Most researchers I've dealt with mix Semax and Selank for stress studies, though DSIP is usually run solo for sleep cycle work — that's just what we see form labs ordering repeatedly over past few years.
We've got the 2mg, 5mg, and 10mg vials on Semax and DSIP (Selank skips the 2mg because demand there is lower), and teh MOQ is pretty straightforward: one box of ten vials per peptide, no need to commit to huge volumes upfront.
Purity runs at 99% or better on all three, which we verify via HPLC on each batch — the COA is included with every order, so you don't have to chase us for it after shipment goes out.

Storage is key here, since these are lyophilized powders — you'll want them refrigerated (2-8°C is fine), and they hold for 24 months or so that way, but freeze-thaw cycles will degrade them faster than most buyers realize.
Actually, one thing we don't push these for is any kind of human appliction — these are strictly for lab research, and we're upfront about that because we've seen the regulatory headache when someone tries to use them otherwise.
Lead time is typically 7-10 business days after payment clears, but confirm availability because some strengths like the 10mg Selank can run short during peak order periods.
Our MOQ is 1 box (10 vials) per peptide. You can mix vials of different dosages within the same product line to hit that minimum.
Standard lead time is 5–7 business days after order confirmation. For larger custom runs, we'll give you a specific timeline at quote stage.
Yes, we include a CoA with every batch. It shows HPLC analysis confirming ≥99% purity, so you can verify the specs yourself.
Keep them refrigerated at 2–8°C in a dry, dark place. Once reconstituted, use immediately and don't store the solution for later.
Absolutely. We can adjust the mg per vial within the available range (e.g., 2, 5, or 10 mg) and add your lab's label. Just tell us your specs.
