What 99% pure and a 10% fill actually mean

Two numbers matter on a research vial, and people mix them up.

Purity is how much of the material in the vial is the peptide you asked for. Ours are at least 99% pure. That means at least 99% of the material is that peptide, not leftover junk from making it.

Fill is how much is in the vial compared with the number printed on it. Ours are filled within 10% of the label. A vial marked 10mg holds somewhere from 9mg to 11mg. A vial marked 5mg holds somewhere from 4.5mg to 5.5mg.

Purity does not tell you the fill. A vial can be very pure and still be a little over or under the printed weight. That is what the 10% window is for.

These are research vials, sold one at a time, packed in the USA. They are not a prescription and they are not a pharmacy product. If you have a real prescription, the pharmacy label is the one that counts for that medicine.
