Amino Asylum was permanently shut down by the FDA in June 2025. This guide covers the best alternatives for former Amino Asylum customers — including Finnrick Analytics independent lab data, a full Purgo Labs comparison, and guidance on which supplier best matches your research needs.
Amino Asylum Is Permanently Closed (June 2025)
Amino Asylum was shut down by the FDA in June 2025 and is no longer accepting orders. The company is not expected to resume operations. Researchers who previously sourced from Amino Asylum need to find an alternative supplier. Purgo Labs is the most commonly recommended alternative for research-grade peptides with verified purity and US-based fulfillment.
Our Assessment (2026)
Amino Asylum was a well-known research chemical vendor with a broad catalog spanning peptides, SARMs, injectable steroids, and ancillaries. Before its FDA shutdown in June 2025, it had a large following in the fitness and bodybuilding research community. Finnrick Analytics testing showed mixed quality: Semaglutide received an A (Great) rating, most peptides received C (Okay) ratings, and one BPC-157 batch showed a +66.8% overdose — a significant quality control failure. PT-141 received a concerning -2.5 score.
Purgo Labs is the recommended alternative for researchers who need research-grade peptides. HPLC + mass spectrometry dual testing on every batch, a ≥99% purity guarantee, publicly accessible batch-specific COAs, US-based fulfillment, and a 15% discount with code HEALTH make Purgo Labs the strongest available option for the peptide compounds that Amino Asylum previously supplied. For researchers who also need SARMs, Purgo Labs focuses exclusively on peptides.
Before the FDA shutdown, Finnrick Analytics independently tested 15 Amino Asylum samples across 8 products. The data provides the most objective quality record available for this vendor. Overall ratings ranged from A (Great) for Semaglutide to Unrated (concerning score) for PT-141, with most peptides landing in the C (Okay) range.
| Product | Finnrick Rating | Tests | Avg Score | Key Finding |
|---|---|---|---|---|
| Semaglutide | A — Great | 2 | 7.8 | Best result — strong purity and quantity accuracy |
| Ipamorelin | C — Okay | 2 | 5.9 | Acceptable but below top-tier vendors |
| CJC-1295 | C — Okay | 2 | 5.6 | Acceptable; quantity variance across batches |
| Retatrutide | C — Okay | 2 | 5.6 | Acceptable purity; quantity slightly variable |
| Tirzepatide | C — Okay | 2 | 5.8 | Acceptable purity; quantity slightly variable |
| Melanotan II | C — Okay | 2 | 5.3 | Acceptable purity |
| BPC-157 | C — Okay | 2 | 5.2 | ⚠️ One batch: +66.8% overdose (8.34mg in 5mg vial) |
| PT-141 | Unrated | 1 | -2.5 | ⚠️ Significant underdose: 8.08mg of 10mg labeled (-19.2%) |
BPC-157 overdose note: One Amino Asylum BPC-157 batch contained 8.34mg in a vial labeled as 5mg — a +66.8% overdose. While this means researchers received more compound than labeled, it represents a significant quality control failure that undermines dosing accuracy and research reproducibility.

Amino Asylum was popular partly because of its SARM and steroid catalog. Purgo Labs focuses exclusively on research peptides and does not carry SARMs, injectable steroids, or oral compounds.
If your research requires SARMs in addition to peptides, you will need to source from separate vendors. For the peptide component of your protocol, Purgo Labs offers a stronger quality assurance framework than Amino Asylum provided.
Purgo Labs catalog: 30+ research peptides including recovery, growth hormone secretagogues, GLP-1 class, longevity, cognitive, and immune compounds.
One of the more telling details in the Finnrick Analytics data is the absence of batch IDs on Amino Asylum's tested samples. All tested samples were labeled as "White Label / Silver" with "no batch ID" recorded. This suggests that Amino Asylum's products did not carry batch-specific identifiers that would allow researchers to cross-reference a received vial against a specific COA. Without batch IDs, it is not possible to verify that the COA provided on a product page corresponds to the specific production run a researcher received.
