Amino Asylum is a US-based domestic supplier with limited product depth and US-based markups. PeptidesFromChina.co sources from the same primary manufacturers — eliminating the middleman tier and providing direct access to the synthesis facility.
Amino Asylum acts as a domestic reseller — they import finished peptides and redistribute. PeptidesFromChina.co works directly with the synthesis facility, which removes one full pricing layer. The compounds are the same; the chain of custody is shorter.
Every batch is tested by the manufacturer for purity and concentration as part of routine quality control, using methods such as HPLC and LC-MS. For key compounds, independent third-party lab verification is also available. Amino Asylum's testing varies by batch and compound.
Our catalog includes BPC-157, TB-500, Selank, Semax, GHK-Cu, Epithalon, Semaglutide, Tirzepatide, Retatrutide, CJC-1295 blends, DSIP, NAD+, and 70+ additional compounds. Stock is verified per-order against the live manufacturing facility.
Our platform requires a simple $10 processing deposit after submission — credited to the final invoice. This covers manual stock verification with the facility. No speculative inventory is held. You approve the final confirmed invoice before full payment.
PeptidesFromChina.co ships globally from China. Most research buyers in North America, Europe, and Australia receive shipments within 10–20 business days. Customs documentation is included with every order.
