Polaris Peptides
Polaris posts dated batch COAs from named independent labs (AccuMark and Janoshik, HPLC-MS), and they show both the latest and previous results per product, which is rare. They're also unusually honest about actual content versus label: one product literally says 'tested at 7.5mg' on a 5mg vial. Full catalog and pricing are out in the open.
Score Breakdown
Named labs AccuMark Labs and Janoshik; HPLC-MS; latest + previous results per product.
Dated, batch-specific reports with full PDF; purity and history shown.
Latest + previous dated lab reports per product (e.g., 99.03% 2026-06-17; 99.82% 2025-05-14).
Independent Finnrick data (97 samples) shows quality swings by product: tirzepatide A, but retatrutide D across 26 samples, with BPC-157 and semaglutide middling.
Not on reptides; Trustpilot 3.9/5 across 24 reviews, distinctly bimodal (people love it or strongly dislike it).
Phone + email, money-back guarantee, bulk pricing.
Discloses actual tested content (e.g., DSIP 5mg label 'tested at 7.5mg').
Named third-party labs with full PDFs; verified via authenticated session.
Positive Signals
- +Named labs AccuMark + Janoshik

- +Finnrick A-rated tirzepatide and PT-141
- +Transparent about actual tested content
Trust Concerns
Their own paperwork is good, but independent testing tells a more mixed story. Finnrick ran 97 samples and their tirzepatide grades an A while their retatrutide grades a D across 26 samples, which is too many to write off as one bad lot. BPC-157 and semaglutide land in the middle. Trustpilot is bimodal too (3.9 across 24, people either love it or don't). The honest 'tested at 7.5mg' labeling is a plus, but I'd stick to their A-rated products and independently test anything reta.
- !Independent Finnrick testing (97 samples) grades their retatrutide a D across 26 samples, a systemic issue on that product line rather than one bad lot
- !Trustpilot is bimodal (3.9/5 over 24 reviews)
- !Label-vs-content variance disclosed (e.g., 5mg vial 'tested at 7.5mg'), so dosing isn't exactly what the label says
Researcher Notes
- •Named labs AccuMark + Janoshik with dated COAs
- •Finnrick: tirzepatide A, but retatrutide D across 26 samples
- •Trustpilot 3.9/5, bimodal
- •Discloses actual tested mg vs label
- •Quality varies a lot by product, so check the specific compound
