I’d like to clarify the following details: Exact vial size – How many mg per vial? Vials per box – How many vials are included in one box? Purity – Your listing states 99.9% — can you provide a recent batch COA (HPLC & MS)? MOQ for test order – Can you supply 1g for initial validation? Shipping – Cost and delivery time to the U.S. (ZIP code [55044]), preferred carriers? Bulk pricing – What is your price per gram? Payment options – Which international payment methods do you accept? I’m looking to move quickly once I have these details. Please confirm.
