Does the SS-31 name equal a specific milligram fill?

No. The 10 mg and 50 mg fills are separate shop URLs. Match the milligram size on the certificate to the vial. Sold-out status is inventory, not a second sequence.

SS-31, mitochondria-targeted tetrapeptide

SS-31 is a synthetic tetrapeptide in the Szeto–Schiller series, also discussed in the literature as elamipretide. Published descriptions emphasize a short, basic, aromatic sequence and association with cardiolipin in the inner mitochondrial membrane. It is not a mitochondrial open reading frame peptide. MOTS-c is that different class. Length alone separates them: four residues versus sixteen.

For the catalogue pages, see SS-31 10 mg and SS-31 50 mg. A 10 mg report does not document a 50 mg vial, and the 50 mg listing has no published row yet. For the compound note, see What is SS-31?. For the class note, see mitochondrial peptides.
