What we can test your peptides for
You bought it. But did you get what you paid for?
Every sample starts with identity, purity, and quantity by HPLC — the core panel that confirms your compound is what the label claims, at the strength you paid for, and free of fillers. From there you can layer on targeted safety screens. Community testing is free for eligible products and samples, subject to publication requirements. Custom testing includes a required Basic fee and any product surcharge.
Add Endotoxins and other options with our Standard testing.
