We've been supplying labs working with nootropics and neuropeptide research for years now, and the SemaxSelank combination is one we see most often for studies on cognitive function or stress response modulation—usually from buyers who want reliable baseline without sourcing multiple individual peptides.
Purity runs at 99% or better verified by HPLC and MS, which is tighter than what some smaller resellers offer, and the is water soluble so reconstitution is straightforward with sterile water or saline. Storage is the main constraint—2-8°C, protected from light, and you'll get the full 24-month stability window if you keep it there. We usually have stock for the SemaxSelank (CAS 80714-61-0), but NAD+ and Epitalon variants we carry might have different lead times depending on batch demand.
What you get when ordering is a customizable packaging format—vials or bottles, depending on your volume needs, and we'll include the COA with each shipment. Most buyers go with the 10mg vial size for initial work, but our company can do larger quantities if you're scaling up. Basically, if you need a specific gram count or labeling, just note it when you place the order.
One thing that catches people off guard is that this peptide complex isn't suited for any in vivo human work—it's strictly research use only, and we don't provide dosing guidelines or appliction protocols. So make sure your lab's compliance paperwork is in order before you order.
The molecular weights vary by product (roughly 900-1100 g/mol range depending on the exact batch), but that info is on the COA if you need it for your calculations. Also, teh lyophilized cake can look a bit denser than you'd expect from some other peptides we've handled—just a handling note from experience.
We ship in insulated containers with ice packs during warmer months, and the MOQ is typically 1 gram or 10 vials, but confirm lead time if you're ordering less than 5 grams—we can usually accomodate, just not always from ready stock.
