Maximum Peptides had the lowest prices of any vendor we added this week, but almost nothing to verify them with. On October 21, 2026, 31 of the 33 listings we priced were below the median in our price index, many by 40% or more. Its COA page offers a single PDF with no lab named, it publishes no address or company name, and its catalog includes HGH, HCG and SARMs.
Notice: Maximum Peptides' products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Prices as listed on October 21, 2026, before the 10% code. 31 of 33 listings were below the median per mg across the vendors in our price index. Standouts: epitalon 50mg (69% below), MOTS-c 40mg (53% below), NAD+ 1000mg (54% below), semaglutide 20mg (52% below), 5-Amino-1MQ 50mg (47% below) and tirzepatide 100mg (46% below). The two above the median were retatrutide 14mg (7% above) and 5-Amino-1MQ 10mg (87% above). Its CJC-1295 + ipamorelin blend doesn't say whether the CJC-1295 is with or without DAC. Compare retatrutide prices and tirzepatide prices.
Testing and COAs
Maximum Peptides' COA page offers a single downloadable PDF. It doesn't list reports by product or lot, and no testing lab is named anywhere on the site we read. With 77 products and one certificate, there's no practical way to check the batch you'd receive. We found no endotoxin data and no Finnrick profile.
Red flags
Maximum's catalog includes HGH, HCG and SARMs (RAD-140, MK-677, MK-2866 ester), plus enclomiphene and tadalafil capsules. That's a red flag under our scoring, and it means we don't feature Maximum in our deals lists despite its prices.
What we like
- Prices below our index median on 31 of 33 listings, often by 40% or more.
- A sitewide 10% code and free shipping over $175.
- A broad GLP-class range up to 100mg tirzepatide.
What to watch
- One COA PDF for 77 products, with no lab named.
- Sells HGH, HCG and SARMs.
- No address or company name; a new 'Grand Opening' store.
- The CJC-1295 blend doesn't state DAC or no DAC.
- No Finnrick profile.
- Not the same business as the defunct Maxim Peptide, as far as we can find.
How it compares
Maximum's prices beat almost everyone, including Geo Peptides. Vendors that pair low prices with lot-matched COAs, such as PeakForm Peptides, cost more per mg but give you a certificate for your batch. See the price index and all vendors we track.
Bottom line
Maximum Peptides is very cheap, and that's its whole case. With one COA, no lab, no address and HGH and SARMs in the catalog, there's little behind the price. If you try it, ask for the certificate for your exact lot first.
