Batch traceability is a real feature
Being able to tie a vial back to a specific batch and a specific COA is more important than most suppliers realize. Pepthera built this in by default.

About SS-31
SS31 — also known as elamipretide, Bendavia, or MTP-131 in research literature — is a small synthetic peptide that selectively binds to cardiolipin in the inner mitochondrial membrane. By stabilizing cardiolipin, SS31 has been investigated for its effects on electron transport efficiency, mitochondrial structure, and reactive oxygen species production. Research spans cardiovascular models, age-related mitochondrial decline, primary mitochondrial myopathies, ischemia-reperfusion injury, and Barth syndrome. SS31 is among the most extensively studied mitochondria-targeted peptides in current scientific literature, with multiple clinical trials underway under the name elamipretide by Stealth BioTherapeutics. For research use only. Not for human consumption.

Exceptional purity — exactly what the COA promised
Ordered for a controlled study. HPLC confirmed 99.2% purity. Lyophilised cake dissolved instantly on reconstitution, no cloudiness. Impressed with cold-chain packaging — still at temp on arrival. Will order regularly.

Premium quality for clinical research
Consistently above spec. The purity reading on the COA was independently confirmed by our lab. Cold-chain handling was excellent — vials arrived perfectly preserved.

Quality control presentation felt premium
Tamper-evident seal, batch number printed on the vial, COA tied to that batch by serial — the level of documentation matches what I'd expect from a regulated supplier, not a research outlet. Asked a storage question by email and got a detailed answer in under 3 hours.

Reorder ready
Second order. Same purity, same packaging quality, same fulfillment speed. Predictability matters when planning a research timeline — Pepthera delivers it.

Solid sourcing, would buy direct again
Clean COA, clean reconstitution, accurate fulfillment. Only docking a star because the packaging insert was hard to read in low light — minor critique on an otherwise strong product.
