One vial measured — over-fill beyond 115% is flagged, not rewarded.
Opened from the product page, then looked up on koveralabs.com's verify page on 10 Oct 2026 — the lab served the same certificate. 121% of label (flag line 115%).
A new vendor that did the certificate work properly: a Kovera report per batch, checkable on the laboratory's own site, a named LLC with an address, and payment rails and returns written down. The vial measured 21% over its label, and there is no review record to read because Trustpilot removed the profile. Nine of ten on documentation; the track record is a few months old.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

First, the name: this is purepeptides.com, trading as Pure Peptides and owned by Calibre Labs LLC. It is not Pure Peptide Labs (purepeptidelabs.com), which we cover separately. The two get confused in search and on coupon sites, so check the domain before you rely on either page.
The documentation is the strongest kind on our rubric. Every product page carries a batch-specific Kovera Labs certificate with the batch number printed on the vial. We took the BPC-157 report (KVR-2026-BB7E5F) to Kovera's own verification page and the laboratory served the same certificate from its domain: 99.621% purity by RP-HPLC, identity confirmed by LC-MS, 12.11 mg measured. That last number is the thing to notice. On a 10 mg label it is 121%, over our 115% flag line. An over-filled vial is not a safety finding, and a strong vial is better than a weak one, but a researcher dosing from the label is off by a fifth. The company is named on every page with an address — a Sheridan, Wyoming registered-agent suite, which is a legal address rather than premises, and we say so.
What is missing is history. The about page says the company was founded in 2026; every lot we opened is a June 2026 batch, one per product; and Trustpilot has removed the purepeptides.com profile for a guidelines breach, which may belong to whoever used the domain before — we cannot tell. There is no independent review record to read, so the review-base point is withheld. Nine of ten on what can be checked today, with the honest note that "today" is a few months into the company's life. Prices sit mid-market for 10 mg vials (BPC-157 $51, TB-500 $60), no GLP-class compounds are sold, and the multi-vial discount is 5–10%.
(certified 30 July 2026): purity 99.621% by RP-HPLC against a >98% specification, identity confirmed by LC-MS, measured net content 12.11 mg on a 10 mg label, CAS 1628202-19-6 printed. One vial measured.
Kovera's own verify page returned the certificate for report KVR-2026-BB7E5F from koveralabs.com — same batch, same figures.

Read 10 October 2026. Not to be confused with Pure Peptide Labs (purepeptidelabs.com), a different vendor we also cover. Every product page carries a batch-specific Kovera Labs certificate; the BPC-157 10mg one (batch PP/BPC/062026, report KVR-2026-BB7E5F, certified 30 July 2026) reports purity 99.621% by RP-HPLC against a >98% specification, identity confirmed by LC-MS, and a measured net content of 12.11 mg on a 10 mg label. We entered the report number on Kovera's own verification page and it returned the same certificate from the lab's domain, figure for figure. The company is named on every page with an address: Calibre Labs LLC, trading as Pure Peptides, 1309 Coffeen Avenue STE 20165, Sheridan, WY 82801; the terms say it is incorporated in the United States and the about page says it was founded in 2026. Open catalog of 77 compounds with sized prices (BPC-157 5mg $29 / 10mg $51; TB-500 10mg $60; NAD+ 1000mg $84; GHK-Cu 100mg $98; Ipamorelin 10mg $57; Tesamorelin 10mg $75) — no GLP-class compounds are sold. Cards, bank transfer and cryptocurrency at checkout; 14-day unopened returns.
Trustpilot has removed the purepeptides.com profile ('goes against our guidelines', read 10 Oct 2026); the domain predates the 2026 relaunch, so the removal may belong to an earlier operator, but either way there is no independent review record to read — that costs the review-base point. The measured 12.11 mg on a 10 mg label is 121%, over our 115% flag line: a strong vial, but a vial that does not match its label is still a dosing problem for a researcher. The Coffeen Avenue suite is a Wyoming registered-agent address, not premises; identity is awarded on the named LLC with that disclosure. Every lot we saw is a June 2026 batch — one per product — consistent with a company that started this year. Prices are mid-market for 10 mg vials and the multi-vial discount is 5–10%.

Pure Peptides names Kovera Labs. Certificates resolve on the lab's own system, so a report can be checked with the lab rather than only downloaded from the vendor. Read 10 October 2026. Not to be confused with Pure Peptide Labs (purepeptidelabs.com), a different vendor we also cover. Every product page carries a batch-specific Kovera Labs certificate; the BPC-157 10mg one (batch PP/BPC/062026, report KVR-2026-BB7E5F, certified 30 July 2026) reports purity 99.621% by RP-HPLC against a >98% specification, identity confirmed by LC-MS, and a measured net content of 12.11 mg on a 10 mg label. We entered the report number on Kovera's own verification page and it returned the same certificate from the lab's domain, figure for figure. The company is named on every page with an address: Calibre Labs LLC, trading as Pure Peptides, 1309 Coffeen Avenue STE 20165, Sheridan, WY 82801; the terms say it is incorporated in the United States and the about page says it was founded in 2026.

On our published rubric Pure Peptides scores 9/10 and Purgo Labs 10/10. Purgo Labs is our affiliate partner and Pure Peptides is not; the comparison module on this page shows the criteria each earns and the same vial at both prices, computed from the same dated data.
10mg was $51.00 on 10 October 2026 (5mg $29; batch PP/BPC/062026). Prices move; we record what we saw and when.
