Bluum Peptides publishes four separate lab reports for each lot, from named labs. When we checked on October 21, 2026, its product pages showed the current lot with purity, endotoxin, sterility and heavy-metal results, and the site names Janoshik Analytical and BioRegen. It lists an address in Sheridan, WY. We could price only one listing: retatrutide 10mg at $105.00, buy 1 get 1 free until October 22.
Notice: Bluum 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 we checked
| Peptide | Size | Price | Per mg | vs index median |
|---|---|---|---|---|
| Retatrutide (buy 1 get 1 free until Oct 22) | 10mg | $105.00 | $10.50 | 76% above |
Bluum's catalog shows 'from' prices only, so we priced the one listing where we confirmed the size. Retatrutide 10mg at $105.00 is $10.50 per mg, 76% above the median of $5.97 in our price index. Counting the free vial during its BOGO (through October 22, 2026), it's $5.25 per mg, 12% below the median. After the offer ends, compare the retatrutide price index; it also takes 10% off at five or more vials.
It advertises 2-day shipping from the USA.
Testing and COAs
Bluum's documentation is thorough. Product pages show the current lot with four separate reports: purity, endotoxin, sterility and heavy metals. Retatrutide lot RET102609-152I, for example, showed 99.86% purity, endotoxin at or below 0.05 EU/mL (pass), sterility pass and heavy metals pass. A COA lookup page lets you search reports, and the homepage says every batch is tested by Janoshik Analytical or BioRegen.
What's missing is independent data: Finnrick has a profile with no tests. We named the labs as the vendor lists them and didn't verify the reports with the labs.
What we like
- Purity, endotoxin, sterility and heavy-metal reports for each lot.
- Two named labs (Janoshik Analytical, BioRegen) and a COA lookup.
- A listed address in Sheridan, WY.
- A retatrutide BOGO that brings it below our index median while it runs.
What to watch
- Retatrutide 10mg is above our index median once the BOGO ends.
- 'From' prices only, so most of the catalog is hard to compare.
- No company name; a Sheridan, WY address is common for registered-agent services.
- No Finnrick tests yet.
How it compares
Bluum's per-lot testing matches Mile High Compounds and Nura Peptide, the best-documented vendors we added this week. For lower retatrutide prices, see the retatrutide price index and our BOGO deals.
Bottom line
Bluum Peptides is among the best-documented vendors in our directory, with four tests per lot from named labs. Its pricing is hard to judge beyond retatrutide, which is good value during the BOGO and above the median after it. We'll add more prices when sizes are listed.
