Salt form on Epitalon
TFA is the default out of synthesis and it is not inert in cell work. If you need a limit, state it before the order — it is a purification decision, not a label.

peptides.
A deliberately short range — four items we will defend line by line, rather than a long list of things that sound similar.
Overview
Four products, not forty.
Four products: Epitalon (the AEDG tetrapeptide) and its N-acetylated form, MOTS-c, and SS-31 (elamipretide). Each has a different mechanism and a different analytical story, and none of them is a commodity.
Epitalon is supplied as the TFA salt by default, because that is what solid-phase synthesis gives; if residual TFA matters for your work, say so and we will quote the salt-free or acetate form. MOTS-c is a 16-residue mitochondrial-derived peptide and considerably harder to make than its price on some marketplaces suggests. SS-31 is a cell-penetrating tetrapeptide that partitions into the inner mitochondrial membrane — related in topic to MOTS-c, unrelated in sequence.
- Epitalon and N-acetyl Epitalon as separate codes
- TFA content declared where the salt form requires it
- MOTS-c supplied with MS identity and net peptide content
- SS-31 held as its own item, never as a synonym for MOTS-c

Specification
What to specify.
Three things decide whether two quotations for the “same” peptide are actually the same material.
Not interchangeable
MOTS-c and SS-31 are both mitochondrial and that is where the similarity ends. Different sequences, different targets, different prices.
Purity against content
A 98% HPLC result on a lyophilised peptide can still be 80% peptide by mass. For anything dosed by molarity, ask for net peptide content.
