Need a backup lab supplier for small peptide orders
I buy research peptides for a small lab bench, not a store. Usual order is Semax and Selank in a few vials, sometimes a repeat the same month. I usually order that bulk because the batches come with paperwork and the box is just vials. I still want a second source in case a lot is late.
Do you split small peptide orders across two suppliers, or is that more trouble than it is worth? And what do you check on a COA before you accept the shipment? I am not looking for a retail brand. Just a steady wholesale line.
