Just buy what you want/need and don’t think too much about it. Obviously your concern about order size is whether or not your order is large enough to gain attention from LEO, so I’ll just say that honestly they can bust someone for a single vial while overlooking someone else ordering 100g of raws. It’s just a risk you take OP. Every order is it’s own instance which can either be a bust or not. LEO genuinely will just nail your ass if they really want to no matter how much or how little you have. These questions come up from newbies all the time and I advise you google “Personal Use Steroid Bust” or similar search terms so you realize what you’re getting yourself into. Do not forget that while these drugs do not ruin lives or turn people into mass murderers, they are still technically illegal and you take the risk sadly every time you order. “But your honor, I just wanted to bench four plates” is sadly not a valid legal defense and if you are arrested you’ll be treated not much differently than someone with personal use quantities of Meth or Heroin.
