Is Loti Labs legit?
Loti Labs scores 7.79 out of 10 (Strong, #12 of 100) as of October 26, 2026 and passes our testing gate: all 25 products we score carry a certificate, 24 confirmed with the issuing lab (labs we grade A-). Its strongest area is shipping and refunds (8.5/10) and its weakest is transparency (3.0/10); its operating history on record covers over seven years. We also record that one posted certificate differs from the laboratory's own copy.
On lab evidence, the heaviest-weighted factor, Loti Labs has independently verified third-party COAs, with COA work on record from Bioviridian, SR Biolabs. Its lowest price per milligram in our data is on GHK-Cu (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 credibility8.4/10
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 25 products: 210.5 ÷ 25 = 8.420.
No adjustments.
8.420 = 8.420, rounded to 0.1: 8.4/10.
Testing gate: 24 of 25 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 · 7.78to7.79
Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (StudzPeptides) moved the market median for the same products: pricing 6.3 to 6.4.
- Audit · 7.79to7.78
Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 6.4 to 6.3.
- Audit · 7.78to7.79
Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 7.0 to 7.2.
Earlier audits (4)
- Audit · 7.91to7.78
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: transparency 5.5 to 3.0.
- Audit · 7.82to7.91
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 7.0 to 8.5, pricing 8.0 to 6.4, transparency 5.0 to 5.5.
- Audit · 7.22to7.82
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 7.3 to 8.4. Note added 22 October 2026: later that day this deduction was replaced by rule A4, under which such a certificate scores 0.
- Audit · 7.49to7.22
Re-audited 2026-10-18 from the live site and the laboratories' own hosts; the May 2026 score was a seed estimate. Lab rises from 6.5 to 7.3: the earlier note said the testing lab was not named, but every current certificate names Bioviridian or SR Biolabs and 24 of 31 match the laboratories' hosted copies, most newer ones with endotoxin screens; the score is held back by seven posted copies that differ from the laboratory's records (one doubled content figure, and six with lot numbers the lab copies lack and later issue dates than those copies), plus a product page linking a certificate for a different blend, a GHRP-6 report with GHRP-2's mass, and no sterility testing. Shipping falls from 10 to 7.0: same-day dispatch, cards and a 30-day unopened return policy are confirmed, but loss and damage are covered only by a paid add-on and the policy treats chargebacks as a breach of its terms. Pricing moves from 7.2 to 8.0 on 22 live standard prices near the market median. Tenure falls from 10 to 7.0: the domain was registered in June 2019, and the site's claim of 14 or more years is not corroborated. Transparency falls from 6.6 to 5.0: no legal entity is named and the address is a suite number.
Editor’s notes
Loti Labs publishes a large certificate library from two independent laboratories. Reports from May to July 2026 come from Bioviridian and include endotoxin screens, a few with heavy metals; older ones, from December 2025 to March 2026, come from SR Biolabs and cover identity, purity and quantity only. No sterility testing is published. We compared 31 posted certificates with the copies the laboratories host, and 24 are identical. Seven are not: the 5-Amino-1MQ report on the site shows double the content recorded in the laboratory's copy, and six May 2026 reports carry lot numbers the laboratory's copies lack and later issue dates than those copies. Separately, the CJC-1295/Ipamorelin product page links a certificate for a different blend. The GHRP-6 report also carries the same retention times as the GHRP-2 report. On 26 October 2026, prices sat about 8% above the market median overall, below it on a few products and well above it on retatrutide, tirzepatide and fragment 176-191. Orders placed before 1 PM Eastern ship the same day from Florida, unopened items can be returned within 30 days, and lost or damaged parcels are covered only with an optional paid protection add-on. Cards are accepted. The site asks visitors to sign in. On 22 October 2026 its footer read 'Powered by Sterling Path LLC' and it listed a Brooksville, Florida mailbox address; the earliest archived capture of the store with prices dates from November 2019.
