Pure Chain Aminos vs Amino Asylum (Closed): Vendor Comparison and Migration Guide
Last updated: May 2026. A practical, no-fluff guide for former Amino Asylum customers re-sourcing research peptides after the June 2025 FDA enforcement action.
Why this guide exists
Amino Asylum’s storefront has been offline since the FDA enforcement action at its warehouse on or around June 18, 2025 (source: Muscle & Brawn). For research customers who relied on Amino Asylum as a primary supplier, the practical questions are: who do you reorder from, what is comparable, and how do you avoid picking another vendor that exits the market in 12 months?
This page answers those questions specifically for the migration to Pure Chain Aminos.

Three-step migration walkthrough
Step 1: Inventory what you actually reorder
Open your inbox and search “Amino Asylum order”. Pull the last 6 months of confirmation emails and list out the SKUs and dosages. The goal is to migrate your actual reorder list, not the broader catalog you browsed but never bought from. Most research customers have 3-5 core SKUs and a small tail of occasional ones.
Step 2: Match each SKU to PCA equivalents
Use the comparison table above. Most former Amino Asylum customers find direct matches for BPC-157, TB-500, NAD+, MOTS-C, the GH-secretagogue family, and the GLP-receptor research family. The two PCA-specific notes worth knowing:
- GLP-receptor research compounds. PCA carries GLP-3 Receptor and GLP-2-T as research compounds. See the linked research pages for background.
- NAD+ pricing tiers. PCA carries both 500mg and 1000mg vials. The 1000mg works out to a lower per-mg cost.
Step 3: Place the first order with WELCOME20
Build a cart of $75+ to qualify. WELCOME20 then drops 20% off the subtotal. A cart of $75 saves $15; a cart of $150 saves $30; a cart of $250 saves $50. Save the COA PDF from each product page when your order ships.
Reorder cadence and stocking up
If your prior cadence with Amino Asylum was monthly, the consolidation in this market is a reasonable argument for stocking 60-90 days of supply at a time rather than 30. PCA’s catalog is in-stock and the WELCOME20 discount is first-order-only — the math leans toward consolidating your first order rather than splitting it.
What to save from your old vendor
- Order confirmation emails — for SKU/dose history
- Any COA PDFs you previously downloaded — once a vendor’s site is offline, the COA archive is gone
- Credit card statements — for chargeback windows on undelivered prepaid orders

Frequently asked questions
How long does PCA shipping take?
US-based fulfillment with standard domestic shipping. Order cutoff times and delivery windows are listed at checkout and on the shipping policy page.
Does PCA carry every SKU Amino Asylum carried?
PCA carries the high-volume reorder SKUs across the major peptide and nootropic categories: BPC-157, TB-500, NAD+, MOTS-C, the GH-secretagogue family, the GLP-receptor research family, the SS-31 mitochondrial line, and the Semax/Selank nootropic pair. The PCA catalog is not a one-to-one mirror of Amino Asylum’s prior catalog — niche or low-volume SKUs may not be present.
How does PCA pricing compare to what I was paying at Amino Asylum?
Pricing varies by SKU. PCA tends to be competitive on the high-volume SKUs and offers tier pricing on NAD+ (500mg vs 1000mg) and BPC-157 (10mg vs 15mg) where the larger size lowers the per-mg cost. Apply WELCOME20 to your first order for an additional 20% off.
Are PCA COAs from a US lab?
Yes. Third-party HPLC purity testing is performed by a US-based independent lab. Results are published as a PDF on the product page for the lot in stock.
What is PCA’s refund policy?
The full refund and reshipment policy is linked from the site footer. Read it before placing your first order so the terms are clear up front.
A note on the broader market
Two of the most-recommended research peptide vendors exited the market in a seven-month window (Amino Asylum June 2025, Science.bio January 2026). The vendors that remain are those operating in the research-only product class with US-based fulfillment and per-lot documentation. PCA is built on those operational patterns specifically because they correlate with longevity \— not as a marketing claim but as a structural choice about how to run a research peptide business.
