Most labs we work with want to tweak vial sizes or label designs before they commit to a bulk order—custom concentration is pretty common too, we can do 50IU or 100IU per vial depending on your batch. 2. This peptide runs about 4.1kDa molecular weight, HPLC-verified at 99% or better, and it's a white freeze-dried powder that dissolves easily in sterile water; we filter-sterilize every vial so endotoxins stay under 0.1 EU/mg. 3. Storage is key here—keep it at -20°C and away form light, and you'll get roughly 36 months shelf life, but if it thaws during shiping (which happens sometimes), it's fine as long as you re-freeze it quickly. 4. Actually, vacuum-sealed packging with desiccant helps a lot for stability, but it's not meant for anything beyond research use—don't even think about human consumption. 5. MOQ is 10, and our company can do custom bulk synthesis if you need bigger runs or different concentrations, though lead time for that is usually 20 days or so. 6. For orders, we ship from US stock in most cases, but confirm lead time for custom stuff since it can vary.
