I got about 80 amps from RB u don't need to worry there, easy way to tell the oil in the vials will be super super thick it'll get stuck in the neck of the vials and u'll have to flick it , also the oil will be super clear... Another give away is when u snap an amp sometimes it'll almost have a sugar smell to it.... Also iv got them with the boxes before flatend so they could fit everything and I was able to check them on the it's app... Iv shopped strictly with rb for all my pharma grade needs hgh everything u deff got legit primo the oil will be super thick and take awhile to draw and I can tell from what I can see in the pic of the amps they look 100 percent H rb is soild as they come, he's my main src and there is only two others I would trust but ur in the best hands with rb
