We're sitting on about 50 boxes of the 10mg vials and 30 of the 5mg right now, and shippng takes roughly 3-5 working days to most UK postcodes with our cold-chain courier — it's a pain to handle but neccessary for the lyophilized powder.
Basically, researchers who need to study GLP-1 and GIP receptor pathways hit a wall when they can't get consistent peptide quality, so we've set up a UK-based facility with direct HPLC and mass spec on every lot, typically running 99% or better purity across all vial sizes.
molecular weight works out to about 4813 g/mol, and it's a 39-amino acid chain that you'll want to keep at 2-8°C in the dark, because what it does is degrade pretty fast if you leave it out — we've seen that happen with some labs that don't check storage.
Most buyers go with the 10mg vials for initial subcutaneous dosing in animal models, usually starting at 2.5mg once weekly, but the 5mg is better than the 15mg for smaller protocols since it reduces waste.
Also, we don't carry the 60mg vials in stock often — maybe 20 days or so lead time if you need those — and the 30mg size is actually easier to reconstitute than the 20mg for some reason, though neither is pharmaceutical grade for human use since this is strictly for research appliction only.
It's not great for chronic metabolic studies beyond 4 weeks in vivo without a fresh batch because the lyophilized powder loses potency after about 6 months even under proper refrigeration, but that's just the nature of teh peptide.
Our MOQ is one box, which contains 10 vials. You can mix dosage sizes within a box if needed, just let us know when you order.
Standard lead time is 5-7 business days for stock orders. For larger bulk quantities, we may need up to 14 days — we'll confirm when you place the order.
Yes, we include a COA with every order showing ≥99% purity verified by HPLC. Batch-specific docs are available on request.
Keep it at 2-8°C in the original packaging, away from light. Once reconstituted, use immediately — don't freeze the solution.
We offer standard vial sizes from 5mg to 60mg, and packaging is fixed at 10 vials per box. Custom labeling or larger vials are possible for bulk contracts — just ask.
