Pro Peptides

We don't rate sellers, so this isn't a yes or no. What the records show, as of Oct 2026: Operating history: online since September 2025. Business registration: Pro Peptides, LLC named; not found in a registry. Regulatory record: no FDA warning letters or recalls found. Testing transparency: supplier's 62 lot certificates; Vanguard named. Other sites using the name: 9 live shops use the name. Each finding links to its source above.

Its contact-information page gives the trade name Pro Peptides and the address Pro Peptides, LLC, 2034 E Southern Ave unit o, Tempe AZ 85282; its about page places it alongside PROSportsMed and Arizona Sports Medicine, and its legal notice says it is operated by PROPeptides and affiliated healthcare entities. Arizona's business search requires a captcha that blocked our automated search, and OpenCorporates holds no Arizona company of that name. OpenCorporates does list a Delaware PRO PEPTIDES LLC and Florida companies named PRO-PEPTIDES LLC and PRO PEPTIDES USA LLC, which we could not connect to this shop. The terms say they are governed by the law of wherever Pro Peptides is headquartered, without naming a state.

Pro Peptides gives its address as Tempe, AZ (unit o) on its own site. Pro Peptides, LLC named; not found in a registry.

We searched the FDA's warning-letter index and openFDA drug enforcement records for the name and the domain and found no action naming Pro Peptides or propeptides.com. We also searched “ProPeptides”, “propeptides”, “Arizona Sports Medicine”, “PROSportsMed” and its supplier, “NorthStar Molecules” (also written as two words), and found nothing naming them; the 25 letters returned for “Pro Peptides” name other companies.

Its certificates page says its peptides come from NorthStar Molecules (NSM) and links to moleculetesting.com, a certificate lookup for that supplier's products, registered in April 2026. Without a login it lists 62 batches for 46 products, each with a lot number and naming Vanguard Laboratory of Olympia, Washington, with test dates from April to September 2026. The four certificates we opened name NSM, not Pro Peptides, as the client, some identify the compound only by a code such as “R10” or “S”, and the shop does not list which lots it sells, so a reader needs the lot on a vial. We did not confirm any certificate with the laboratory.

Nine other live shops use the name: Pro Peptides USA (propeptidesusa.com, registered April 2025), Pro Peptides (propeptides.net, December 2024), Pro Peptides Store (propeptidesstore.com, March 2026), Pro Peptides Direct (propeptidesdirect.com, February 2026, offering pickup in Utah County), Pro-Peptides (pro-peptides.co, July 2026), Pro Peptide (propeptide.ca, shipping from British Columbia), ProPeptide in Dubai (propeptide6.com, also reached from propeptide.com), a Hungarian ProPeptide shop of NaSa Project Kft. (propeptide.net, 2021) and a “propeptide” shop priced in Colombian pesos (propeptide.us). We could not establish whether any of them is connected to Pro Peptides. pro-peptides.com redirects to Fit Aminos, propeptides.co to Biostrategix and pro-peptides.net to a Pinpoint Peptides consultation page. The site this record covers is propeptides.com.
