Is Curo legit?
Curo scores 6.27 out of 10 (Fair, #54 of 100) as of November 5, 2026 and does not meet our testing gate: all 8 products we score carry a certificate, 1 confirmed with the issuing lab (a lab we grade B+). Its strongest area is shipping and refunds (7.5/10); its weakest is operating history (1.3/10), with about seven months of records.
On lab evidence, the heaviest-weighted factor, Curo has no third-party testing we could independently verify, with COA work on record from BT Labs, ILS Laboratories. The testing gate applies because that testing could not be independently verified (Third-party testing not established); its limit for Curo is 6.50, and this score is already below it. 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 credibility7.0/10
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 8 products: 56.0 ÷ 8 = 7.000.
No adjustments.
7.000 = 7.000, rounded to 0.1: 7.0/10.
Testing gate: 1 of 8 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is fewer than half, so the testing cap applies (see the methodology).

We compared Curo’s current single-vial prices on 8 products, each matched to the same product and milligrams per vial, with the median price of the other vendors. Its typical price (the median ratio across those products) is 50% above the market median (ratio 1.50), which the published scale maps to 3.5/10. checked

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.

Pricing re-checked on 5 November 2026 after the market medians were recalculated pricing 3.9 to 3.5.

Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 4.2 to 4.4.
- Audit · 6.40to6.37
Pricing recomputed on 23 October 2026 from current listings with the published rule (section E), after listings added or updated since 22 October, including a newly reviewed vendor's, moved the market median for the same products: pricing 4.4 to 4.2.
- Audit · Verified, no change
Re-scored on 22 October 2026 under version 2 of our published rules. No score change. The testing gate is now computed from the certificates instead of set by hand: 1 of 8 products have a certificate from a directory laboratory with the key confirmed at the laboratory, fewer than the half required, so the testing cap applies; the cap sits above the weighted score, so it does not lower it.
- Audit · 6.28to6.40
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 6.0 to 7.5, pricing 5.5 to 4.4, operating history 2.5 to 1.3, transparency 5.5 to 6.5.
- Audit · 6.17to6.28
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: an earlier document-quality deduction that is not part of the published rubric was removed. Lab 6.8 to 7.0.
- Audit · Verified, no change
No score change. Third-party testing is now shown as not independently verified, because confirming a certificate with the laboratory requires submitting a name and email and none of the listed products has a key we could check. The overall score is unchanged because the testing cap sits above Curo's score. The public notes now date the October 2026 catalogue reduction.

lab 6.8 / shipping 6.0 / pricing 5.5 / tenure 2.5 / transparency 5.5.
Editor’s notes
Curo publishes its certificates openly, grouped by production lot, and the documents are better built than most. They cite USP methods by chapter rather than naming a technique loosely, describe the actual vial received, name the upstream manufacturer of the material, and say in plain terms what the testing does not cover. The lot table is also deposited as a citable dataset with a DOI, which is a level of record-keeping no other vendor here matches. Two things hold the rating down. The laboratory does not publicly document accreditation, and checking a certificate with the lab rather than through Curo's own copy requires handing over a name and email, so independent confirmation is gated. A small number of published certificates also carry errors, including one endotoxin report whose manufacturer field reads 'Error 2023' and two bacteriostatic water certificates that repeat another record's content. The catalogue is small and shrank in October 2026: four compounds listed at our 2026-10-04 audit returned a missing page on 2026-10-07, leaving eight peptides plus bacteriostatic water and consumables. Pricing sits above the market median across the range. Products display a struck-through higher price alongside the current one. As of October 2026, all 8 peptide products we list have a current certificate in Curo's lot library, mostly from BT Labs, whose lab-side lookup asks for a name and email, plus one ILS report for KLOW that we confirmed at the laboratory.

Curo: Frequently Asked Questions
Is Curo legit?
Curo scores 6.27 out of 10 (Fair, #54 of 100) as of November 5, 2026 and does not meet our testing gate: all 8 products we score carry a certificate, 1 confirmed with the issuing lab (a lab we grade B+). Its strongest area is shipping and refunds (7.5/10); its weakest is operating history (1.3/10), with about seven months of records.
Is there a Curo promo code, coupon code, or discount code?
We do not have a verified Curo promo code or coupon code right now. When Curo runs a sale or issues a discount code, we post it here and on our promos page, so bookmark this page for the latest Curo discount.
Does Curo use third-party lab testing?
Not to our verification standard. Fewer than half of this vendor's scored products have a certificate from an independent laboratory in our directory (not tier D) whose verification key we confirmed at that laboratory, so the testing gate applies. This records what we could verify; it is not a finding of a quality or safety problem. Laboratories on the certificates we hold: BT Labs, ILS Laboratories.
Where can I see Curo's COAs?
In the "Curo COAs and lab test results" table on this page. We hold 9 certificates for Curo, covering 9 of the 9 products we track, issued by 2 laboratories (BT Labs, ILS Laboratories). 1 product's certificate was confirmed at the issuing laboratory itself. Each row links the certificate, its lab, its test date and the purity it reports.
What peptides does Curo carry?
Curo carries Epitalon, KLOW, KPV, Pinealon, Selank, Semax, TB-500, NAD+, and 1 more. Current per-milligram pricing, COA links, and verification keys for each are in the comparison table on this page.
Is the Curo review on Peptide Source Review affected by affiliate status?
No. All affiliate relationships are publicly disclosed and never change a vendor's score, rank, or gate status. Our scoring formula is published in full and applied identically to every vendor.
