Actually, we’ve been moving a lot of this lately with custom vial sizes — our company can do 2mg, 5mg, or 10mg straight off the line, but if you need something like 7.5mg or a specific concentration, that’s pretty straightforward to arrange on a bulk synthesis order, and we usually have stock for the standard strengths within 20 days or so.

We’re seeing a lot of interest for 5mg and 10mg vials — most buyers go with the 10mg because of that it gives you more flexibility for dilution, and we’ll label them however you want, no extra charge, as long as the MOQ clears about 500 vials. The CAS is 910463-68-2, purity runs >99.5% by HPLC, and the molecular weight is hefty at C187H291N45O59, which isn’t something you need to worry about day-to-day but helps with reconstitution math.

Now, one thing we hear a lot is concern about stability after you pop the stopper — what it does is hold up fine at 2°C to 8°C after reconstitution, but you really don’t want to leave it out at room temp for more than a few hours, and I always tell researchers to use it within a week or so once it’s mixed, because the peptide chain can start to fray. Also, this is strictly for research use only — it’s not suited for human administration in any form, and we include that on SDS.
The grade is pharmaceutical, which means the tolerance on impurities is tighter than reagent grade, and you’ll get a COA with each batch showing the key specs like residual solvents and endotoxins — we’ve got the TDS on request if you need it for your internal compliance folks. But let’s be real, the real reason people come back is the bulk pricing: we’re competitive because we control the synthesis in-house and don’t have middlemen tacking on margins.

You’ll want to confirm lead time for custom labeling though — we usually turn standdard orders in 2-4 weeks, but if you’re asking for a custom vial size that isn’t one of teh three we keep on the shelf, add maybe 7 days for the fill line changeover. And I’d recommend ordering a little extra if your lab uses a lot of compound, because once we synthesize your batch, we’re locked into that lot for any repeats.

Anyway, just shoot over your RFQ with the vial size, quantty, and any special labeling — we’ll quote you back with an MSDS and COA samples form the last batch, and we can send a prepaid freight quote too if you’re outside our usual zone.
We typically require a minimum of 100 vials per order for the 10mg size, but we can be flexible on larger bulk runs. Let us know your volume and we'll work with you.
Standard lead time is 7-10 business days after order confirmation. Custom labeling or vial branding might add 2-3 days depending on complexity.
Yes, every batch comes with a full CoA showing purity >99.5% and HPLC results. We can also share third-party testing reports if you need extra verification.
We offer it in pre-measured vials (2mg, 5mg, 10mg) only—no loose powder. This keeps the stability and dosing consistent for research use.
Keep them in a cool, dry place away from light at room temperature. Once reconstituted, they need to be refrigerated at 2°C-8°C and used within the recommended timeframe.
