Are Amino Asylum coupons still working?

No. Amino Asylum has been offline since the June 18, 2025 FDA enforcement action at its warehouse (source). Any “AA20”, “ASYLUM10”, “FREESHIP”, “BLACKFRIDAY”, or other historical Amino Asylum codes you may have saved in a password manager or seen on a coupon aggregator site will not redeem because the storefront is not accepting orders.

The same applies to coupon codes promoted on aggregator sites (RetailMeNot, Honey, CouponBirds, Knoji, etc.) — those listings have not been updated to reflect that the brand is offline. Treat any active-looking AA coupon as stale.

Use this instead: WELCOME20 at Pure Chain Aminos

Pure Chain Aminos is offering displaced Amino Asylum customers a one-time first-order discount:

WELCOME20

20% off your first order. $75 minimum.

Frequently asked questions

Why are old Amino Asylum coupons showing on aggregator sites?

Is WELCOME20 stackable with other PCA promotions?

Does WELCOME20 apply to shipping?

WELCOME20 takes 20% off the subtotal of qualifying products. Shipping, taxes, and any non-product line items are calculated separately.

Can I use WELCOME20 on a second order?

Is there a minimum on the qualifying SKUs?
