: prices, identity and regulatory status (2026)
Gonadorelin and HCG are compared here as separately listed products. HCG's exact identity is not resolved to a public chemical record here, so this page does not state how the two relate chemically; Gonadorelin is a 10-amino-acid peptide (C55H75N17O13). Check each supplier's specification and certificate of analysis. Neither product has a current in-stock price right now. Gonadorelin was FDA-approved but every application is discontinued; HCG shares its active ingredient with an FDA-approved prescription medicine.

Questions
Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price, except that the labelled featured partner, LA Peptides, is pinned first; “Cheapest” always marks the lowest price.
