PureRawz no longer sells products itself. When we checked on September 27, 2026, its site described PureRawz as "an informational and affiliate website" that does "not sell or directly supply the products featured on this website." If you used it for research peptides, the eight vendors we review are compared below. Peptide Plugs (8.1/10) and NextGenPeps (8.0) score highest on our transparency method.

Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice.

What happened to PureRawz

PureRawz was a long-running seller of SARMs, nootropics and research peptides. Three dated events:

September 8, 2025: FDA warning letter. FDA's letter to PureRawz concerned tianeptine products sold as "laboratory and research use only." FDA said website and social media content showed the products were intended for human use.
August 14, 2026: maintenance page. Peptide Warehouse reported that purerawz.co showed a maintenance page with no products listed (dated record).
September 27, 2026: affiliate site. The site listed products again, but its About section said it doesn't sell or supply them and works as an informational and affiliate website.

PureRawz hasn't published a reason for the change that we could find. Our shutdown timeline tracks it alongside the other 2025-2026 closures and FDA letters.

What this means if you ordered from PureRawz

Old links may now go to other sellers. A product page on an affiliate site sends you to whichever vendor it partners with. Check the checkout domain before paying.
Old certificates don't carry over. A COA PureRawz published for its own stock says nothing about a different seller's lot.
Check the new seller from scratch. Run it through the steps in our Peptide Sciences guide: FDA database, lot-matched COA confirmed with the lab, independent data and a published business identity.

Eight peptide vendors to compare

Listed in our editors' order, which isn't sorted by score. Checked September 26, 2026 (Licensed Peptides September 28, 2026). We cover research peptides, including GLP-1-class compounds, but not SARMs or nootropics.

Vendor	Score	Best for	Lab named on site	Ships to	Our code
American Peptides	9.1	Lot lookup, international	Homepage only (Bioviridian)	US and 215 countries	None
NextGenPeps	8.8	Named labs, PayPal	Yes (Janoshik, BioRegen)	US and territories	None
PSPeptides	8.5	Speed, payment range	No (on PDFs)	US, Canada, EU, UK, Australia	CHECKED (10%)
Ascension Peptides	8.1	Lot search, first-order price	Product pages	US only	AFFILIATE50OFF (50% first order)
Peptide Plugs	7.5	Lab-side verification	Yes (Freedom Diagnostics)	US only	None
Swiss Chems	6.5	Long history, overnight shipping	FAQ only (Janoshik)	US and international	None
Licensed Peptides	7.4	Endotoxin reports, 2-day shipping	Yes (Vanguard, Ethos)	US only	Affiliate5 (5%)
Alpha Pro Peptides	6.3	Net content per lot	No (on PDFs)	US only	None

Most verifiable testing: Peptide Plugs gives Freedom Diagnostics accession codes you can look up on the lab's own site.
Lab named on every report: NextGenPeps names Janoshik or BioRegen on each dated COA.
Lowest first order: Ascension Peptides with AFFILIATE50OFF (coupon page).
Longest track record: Swiss Chems, operating since 2018 per its site, though it also has a December 2024 FDA letter and weak Finnrick results.

FAQ

Frequently asked questions

Is PureRawz still selling?

Not directly, by its own account. On September 27, 2026 its About section said PureRawz 'is an informational and affiliate website' and does 'not sell or directly supply the products featured on this website.' Peptide Warehouse reported the site showed a maintenance page with no products on August 14, 2026.

Did PureRawz get an FDA warning letter?

Yes. FDA sent PureRawz a warning letter dated September 8, 2025, about tianeptine products sold as 'laboratory and research use only.' FDA cited website and social media content as evidence of intended human use.

What is the best PureRawz alternative for peptides?

On our transparency method, Peptide Plugs (8.1) and NextGenPeps (8.0) score highest of the eight vendors we review. Both name their testing labs on their own sites. We only cover research peptide vendors, not SARMs or nootropics.

Are the products PureRawz links to tested?

We haven't reviewed the sellers PureRawz now links to. An affiliate site earns from the vendors it recommends, so check any vendor it points you to the same way you'd check a new one: named lab, lot-matched COA, FDA record and business identity.
