Is BulkGLP legit?
BulkGLP scores 6.49 out of 10 (Fair, #48 of 100) as of November 6, 2026 and passes our testing gate: 12 of the 13 products we score carry a certificate, 12 confirmed with the issuing lab (a lab we grade A). Its strongest area is lab testing (7.5/10); its weakest is operating history (2.6/10), with over a year of records.
On lab evidence, the heaviest-weighted factor, BulkGLP has independently verified third-party COAs, with COA work on record from Freedom Diagnostics Testing. 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 credibility7.5/10
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.

Testing gate: 12 of 13 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.

- Most recent audit · 6.71to6.49
Lab score recomputed under the published rule on 6 November 2026: lab 7.9 to 7.5.
- Audit · 6.72to6.71
Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (StudzPeptides) moved the market median for the same products: pricing 4.8 to 4.7.
- Audit · 6.71to6.72
Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 4.7 to 4.8.
Earlier audits (12)
- Audit · 6.75to6.71
Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (Lotus Peptide) moved the market median for the same products: pricing 5.0 to 4.7.
- Audit · 6.78to6.75
Pricing recomputed on 25 October 2026: listings added for a newly reviewed vendor (Pexo Labs) moved the market median for the same products: pricing 5.2 to 5.0.
- Audit · 6.75to6.78
Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 5.0 to 5.2.
- Audit · 6.77to6.75
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 5.1 to 5.0.
- Audit · 6.80to6.77
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 5.3 to 5.1.
- Audit · 6.57to6.80
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 7.5 to 7.9. Note added 22 October 2026: a score on this entry was corrected from 6.79 to 6.80; it had been rounded down instead of half up.
- Audit · 6.74to6.57
Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 7.8 to 7.5.
- Audit · 6.72to6.74
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 2.2 to 2.6.
- Audit · 8.21to6.72
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 9.5 to 6.5, pricing 9.5 to 5.3, operating history 3.3 to 2.2, transparency 8.5 to 4.5.
- Audit · 7.44to8.21
Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 12 of the 13 products we list that the vendor offers for sale. Lab 6.4 to 7.8.
- Audit · 8.37to7.44
Lab 8.1 to 6.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. The Freedom Diagnostics certificates were read firsthand, not confirmed at the laboratory, apart from one ARA-290 report that we confirmed on the laboratory's site and that shows 53.90% purity. We hold no certificate for the BPC-157/TB-500 blend. The 23 July 2026 entry now says the certificates were read firsthand.
- Audit · 8.18to8.37
Re-audited from live COAs, read firsthand. Every report is Freedom Diagnostics Testing (A-tier), mass-spec confirmed. Notable upgrade: the GLP flagship line now adds endotoxin (USP<85> LAL), microbial PCR, and fentanyl screening on top of purity, so the lab rating was raised. Still no sterility or heavy-metals testing, which keeps it below the top tier.
Editor’s notes
BulkGLP sells retatrutide, tirzepatide and semaglutide alongside BPC-157, TB-500, semax, selank, melanotan II, NAD+, MOTS-c, KPV, ARA-290 and a BPC-157/TB-500 blend. Its site named no operating company at our 22 October 2026 check; the Freedom Diagnostics certificate we read for BPC-157 lists BulkGLP, not an operating company, as the client. Every certificate we read in July 2026 was issued by Freedom Diagnostics and covers MS identity, HPLC purity and content. The GLP-1 products, MOTS-c and TB-500 add endotoxin, a microbial PCR screen and a fentanyl screen. BPC-157, KPV and NAD+ add endotoxin. Semax, selank and MT-2 cover identity, purity and content only. None covers heavy metals; the microbial PCR screen on the GLP-1 products, MOTS-c and TB-500 is counted here as sterility coverage. Purity runs from 98.07% (BPC-157) to 99.92% (NAD+), except one ARA-290 certificate from April 2026, which shows 53.90%; we confirmed that report on the laboratory's own site in October 2026. By October 2026 we had also confirmed the other certificates' Freedom search codes at the laboratory. We found no certificate for the BPC-157/TB-500 blend. In May 2026, US orders shipped same day, free above an order minimum. As of October 2026, 12 of the 13 products we list have a Freedom Diagnostics certificate that we confirmed at the laboratory; we found none for the BPC-157/TB-500 blend, and the ARA-290 certificate shows 53.90% purity.
