Common questions
Everything researchers ask before ordering.
Can’t find what you’re looking for? Get in touch.
Are you actually US-domestic?
Yes – every step. Our peptides are synthesized, lyophilized, tested, stored, and shipped entirely within the United States. No international transshipment, no customs handoffs, no overseas drop-shippers. Orders ship from our US facility with full tracking.
How is purity verified?
Every batch is tested by an independent lab using HPLC for purity and LC-MS for identity. The COA is stamped with the batch number, test date, and lab name and uploaded to the product page before any vial from that lot ships.
What documentation comes with my order?
Every vial ships with a tamper-evident seal and a packing slip referencing the batch ID. The matching certificate of analysis — including HPLC purity, LC-MS identity, and endotoxin results — is available on the product page and in your account downloads.
How fast do orders ship?
Orders placed before 2 pm CT ship the same business day. Standard delivery is 2–4 business days. Free US shipping on orders over $300.
