Hacker Peptides has very low prices on the few products we could see, but little testing disclosure. On October 19, 2026, the site named Hot Aminos LLC and showed three products we could match to our index, all priced 55-60% below its median. The site also has a researcher verification gate. We found no COA page, named labs, address or Finnrick tests.
Notice: Products from Hacker Peptides 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 only. 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 we checked
| Peptide | Size | Price | Per mg | vs index median |
|---|---|---|---|---|
| NAD+ (buffered) | 500mg | $26.43 (was $40) | $0.05 | 59% below |
| KLOW blend | 80mg | $51.75 (was $80) | $0.65 | 60% below |
| AOD-9604 | 5mg | $24 | $4.80 | 55% below |
Prices as listed on October 19, 2026. These were the only three of its 14 listed products we could match to our index. All three were far below the median across the vendors in our price index. See NAD+ prices, KLOW prices, AOD-9604 prices and the full price index.
Prices this far below the market are worth a second look. Low prices alone don't tell you anything about quality, and without public COAs or independent tests there is no way to check what's in the vial.
We did not find prices for retatrutide, tirzepatide, semaglutide, BPC-157 or TB-500.
Testing and COAs
The homepage says products are "HPLC purity certified" and "3rd-party tested," and shows a "material / batch / record" section with a link to review testing details. We did not find a certificates page, a named testing lab, lot-matched COAs or endotoxin testing on the pages we could read on October 19, 2026.
We also found no tests for Hacker Peptides on Finnrick. Until a named lab or independent results are available, the purity claims are the vendor's own.
Shipping and support
The homepage advertises free domestic shipping on orders of $250 or more. The site links to a return policy, an FAQ, a contact page and a Trustpilot profile. We did not read a Trustpilot score for this review.
What we like
- A named company, Hot Aminos LLC.
- Very low prices on the three products we could see.
- Markdowns on NAD+ and KLOW.
- Free domestic shipping from $250.
What to watch
- No COA page, named lab or lot-matched certificates found.
- No Finnrick tests found.
- No address or payment methods published on the pages we read.
- Only 3 of 14 products could be priced against our index.
- Prices 55-60% below the median with no independent data to back them.
How it compares
Other vendors in our index pair published COAs and named labs with prices near the median. Hacker Peptides is cheaper on what we saw, with less proof. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Hacker Peptides names its LLC and undercuts the market on the products we could price. It shows no certificates, labs or independent tests we could find. Ask for a lot-matched COA from a named lab before ordering.
