Loti Labs is a live vendor with a public COA page and real independent test data, but it charges more than most. As of October 19, 2026, Finnrick lists 32 independent tests for Loti Labs, and the site has a dedicated COA page. Most of its per-mg prices are above the median across the vendors in our price index, sometimes by double.
Notice: Loti Labs' 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.

Testing and COAs
Loti Labs has a COA page, and its site says it provides a COA for every batch. What we didn't find: the name of any testing lab, lot or batch numbers shown next to the certificates, and any mention of endotoxin or sterility testing.
Finnrick lists 32 independent tests for the vendor. We don't publish Finnrick ratings, so look up Loti Labs on Finnrick for results by compound.
What we like
- A public COA page and a stated COA for every batch.
- 32 independent tests on Finnrick.
- Same-day shipping is advertised on the site.
- A stated money-back guarantee on unused product.
- No login or age gate in front of the catalog.
What to watch
- Most prices are above the index median; 2mg and 5mg vials are especially costly per mg.
- No testing lab named, and no lot numbers shown with COAs.
- No address, company name or owner published.
- Payment options are limited to Venmo and Cash App.
How it compares
Loti Labs offers more on-site COA disclosure than many vendors, but you pay for it. Check all vendors we track, peptide deals this week and our ranked list before ordering.
Bottom line
Loti Labs looks like an operating vendor with a COA page, outside test data and a refund promise. Its prices are the weak point, and it doesn't name its labs or its company. If price matters, the larger tirzepatide vial is the one item we checked that beats the median.
