Basically every lab running metabolic studies runs into the same headache — inconsistent peptide quailty tanks your dose-response data and you end up wasting weeks chasing bad batches.
What we've done is skip the middleman completely so you're not paying for the same 99.7% purity that's verified by HPLC and mass spec (usually takes about 20 days or so form order to your UK lab).
The comes in sealed 10-vial boxes and you'll want to store it at -20°C away from light, though honestly most buyers go with the 10mg vial size for easier handling during reconstitution.

But here's the thing — our company can customize the labeling or vial sizes, even bulk synthesis if your protocol needs something different than the standdard 225H348N48O68 molecular formula.
though: it's strictly for research purposes, not for any human use, and molecular weight sits at 4813 g/mol which matters when you're calculating exact concentrations for your assays.
We usually have stock in our UK warhouse, but confirm lead time for custom orders because we don't always have every concentration on hand ready to ship.
The MOQ is one box of 10 vials. If you need larger quantities, let us know and we can discuss bulk pricing.
Yes, we provide a COA for every batch that confirms the ≥99.7% purity and includes HPLC test results.
We ship factory direct, so lead time is usually 5-10 business days to the UK depending on customs clearance.
We offer standard 10 vials per box, but for large orders we can discuss custom packaging options like fewer vials per box.
Store it at -20°C and protect from light. Once reconstituted, use immediately and don't freeze the solution.
