Where to Buy SS-31 in the UK

Buying SS-31 in the UK

Buying SS-31 in the UK is rarely a question of availability. Its unusual amino acid composition, including D-arginine and dimethyltyrosine, makes it harder to synthesise than its short length suggests.

The suppliers below are ranked on documentation first and price second. Identity-verified companies with batch-matched analysis sit above cheaper listings that publish less, because on this compound the cheaper listing is usually cheaper for a reason.

What to check before ordering

• • Non-standard residues mean cheap synthesis routes produce close analogues that pass a loose purity check.
• • Peptide content stated per 10mg vial, separately from gross weight
• • Batch number on the certificate matches the number on the vial label
• • A batch-matched certificate of analysis (HPLC purity and mass-spec identity).
• • ID verification — we confirm the trading entity behind the website.
• • Independent reviewer feedback on dispatch speed and packaging.
• • Price per mg rather than price per vial.
