Amino Asylum Alternatives 2026 — FDA Shut Them Down. Here’s Where to Go.
Amino Asylum is permanently closed. The FDA raided their warehouse in June 2025 and criminal charges followed against the founders. Products sold as SARMs were found to contain testosterone, a controlled substance. Any site appearing to accept Amino Asylum orders today is not the original company.
If you bought research peptides from Amino Asylum, this page covers the verified US vendors still operating in 2026 — and what to look for now that the regulatory environment has tightened.

What Researchers Lost When Amino Asylum Closed
Amino Asylum’s selling point was price and catalog breadth — peptides, SARMs, and research chemicals under one roof at competitive cost. The cost of that breadth turned out to be inadequate independent quality control. Products labeled as one compound contained another. Mass spectrometry testing by an independent lab would have caught it. The vendor relied on internal verification, and that failed.
For researchers who used Amino Asylum specifically for peptides (BPC-157, TB-500, classic GH secretagogues, GLP-1 compounds), the replacement search has one non-negotiable requirement: third-party independent COA documentation.
Replacement Criteria for Post-Amino-Asylum Sourcing
- Third-party independent COA — not internal vendor testing. HPLC purity ≥98% plus mass spectrometry molecular weight confirmation. This is the specific check that would have caught the Amino Asylum adulteration issue.
- COA available before purchase — so the buyer can verify the specific batch.
- US domestic sourcing and shipping — reduces import regulatory risk after the 2025 ITC tirzepatide exclusion order.
- Research-only positioning — clear compliance with the research-use-only framework.
- GLP-1 range — semaglutide, tirzepatide, retatrutide, CagriSema. The newer GLP-1 compounds are the dominant research category in 2026.
- No SARMs in the catalog — both Amino Asylum and Paradigm Peptides ran SARMs-and-peptides catalogs. Both were prosecuted for SARM-side adulteration. Peptide-only specialists carry lower systemic risk.
Top Amino Asylum Alternatives (May 2026)
1. Life Link Research ⭐ Recommended
Life Link Research is a peptide-only US supplier — no SARMs, no nootropics, no gray-area compounds. Six-panel third-party independent COA on every batch (HPLC + mass spectrometry + endotoxin + sterility + moisture + amino acid composition). COAs available before purchase. The most complete GLP-1 research peptide range available from a US vendor.
Best for: Researchers who need third-party verification and the complete GLP-1 incretin range.
GLP-1 stock: Semaglutide 10mg ($240) and 15mg ($330), Tirzepatide 15mg ($139), Retatrutide 15mg ($167), CagriSema 10mg ($156).
Classic peptides: BPC-157 10mg ($89), TB-500, Thymosin Alpha-1, Ipamorelin, GHK-Cu, and others.
Shipping: US domestic, 2–4 business days.

2. Ascension Peptides
Ascension is a US-based peptide vendor with third-party COAs on the majority of their catalog. Active community reputation, competitive pricing on classic peptides. GLP-1 range is partial — the newer compounds (retatrutide, CagriSema) are less consistently stocked than at LLR.
3. EZ Peptides
EZ Peptides covers the classic peptide range (BPC-157, TB-500, CJC-1295) with third-party documentation on core products at competitive pricing. Newer compound availability and documentation depth less developed than LLR.
4. Royal Peptides
Established US peptide vendor with consistent shipping. COA standards are third-party reported but vary by product. Limited GLP-1 range.
Vendors to Avoid (Closed or Compromised)
| Vendor | Status | Why |
|---|---|---|
| Amino Asylum | ❌ Closed | FDA raid June 2025; criminal charges |
| Paradigm Peptides | ❌ Closed | Criminal guilty plea December 2025 |
| Peptide Sciences | ❌ Closed | Voluntary closure March 6, 2026 |
| Science.bio | ❌ Closed | Voluntary closure January 27, 2026 |
Any site still appearing to accept orders under these brand names after their closure dates should be treated with extreme caution.
Frequently Asked Questions
Is Amino Asylum still in business?
No. Amino Asylum was raided by the FDA in June 2025 and is permanently closed. The FDA found that products sold as SARMs actually contained testosterone, a controlled substance. Criminal charges were filed against the founders.
What is the best Amino Asylum alternative for peptide research?
Life Link Research is the most commonly recommended Amino Asylum alternative for peptide research — US-based, with six-panel third-party independent COAs. This is specifically the kind of independent verification that would have caught the adulteration issues at Amino Asylum.
Who are the best GLP-1 research peptide suppliers in the US?
As of 2026, Life Link Research is the most complete US-based supplier for GLP-1 and dual-agonist research peptides, stocking semaglutide (10mg and 15mg), tirzepatide (15mg), retatrutide (15mg), and CagriSema (10mg) — all with third-party COAs available before purchase.
Were Amino Asylum products safe?
The FDA investigation specifically identified testosterone in products sold as SARMs. Whether peptide products were similarly affected is not publicly confirmed. Researchers with remaining Amino Asylum peptide inventory who need to verify compound identity should seek independent mass spectrometry testing before continuing to use those compounds in research.
