BENCHMARK PROFILE
Premier Bio Labs
Latest sync: Sep 8, 2026, 8:55 AM. Source coverage currently reflects PB Evidence data.
Readers who want a wide U.S. catalog with public ILS/Freedom COAs that resolve at the lab, including multi-vial kits compared fairly on a per-mg basis.
Vendor-stated: Premier Bio Labs LLC; contact address 1603 Capitol Ave Suite 413, Cheyenne, WY 82001; TOS mailing address 30N South Gould Street Ste R, Sheridan, WY 82801; free shipping from $150 rewards tier; domestic and international shipping; 1–2 business day processing. Support (307) 370-2330 / info@premierbiolabs.com. Observed August 3, 2026.
GLP-1 SM, GLP-2 TZ, and GLP-3 RT are branded names for semaglutide, tirzepatide, and retatrutide; GLOW/KLOW/Wolverine and several dual-peptide blends are house names mapped to labeled components. Mixed starter packs and accessory SKUs are outside the peptide comparison board. Melanotan-1 and Tesamorelin are hard to price fairly when the vendor lists two possible strengths under one price. Domain registered September 2025 — still a relatively new storefront. Two Wyoming addresses appear in public materials (Cheyenne contact vs Sheridan TOS).
A Wyoming research supplier with a large openly priced peptide catalog, a public COA page, and ILS Laboratories plus Freedom Diagnostics reports that check out at the labs under the Premier Bio Labs name.
Premier Bio Labs sells a broad research-only range — singles, blends, and multi-vial kits — with prices listed on the product pages. Its public COA page and product photos link ILS and Freedom Diagnostics reports; PeptideBenchmark confirmed those reports live at the labs during onboarding. Branded GLP-1/2/3 and house blends (GLOW, KLOW, Wolverine) are mapped from the vendor's own labels.
The public COA page and product galleries link ILS Laboratories and Freedom Diagnostics reports that readers can check on the labs' own verify pages. Safety-panel depth is strong on the current set (identity, HPLC, endotoxin, and often sterility/heavy metals).
This vendor is one of 113 names currently included in our manual curated research-vendor layer.
This is the strongest public transparency pattern on the site. The key signal is that readers can leave the vendor domain and inspect reports or verification pages on an outside provider domain without needing to log in.
- Treat the outside provider route as the strongest part of the evidence, not the vendor marketing copy around it.
- Look for repeated product-level behavior across the catalog, not just one showcase example.
- Do not overread it as proof that every current lot is covered or current unless the linked report trail itself supports that.
This vendor makes the most sense when you compare it to other vendors using a similar transparency model, rather than to every vendor on the board at once.
PB Curated Assessment is a PeptideBenchmark-authored rubric built from the trust and transparency review layer. It is separate from the source-derived benchmark score.
Premier Bio Labs is currently one of the strongest curated cases on the site because readers can inspect a repeatable public evidence trail without logging in.
Readers can leave the vendor marketing layer and inspect verification publicly.
This is the strongest public pattern because the verification step routes into an outside provider layer.
Current review touched 136 products and 72 document/link destinations.
2 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 9.2 from pb evidence score.
PB Curated Assessment: Strong. This is our own trust/transparency rubric and is kept separate from the PB score.
Under the formula retired on Aug 28, 2026 this vendor scores 9.20 — the live evidence-first score is 6.73 (-2.47). What changed and why: scoring methodology.
Observed from public domain records and the vendor's own site on Aug 27, 2026. Identity facts are shown for context and do not affect scores.
Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.

PB score is the number you should read first on this page. It starts with trust evidence, pricing coverage, and third-party review signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available. Reviewed transparency evidence contributes a bounded amount — shown as a trust lift for source-benchmarked vendors, and folded into the base score for PB-evidence vendors.
This vendor’s score is evidence-first: verifiable testing evidence forms the backbone, and outside review sources are a bounded adjustment that can warn far more than it can boost. The terms below sum to the displayed score (small rounding aside). Full formula on the scoring methodology page.
WHAT THIS PAGE IS
- Board-ranked vendor profile with source-linked benchmark inputs
- No Finnrick score currently linked
- No Peptide Critic score currently linked
- Includes Trustpilot review coverage
- No Pep Review Pro profile currently linked
CURRENT LIMITS
- Not an original lab test or editorial review
- Source scales and methodologies differ across sites
- Depends on source site freshness and formatting
These are representative public examples from the vendor testing review queue. They show how product pages in the catalog expose public report or verification paths, but they should still be read as examples rather than proof for every current lot.
In other words: the relationship registry above captures the vendor-to-provider link itself, while the examples below show what that link looks like across real product pages.
METHODOLOGY
How to read this benchmark
This profile summarizes public benchmark data synced from Finnrick and, when available, Peptide Critic. Finnrick contributes a 10-point average from its vendor table, while Peptide Critic contributes a 5-star rating that we normalize to a 10-point scale before ranking consensus entries.
A high score can be directionally useful, but it is not a substitute for current COAs, identity testing, chain-of-custody details, or your own due diligence. We are intentionally separating source aggregation from first-party editorial claims.
Scores combine PB trust evidence with external signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available.
