Full methods/AOD-9604: identity card and what usually goes wrong

Sample requirements

• One sealed, unopened vial, with its label intact. Opened vials cannot be tested because the contents may have changed.
• A clear photo of the label and batch code before you send it.
• Any label amount can be tested.
• Tell us where you bought it. The vendor name stays private unless you choose a public record.

What a AOD-9604 test often catches

• AOD9604 versus AOD9401: one tyrosine apart.
• Reduced, open-chain material instead of the ring.
• Disulfide-linked dimers and oligomers.
• Incomplete side-chain deprotection on a 16-residue chain.