Amino Asylum provided COAs on request rather than proactively publishing them per batch. The company's own website described selective third-party testing — meaning not all products or batches received independent laboratory verification. This is a lower documentation standard than what the current market leaders provide.
Purgo Labs provides batch-specific COAs with HPLC + mass spectrometry dual testing on every product, publicly accessible without account creation. The mass spectrometry component confirms molecular identity — not just purity percentage — which is the critical distinction for research applications where compound identity is as important as concentration.

Shop Purgo Labs — Code HEALTH for 15% OffNo. Amino Asylum was permanently shut down by the FDA in June 2025. The company is no longer accepting orders, and its website has been taken offline. Researchers who previously sourced from Amino Asylum need to find an alternative supplier. Purgo Labs is the most commonly recommended alternative for researchers who need research-grade peptides with verified purity, batch-specific COAs, and US-based fulfillment.
Amino Asylum was shut down by the FDA in June 2025 as part of a broader enforcement action against gray-market research chemical vendors. The company had been operating since the mid-2010s and was one of the larger vendors in the research peptide and SARM space. The FDA shutdown was permanent — Amino Asylum is not expected to resume operations. This was one of several major vendor shutdowns in 2025, following the earlier closure of Peptide Sciences in March 2026.
Purgo Labs is the recommended alternative for researchers who sourced peptides from Amino Asylum. Purgo Labs offers HPLC + mass spectrometry dual testing on every batch, a ≥99% purity guarantee, batch-specific COAs publicly accessible without account creation, US-based fulfillment with 3–5 day shipping, and a 15% discount with code HEALTH. For the GLP-1 class compounds (semaglutide, tirzepatide, retatrutide), Purgo Labs has a particularly strong selection. For researchers who also need SARMs, note that Purgo Labs focuses exclusively on peptides.
Finnrick Analytics tested 15 samples across 8 Amino Asylum products before the shutdown. Semaglutide was their strongest result, receiving an A (Great) rating with an average score of 7.8. Most peptides — BPC-157, CJC-1295, Ipamorelin, Melanotan II, Retatrutide, and Tirzepatide — received C (Okay) ratings. PT-141 received an Unrated designation with a score of -2.5, indicating significant quality concerns. One BPC-157 batch showed a +66.8% overdose (8.34mg in a 5mg vial), which is a serious quality control failure regardless of purity percentage.
Amino Asylum's BPC-157 received a C (Okay) rating from Finnrick Analytics across 2 tests, with an average score of 5.2. However, one batch showed a +66.8% overdose — the vial contained 8.34mg when labeled as 5mg. While this means researchers were getting more compound than labeled (rather than less), it represents a significant quality control failure that could affect dosing accuracy and research reproducibility. Purgo Labs provides batch-specific COAs with exact quantity verification on every product.
Yes. Amino Asylum had one of the broader catalogs in the research chemical space, including SARMs (Selective Androgen Receptor Modulators), injectable steroids, oral compounds, ancillaries, and peptides. This broad catalog was a major reason for its popularity in the fitness and bodybuilding research community. Purgo Labs focuses exclusively on research peptides and does not carry SARMs or steroids. Researchers who need both peptides and SARMs from a single vendor will need to source from separate suppliers.
Amino Asylum's pricing was generally competitive within the market — BPC-157 5mg was approximately $38–42, TB-500 5mg approximately $48–55, and Ipamorelin 2mg approximately $25–30. There was no permanent discount code. Purgo Labs' pricing combined with the 15% discount code HEALTH is generally comparable or better on a per-milligram basis, and comes with HPLC + mass spectrometry dual testing on every batch rather than selective testing. Since Amino Asylum is no longer operating, direct price comparison is no longer relevant — Purgo Labs is simply the available option.
