Look, this isn't for human use—strictly research only, and we're upfront about that because some buyers try to push it beyond that, but for lab work the 99%+ purity is solid and teh HPLC data backs it up batch to batch.
Most buyers here go with the 5mg or 10mg vials—they're easier to reconstitute for dosing in rodent models or cell assays, and the dissolves cleanly if you follow standdard protocols with bacteriostatic water.

We keep stock in Sydney usually, so lead time is 1-5 working days for a single box (MOQ is 1 box, basically 5 vials or so depending on strength), and you can grab 15mg or 20mg if you're running longer-term studies and want to minimize reconstitution frequency.
Storage is straightforward—keep the powder dry and cool before mixing, and after reconstitution it's 2-8°C fridge stable for about 20 days or so, but don't freeze it or you'll lose some activity.

Molecular weight is 4119.6 Da, which matters if you're calculating molar concentrations for your assay—I've seen people mess that up with peptides this size, so check your math if you're doing precise work.
Anyway, we've got COA and HPLC with every order, and the ISO9001 cert means the production line is consistent, but honestly if you're testing for endotoxins or sterility you'll want to verify in-house since we don't guarantee that for research grade.
MOQ is 1 box, so even research-scale orders are fine. We don't offer free samples, but you can start with a single box to test quality.
Lead time is 1-5 working days. Once shipped, delivery to Australia typically takes 5-10 business days depending on the courier.
Yes, we include a COA and HPLC analysis with every order. Our production is ISO9001 certified, so you get full traceability on purity and specs.
Store it at 2-8°C in a fridge after reconstitution. Keep it away from light and use it within a few days for best stability.
We offer standard strengths of 5mg, 10mg, 15mg, and 20mg. Custom strengths are possible for bulk orders, but for single-box research quantities we stick to these options.
