bro, the first guy I heard about EO eating away the stopper was from Georgie24. Before him, I read an article about AAS users injecting rubber from the vials thus causing cancer because of the rubber particles. I think that article was concluded to be complete bullshit. and Ive never read any scientific material saying EO rots away the rubber.
Also, another thing I thought of as I was just now coming home from the gym. If you keep all of your vials upright, the EO/oil will never touch the stopper right??? That would mean theres no way it would happen then. I think its bullshit.
Oh and yesterday was my first stick with the EO prop/ace/mast combo, and just a little soreness from the actual inject, no pain from the gear. I was nervous and jabbing in and out while injecting and it is still just minimally sore. just feels like a light bruise. I was all worried and shit that the prop was going to cripple me like winny does. I honestly think the crystallization of winny just effects me worse than most others.
