What we found at Panda Peptides
Read 25 October 2026 on the vendor's own pages
The review record is real and readable. Trustpilot shows 4.7 across 85 reviews on a claimed profile, 92% five-star, and the vendor's own reviews page sends readers to Trustpilot as the primary source rather than quoting a private widget. The one-star review from October 2026 is a return dispute, and the vendor replied. Two things to keep in mind. Semaglutide, tirzepatide and retatrutide sell as 'Single', 'Double' and 'Triple Receptor Agonist'; the compound names appear on the vendor's older Janoshik reports, but you buy under the code name. And Finnrick, which buys and tests independently, has no page for this vendor yet, so there is no independent purity record beyond the vendor-commissioned reports. Ten of ten, tied with Purgo Labs and the other top-band vendors on the same rubric; Purgo is our affiliate partner and Panda is not, and the score does not read that..

Purgo Labs: the caveat
Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Panda Peptides: the caveat
Semaglutide, tirzepatide and retatrutide are listed as 'Single', 'Double' and 'Triple Receptor Agonist'; the compound names appear on older Janoshik reports (e.g. #99315 'Semaglutide 5mg') but the current product pages use the code names.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Panda Peptides. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 7 of 16 like-for-like vials.
A tie on evidence — both earn 10/10. What separates them is review base (4.7 (85 reviews) vs 4.8 (101 reviews)) and price (13 rows cheaper at Panda Peptides, 3 at Purgo). Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is Panda Peptides legit?
Panda Peptides scores 10/10 on our rubric, has an independently viewable rating of 4.7 (85 reviews), and names its lab (Janoshik Analytical · ILS Labs (per batch)). Caveat: Semaglutide, tirzepatide and retatrutide are listed as 'Single', 'Double' and 'Triple Receptor Agonist'; the compound names appear on older Janoshik reports (e.g. #99315 'Semaglutide 5mg') but the current product pages use the code names. The Janoshik BPC-157 report we checked measures 11.56 mg on a 10 mg label, 116% of label, above our 115% line. The Fair Oaks address carries a suite number that reads like a mailbox suite. Finnrick has no vendor page. The one-star Trustpilot review (October 2026) is a dispute over a return; the vendor replied. Reddit coverage is mostly a ranking site's subreddit (r/peptidebenchmark), which runs vendor spotlights.
Which is cheaper, Purgo Labs or Panda Peptides?
On the 16 compound-and-size rows where we have dated prices from both, Panda Peptides lists lower on 13 and Purgo Labs on 3. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders; we earn nothing from Panda Peptides. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
