Amino Asylum, a research-peptide supplier that built a following among independent researchers, went defunct in 2025. Whether a stopgap supplier was chosen at the time and never formally revisited, or a new search for an Amino Asylum alternative is only starting now because a project is restarting, the vetting process is the same either way: confirm batch-specific third-party testing, dual HPLC and mass-spectrometry verification, domestic United States shipping, and a transparent, fully specified catalog before placing an order. Ascension Labs stocks overlapping categories of research peptides under that documentation standard, and this guide covers what to check, whether this is the first order since 2025 or simply an audit of the supplier used since.
What Happened to Amino Asylum
Amino Asylum stopped operating in 2025, part of a broader wave of research-compound suppliers that exited the market across 2025 and into 2026. For researchers who were mid-protocol at the time, the shutdown likely forced a fast, unplanned supplier switch, the kind of decision sometimes made under time pressure and not necessarily re-examined once a stopgap source was in place. For labs in that position, it is worth treating this as a prompt to formally re-vet the current supplier against the same standard that would apply to a brand-new vendor, rather than assuming the switch made in 2025 remains the strongest option available now.
Why Re-Vetting a Supplier Is Worthwhile, Even a Year Later
The research-compound supply market has continued to shift since 2025, with additional vendor closures reported into 2026. A supplier that was adequate as an emergency replacement is not automatically the best long-term source, and documentation standards have generally become more exacting as researchers have grown more cautious about unverifiable purity claims. A periodic re-audit, checking whether a current supplier still provides a current, batch-specific COA, still uses an independent testing laboratory, still ships domestically, and still discloses full specifications on product pages, is good lab practice regardless of whether the last vendor change was voluntary or forced by a shutdown.
The Vetting Checklist
Whether replacing Amino Asylum directly or reassessing a supplier chosen in 2025, the same four-part checklist applies. Confirm the Certificate of Analysis is batch-specific and issued by an independent laboratory, not a generic or reused report. Confirm it includes both an HPLC chromatogram showing purity and mass spectrometry data confirming molecular identity, since a single purity percentage without supporting raw data is not sufficient documentation. Confirm the supplier ships from domestic United States inventory, which shortens transit time for temperature- and moisture-sensitive lyophilized material and avoids customs uncertainty. Finally, confirm catalog transparency: product pages should list molecular weight, sequence, and lot information, and the supplier should be able to answer direct questions about which laboratory performed testing on a given batch.
Documentation for Any Remaining Inventory
Some labs still have unused lyophilized material that was originally purchased from Amino Asylum before the company went defunct. From a documentation standpoint, any remaining inventory should still be matched to whatever Certificate of Analysis was issued with that original batch, and that record should be kept on file even after the supplier is gone. If the original COA cannot be located, the more conservative practice is to treat that inventory as undocumented for research purposes and rely on newly sourced, fully verified material for any protocol requiring confirmed purity and identity. This is simply an extension of standard lab recordkeeping practice, not a statement about the condition of any specific batch.
Overlapping Categories in the Ascension Labs Catalog
The current Ascension Labs catalog covers many of the same research-compound categories previously sourced from Amino Asylum, including growth hormone secretagogues CJC-1295 and Ipamorelin, the full-length GHRH analog Tesamorelin, tissue-repair research peptides BPC-157 and TB-500, the copper-binding tripeptide GHK-Cu, neuropeptides Selank and Semax, plus PT-141, MOTS-c, and NAD+ for cellular metabolism research. Each product page lists molecular weight and sequence data alongside a current, batch-specific COA tested by Janoshik Analytical, which makes it straightforward to compare specifications directly rather than relying on brand reputation alone, useful whether this is a first order since 2025 or a documentation upgrade on an existing supplier relationship.

Frequently Asked Questions
Is Amino Asylum still operating in any form? No, the company went defunct in 2025, and there is no indication that operations have resumed since.
A different supplier was already chosen back in 2025; is anything else needed? Not necessarily, but it is worth confirming that the current supplier still meets the four-point standard above: independent batch-specific testing, HPLC plus mass-spectrometry verification, domestic shipping, and catalog transparency. Vendor closures have continued since 2025, and a periodic check is reasonable lab practice.
How does a new supplier peptide compare to what was previously used from Amino Asylum? Compare the Certificates of Analysis directly: purity percentage, observed versus theoretical molecular weight, and the identity of the testing laboratory. If those figures match or exceed what was previously on file, the material is a reasonable substitute from a documentation standpoint.
Does Ascension Labs ship domestically? Yes, all orders ship from United States-based inventory.
Where can a Certificate of Analysis be reviewed properly? The Ascension Labs COA page walks through what a legitimate batch-specific COA includes, such as how to interpret HPLC chromatograms and mass spectrometry identity data.
