Biolinx Labs Review: COAs, Pricing, and Identity Conflicts
We checked Biolinx's complete public catalog and 24 Accumark reports, including below-specification purity results, conflicting identities and actual BOGO terms.
We reviewed Biolinx Labs, its complete public catalog, published certificates and anonymous merchandise-cart totals on October 30, 2026. The laboratory documents are independently checkable. They also contain findings that a blanket purity claim or a storefront badge would miss.
PeptideBenchmark may earn commission through the Biolinx referral link or PEPTIDE10. The evaluation is independent; affiliate status does not change evidence scoring. We did not purchase or independently test a vial. Products are labeled for laboratory research only, not for human consumption. This review evaluates commercial transparency and documentary evidence.
What the documents establish
The COA library displayed 20 reports when reviewed. Reading every size-specific product page identified four additional reports: GLP-3R 30 mg, GLP-1S 10 mg, GLP-2T 30 mg and the BPC-157/TB-500 20 mg blend. All 24 reports name Biolinx Labs. Each source PDF matched the corresponding PDF independently downloaded from Accumark’s verification service, with matching report code, lot, measured quantity and purity. An unknown-code control did not return an authentic report.
Reports cover the tested sample and printed nominal strength. A 10 mg report does not cover an untested 30 mg option. A linked certificate also cannot resolve contradictory descriptions of which molecule the storefront sells. We distinguish laboratory document verification, the vendor’s attachment of that document to a product, and an exact compound-and-strength match.
The reported overall purity results range from 92.35% to 99.92%, averaging approximately 98.93% across these 24 reports. The IGF-1 LR3 report (3W26-97U8) prints 95.07%, and CJC-1295 DAC (Y6VM-KY78) prints 92.35%, against the laboratory’s greater-than-98% specification. Both remain in the archive and evidence summary. The laboratory’s negative status percentages are relative differences from its specification, not percentage-point differences.
Measured content is a separate result. For example, the Melanotan II certificate prints 8.9 mg against a nominal 10 mg, 89% of the nominal amount in that assay. Net-content results require context about salt form and analytical method; they do not by themselves establish physical underfilling. Blend certificates include separate component results; their overall purity and total quantity must not be substituted for every component’s purity or content.
Four reports—GHK-Cu 50 mg, Tesamorelin 10 mg, GLP-3R 10 mg and GLP-2T 30 mg—also report endotoxin results and rapid PCR screening. PCR screening is not compendial USP <71> sterility testing. No heavy-metal panel was observed in this collection. A report’s date and lot remain relevant when evaluating what it says about currently sold inventory.
The strongest evidence is the laboratory-confirmed report collection under the vendor's own name. The main limitations are incomplete exact catalog coverage, unresolved product identity fields, the two below-specification purity results and limited additional testing panels. Authenticity of a report does not establish that every listed product or strength has been tested.
Prices and withheld identities
The census includes 41 size-specific products across 28 families, plus 26 multi-product bundles. We publish 36 single-vial list prices across 24 comparison groups. Reconstitution water and multi-compound bundles are retained in the census and excluded from those vial comparisons. No ready spray, capsule/tablet or IU-dosed product was found in this catalog.
These three prices are withheld pending clarification:
- TB-500 10 mg: the product describes the Ac-LKKTETQ fragment while its linked laboratory report declares full thymosin beta-4.
- GLOW 70 mg: the FAQ identifies the Ac-LKKTETQ fragment while the component formula and molecular weight describe full thymosin beta-4. Its purchase selector also says 50MG instead of 70 mg.
- KLOW 80 mg: its purchase selector says 50MG instead of 80 mg. The formula and molecular weight assigned to its stated Lys-Pro-Val component do not match that identity; FDA’s KPV chemistry table distinguishes the free peptide and acetate form.
CJC-1295 DAC 5 mg is included. Its formula, approximately 3,647 g/mol molecular weight, DAC-linker description and laboratory report support the DAC identity. CAS 863288-34-0 is ambiguous/deprecated in public records and does not establish a non-DAC conflict by itself. The structural distinction is documented in FDA’s chemistry table and PubChem’s DAC record. Its 92.35% purity result remains visible.
BPC-157/TB-500 10 mg and 20 mg are included in the fragment-blend lane. Their product FAQs explicitly identify Ac-LKKTETQ (residues 17–23). Prices compare the published total blend mass; the storefront does not publish nominal component proportions, so we do not imply a particular ratio. Their laboratory reports name TB-500 without establishing fragment versus full-length identity, so the documents remain verified without receiving exact fragment-identity coverage.
The vendor’s GLP-1S, GLP-2T and GLP-3R names map to semaglutide, tirzepatide and retatrutide using the published CAS identifiers and laboratory documents. Other available strengths without reports retain their listed prices without receiving unsupported testing coverage.
BOGO and PEPTIDE10
The confirmed referral link reaches the official storefront. PEPTIDE10 was accepted for partner attribution, but the store said: “Code not used on BOGO orders.” The charged coupon discount remained $0, even when a separate field showed a hypothetical nominal percentage discount.
Buying one, two, three or ten BPC-157 vials produced one additional free vial per order, rather than a repeating two-for-one ratio. The public terms allow a free eligible vial of equal or lesser value. Our comparison prices use the single-vial list price; they do not apply an unlimited BOGO discount, assume mixed-basket savings, or combine subscriptions, compare-at prices and coupon percentages. Confirm the current cart terms before relying on a promotion.
We retain exact product-page links. Only the supplied homepage referral route was verified; an unsupported product deep-link parameter is not invented.
Shipping and current profile
The shipping policy advertises domestic delivery to all 50 states, FedEx 2-Day at $19.93, and free delivery above $200. Its noon Eastern business-day cutoff and delivery estimates are vendor statements, not independently tested fulfillment performance. No precise business or fulfillment address was established from the reviewed pages. Research-compound returns are restricted; damaged, missing or incorrect orders have separate claim conditions.

Common questions
Can Biolinx Labs reports be checked at the laboratory?
Yes. On October 30, 2026, all 24 published reports matched the independently acquired Accumark laboratory PDFs byte for byte, with matching Biolinx Labs client, sample code, lot, purity and measured quantity. That verifies the documents, not every vial or every product strength.
Does every Biolinx product have an exact matching report?
No. Exact compound-and-strength matches covered 19 of 67 catalog entries, including 41 size-specific products and 26 multi-product bundles. Three prices remain withheld for concrete identity or strength conflicts. Two fragment-blend prices are listed using total blend mass, but unqualified TB-500 wording in their reports does not establish exact fragment testing.
Does PEPTIDE10 give an extra 10% off BOGO orders?
No additional percentage discount applied in our anonymous carts on October 30, 2026. The code was accepted for partner attribution, but the store explicitly suppressed its discount during BOGO. One, two, three and ten paid vials each earned only one free vial per order.
Is PeptideBenchmark affiliated with Biolinx Labs?
Yes. PeptideBenchmark became a disclosed affiliate on October 30, 2026 and may earn commission through its referral link or PEPTIDE10. This relationship does not affect testing conclusions or scores.
