RUO Science's sitewide buy-one-get-one-free makes some prices competitive, but its list prices are high and it doesn't name its lab. On October 21, 2026, 35 of the 44 listings we priced were above the median in our price index before the free vial. It lists a Chicago address, but its struck-through 'regular' prices look inflated and the testing it describes is not tied to a named lab.
Notice: RUO Science's 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.

List prices on October 21, 2026, before the free vial. 35 of 44 listings were above the median per mg across the vendors in our price index; struck-through 'regular' prices were about 1.5 times higher still. With the free vial counted, many items fall below the median: BPC-157 10mg $3.45 per mg (37% below), retatrutide 10mg $4.95 (17% below), tirzepatide 10mg $4.45 (14% below) and tesamorelin 10mg $4.95 (34% below). A few stay above even with BOGO, such as semax 5mg (56% above) and selank 5mg (38% above). See our BOGO deals page and the price index.
Testing and COAs
RUO Science says its products are verified by 'independent third-party laboratories' and lists HPLC, LC-MS, endotoxin, sterility and contaminant screening, with a link to a COA library. On the pages we read, it doesn't name the lab, and we didn't find certificates showing a lab name or lot number. A BOGO means two vials from one lot, so ask for that lot's COA. We found no Finnrick profile.
What we like
- A sitewide buy-1-get-1-free with no limit.
- A published Chicago street address.
- With the free vial, many items fall below our index median.
- A peptides-only catalog, including large GLP-class vials up to 60mg.
What to watch
- 35 of 44 list prices above our index median before the free vial.
- Struck-through 'regular' prices about 1.5x the sale price.
- No testing lab named.
- No company name.
- No Finnrick profile.
How it compares
Among BOGO vendors, Zeptix Labs has lower list prices and names three labs on lot-matched COAs, and Elite Peptides runs BOGO on most of its range. Compare them on our BOGO deals page.
Bottom line
RUO Science can be good value if you use both vials of its BOGO, and it publishes a street address. Its list prices and 'regular' prices are inflated, and the testing it describes isn't tied to a named lab. Do the per-mg math and ask for the lot COA.
