Is LabFirst Peptides legit?
LabFirst Peptides scores 7.73 out of 10 (Strong, #14 of 100) as of October 24, 2026 and passes our testing gate: all 26 products we score carry a certificate, 26 confirmed with the issuing lab (a lab we grade A-). Its strongest area is lab testing (8.9/10); its weakest is operating history (0.7/10), with about two months of records.
On lab evidence, the heaviest-weighted factor, LabFirst Peptides has independently verified third-party COAs, with COA work on record from Kovera Labs. We hold 44 lot certificates in all. Its lowest price per milligram in our data is on NAD+ (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility8.9/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Mean of 26 products: 230.5 ÷ 26 = 8.865.
No adjustments.
8.865 = 8.865, rounded to 0.1: 8.9/10.
Testing gate: 26 of 26 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies.

Audit history and why the rating changed
We re-audit vendors against their live COAs and site. Here is what most recently moved this rating, and why.
See the full score history and chart
- Most recent audit · 7.77to7.73
Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 6.6 to 6.3.
- Audit · 7.55to7.77
Thymosin Alpha-1 re-checked on 24 October 2026. Kovera Labs' own record for the lot now on sale, LF-65B-2609, reports a pass on every test, so the product is scored on that certificate. The failed result Kovera recorded for an earlier lot, LF-65A-2609, stays on record in the product's note. Lab 8.5 to 8.9.
- Audit · 7.57to7.55
Pricing recomputed on 23 October 2026 under the revised rule E1 (standing offers), which prices a size at the lowest total a buyer can pay without a code under standing prices, so a standing offer that includes a second vial at no extra cost now counts at all the milligrams received, in the vendor's own price and in the market medians for the same products: pricing 6.7 to 6.6.
Earlier audits (6)
- Audit · 7.37to7.57
Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 6.5 to 7.5.
- Audit · 7.48to7.37
Re-scored on 22 October 2026 under version 2 of our published rules. Kovera's own record for a Thymosin Alpha-1 lot the vendor presents as passing (LF-65A-2609) reports a FAIL, so the product now scores 0 instead of carrying a separate deduction. Lab 8.7 to 8.5. Score 7.48 to 7.37.
- Audit · 8.04to7.48
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.0 to 6.5, pricing 8.0 to 6.7, operating history 1.0 to 0.7, transparency 8.0 to 7.0. Note added 22 October 2026: a score on this entry was corrected from 7.47 to 7.48; it had been rounded down instead of half up.
- Audit · 7.54to8.04
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed; fixed deductions apply for posted certificate copies that differ from the laboratory's own copy. Lab 7.8 to 8.7. Note added 22 October 2026: later that day this deduction was replaced by rule A4, under which such a certificate scores 0.
- Audit · Verified, no change
No score change. A Thymosin Alpha-1 5 mg lot that was awaiting the laboratory's release at our 14 October audit was later reported by Kovera Labs as not passing, while the copy on the vendor's site had shown passing values. The vendor removed that certificate and withdrew the 5 mg size from sale within two days, and asked the laboratory to re-test the lot. The other 44 certificates match the laboratory's records.
- Audit · Initial audit
lab 7.8 / shipping 8.0 / pricing 8.0 / tenure 1.0 / transparency 8.0. Scored 7.23 on 2026-09-30 and held at the vendor's request for a second batch; the second batch added endotoxin and rapid sterility screening on 24 lots, which raised the lab score from 7.0 to 7.8.
Editor’s notes
LabFirst Peptides publishes a certificate for every size it sells, one per production lot, and holds anything without one off sale. We checked its certificates against Kovera Labs' own records. All 44 current certificates match the laboratory on lot number and purity. A forty-fifth, for a Thymosin Alpha-1 5 mg lot, did not match: the laboratory's record reports that lot as not passing, while the copy on the vendor's site showed passing values. The vendor removed that certificate and withdrew the 5 mg size from sale within two days, and asked the laboratory to re-test the lot. When we checked on 22 October 2026, the lot page for LF-65A-2609 still showed a passing purity figure citing that laboratory record. On 24 October 2026 the lot on sale was LF-65B-2609, which passed every test in the laboratory's own record, so Thymosin Alpha-1 is scored on that certificate; the failed result for LF-65A-2609 stays on record. Purity runs from 99.42% to 99.89%. Lots tested from October onward also carry a measured endotoxin result and a rapid sterility screen, labelled honestly as a rapid screen rather than the fourteen-day pharmacopoeial method, and every lot is screened for fentanyl. Kovera is not accredited, and a few earlier lots measured below their label, most notably retatrutide 10 mg at about 88%. When we re-read prices on 22 October 2026, they sat close to the market median, about 4% above it across the range. Orders placed before noon Pacific ship the same day and shipping is free above an order minimum. Unopened, factory-sealed vials can be returned within 30 days for a refund, damaged or incorrect orders are replaced or refunded, and the company refunds an entire lot if an independent laboratory's result does not match its certificate; no remedy is stated for a lost parcel. It publishes a street address, phone number and named officer. The earliest evidence of the business we found is its domain registration in August 2026, which is what holds the operating-history score down.
