Getting quite worried about 7oh

I've been using 7oh products for about 3 months now and something just isn't right. I think it may have something to do with the solvents being used in these products. Tachycardia, adrenaline rush, chest pain etc. For instance, one morning before doing anything that would attribute to these symptoms occurring otherwise, I took 7oh powder around 30mg. I immediately experience bad chest pain and palpitations. Anyone have any info on how dangerous these solvents they are using can be. Ethyl Acetate, Hexane, Methanol, Acetone. Any info would be great.
Thanks
