I think it's going to have more to do with you and your reaction to prop then what brand ... I can take LSP as well as a host of other test prop in the glute with no problem at all , now the quad is a whole other story .
Prop is the olny thing i can't site inject ... no matter who's brand , the glute is fine but thats it .
My man is switching all his injectables to EO from BA or BB , so i asked if he'd set me aside a vial to try site injecting with .... hopefully it's just the BA , I'll find out in a few weeks .
Right now i'm on prop from API and Universal labs as well as VIRORMONE by Nordic and all have injection issues ...
