It really comes down to your budget, how interested you are, and how you see the whole situation. I almost never want to cover delivery when ordering at standard prices and need to meet a minimum for free shipping anyway.
I'm preparing to place my first order for this type of peptide. Is it smarter to start with one kit and cover delivery just to evaluate everything, or buy several at once since delivery can equal half the price of a single kit? Three kits seems reasonable because my husband and son will probably want to try it as well. I've settled on the 10 mg vials so I can begin at a low dose and increase gradually.
