| 35 | These are ''nominal'' figures computed from the label claim. The actual concentration depends on the mass of peptide in the vial, which is the product of fill mass, [[Peptide content|content]] and purity — a vial of 5 mg solid at 80% content holds 4 mg of peptide, so the first row is really 4 mg/mL. The [[Reconstitution calculator|calculator article]] carries a working tool; the arithmetic itself is trivial and the difficulty is entirely in knowing the numerator. | 35 | These are ''nominal'' figures computed from the label claim.
