Black Series Lab is a US-based supplier of premium research-grade peptides, independently HPLC-verified and third-party tested, with a Certificate of Analysis per batch. For researchers replacing Strate Labs, which posted its permanent closure notice on July 1, 2026, the evaluation that matters is not brand familiarity; it is whether a candidate supplier can document what it sells at the analytical level, batch after batch.
Why is Strate Labs gone?
Strate Labs posted a closure notice on its own site on July 1, 2026, citing a regulatory landscape that had "shifted in ways that make it impossible for us to continue operating" as before, without naming a specific action. Separately, the public record shows the company was named a respondent in Eli Lilly's October 2023 ITC complaint over tirzepatide, was found in default on May 15, 2024, and was among the defaulting respondents against which the ITC issued cease-and-desist orders in early 2025, per the Commission's Federal Register notice terminating the investigation; whether that factored into the closure has not been stated by the company. The notice committed to shipping or automatically refunding pending orders, stated that all order history had been removed, and said the site would be taken offline permanently.
The full documented timeline is in our article on the Strate Labs shutdown. Amino Axiom also maintains a sourced editorial deep-dive at aminoaxiom.com/vendor-status/strate-labs. Disclosure: Amino Axiom is part of the same brand network as Black Series Lab, and this article recommends our own store.
What should researchers verify before choosing a replacement supplier?
The 2025-2026 closure wave is the argument for grading suppliers on documentation rather than reputation. The framework:
Batch-specific COA, every batch. The certificate must tie to the production lot you receive. Our COA red flags guide lists what disqualifies a document on sight: missing batch numbers, recycled dates, absent lab identification.
Chromatographic evidence, not just a number. A purity percentage with no chromatogram behind it is marketing. What routine HPLC can and cannot resolve — including the impurity classes it is blind to — is covered in peptide impurity profiles.
Mass spectrometry identity confirmation. Purity and identity are different questions. Mass-spec identity verification explains what a mass match establishes and where its limits are.
Consistency across lots. A supplier willing to show historical batch data across several lots is more credible than one that produces documentation only on request.
Documentation you can retain. Strate Labs removed all order history before going dark. Keep COAs and batch records in your own files, independent of any vendor's account system.
How does Black Series Lab document its catalog?
Every Black Series Lab batch is independently HPLC-verified and third-party tested, with a batch-specific Certificate of Analysis available on request and mass spectrometry identity confirmation. The standard behind that paperwork: premium research-grade material, verified by parties with no stake in the result, with the documentation tied to the specific lot in the vial.
Operations are US-based, and cold-chain handling practices for shipment are covered in our cold-chain shipping article. Everything in the catalog is supplied strictly for laboratory research use.
What does Black Series Lab carry?
The catalog spans the healing, metabolic, GH secretagogue, cognitive, and longevity research categories, each compound page carrying its specifications and documentation. Browse the full catalog to see current availability and pricing.
How do I get started?
Open the catalog, review the documentation on any compound page, and check out with a research-use acknowledgment. If your lab needs historical batch data or has institutional purchasing questions, the site contact form reaches the team directly.
For research use only. Not for human use. All compounds sold by Black Series Lab are intended exclusively as laboratory research materials. Black Series Lab makes no claims regarding the therapeutic, diagnostic, or medicinal use of any product. Purchasers must confirm they are 21 years of age or older and that all materials will be used in accordance with applicable research regulations.
