Overview
Fusion Peptide sells research peptides from Glendale, Arizona — the address given on its About Us and Contact Us pages is 6751 N Sunset Blvd Ste 320, Glendale AZ 85305. Its Terms and Conditions name the operator of fusionpeptide.com as Fusion LLC and choose the law of the State of Arkansas; Prof. Peptide reports both statements as the vendor makes them and reconciles neither. The storefront sits behind a 21-plus research-use entry gate, though its policy pages and its certificate library are served without passing it. What sets the catalog apart is format: alongside the lyophilized vials standard across research peptide suppliers, Fusion lists nasal sprays and a reconstitution solution.

Three of these are also sold as nasal sprays — Melanotan II, a Melanotan I / Melanotan II combination, and Selank — and a reconstitution solution and a vial case are listed alongside the compounds. Format is not a category of its own here: the spray products are the same compounds listed above in a different presentation.

Testing: labs and certificates
Fusion publishes a certificate library at fusionpeptide.com/coa which is not behind the entry gate: it returned 200 to an ordinary request on 30 September 2026, and only the homepage redirects to the gateway. Prof. Peptide counted 83 full-size certificate images there on that date, revealed by per-product accordions. That tally is ours rather than a figure Fusion publishes, and because some compounds carry a two-page certificate it counts images, not reports. Two laboratories are named on the documents — Vanguard Laboratory of Olympia, Washington and MZ Biolabs of Tucson, Arizona — and both names are printed inside the certificate images rather than in any page text, which is why nothing on Fusion's own site reads as naming a laboratory. Two certificates were opened and read in full on 14 September 2026: a Cagrilintide 10 mg report from Vanguard giving 99.00% ± 0.18% chromatographic purity by HPLC-UV/VIS, and a TB-500 report from MZ Biolabs giving 99.80% by HPLC-UV-MS on lot ULP-34005. Each figure is the certificate's own reported result, not a Prof. Peptide measurement. One caution from the Vanguard document: its “Lot Number” field reads “Red Cap”, a cap colour rather than a lot, so that certificate cannot be tied to a batch by its own identifier. No accreditation is claimed for these certificates here. Separately, Fusion's Terms publish a Product Quality Guarantee: the vendor states that a buyer may have a product tested at any HPLC-licensed facility and that, if the results are negative, it will refund the cost of the test plus the order total and shipping.
Payment and shipping
Fusion's Terms state that prices are listed in US dollars and may change without notice, and that orders must be paid in full before processing and shipment. Accepted payments are given as major credit and debit cards plus select alternatives such as Zelle, Cash App and cryptocurrency, “or other processors as offered at checkout”, each subject to its own provider's rules; no payment-method discount is stated, and card statements are said to show the descriptor “Fusion Research Supplies USA”. On shipping the published detail is thin: the Terms name no carrier, no dispatch time, no origin and no free-shipping threshold, and Fusion runs no separate shipping policy page. What they do say is that all purchases are final and returns are not accepted; that a shipment arriving damaged may be replaced or refunded at Fusion's discretion; and that Fusion is not liable for delays or delivery failures outside its control, including carrier issues, customs holds and lost packages.
Customer service
Fusion lists an email address, a telephone number and a contact form: info@fusionpeptide.com, 1 800-385-6689, and the form on its Contact Us page. Its stated hours are Monday to Friday 10:00 AM to 6:00 PM MST and Saturday noon to 4:00 PM MST, closed Sunday, and the Contact Us page adds that the best way to reach Fusion outside those hours is the support email. No live chat is listed, nothing on the page indicates whether a human or a bot answers first, and no response-time commitment is stated.
