What SS-31 is
SS-31, developed clinically as elamipretide, is a tetrapeptide that binds cardiolipin in the inner mitochondrial membrane. It has been through multiple clinical trials in mitochondrial myopathy and heart failure, so unlike most longevity-adjacent peptides it carries real human data, mixed though the outcomes have been.
Its unusual amino acid composition, including D-arginine and dimethyltyrosine, makes it harder to synthesise than its short length suggests.
What the evidence base looks like
There is a real published record behind this compound, spread across animal work and a smaller amount of human data, but not enough controlled evidence to support confident claims.
Our library records roughly 96 relevant publications for SS-31 and grades the evidence as moderate. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on SS-31
Non-standard residues mean cheap synthesis routes produce close analogues that pass a loose purity check.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 10mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 10mg vial is £49.90, against a market median nearer £71. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
