I am getting nothing but mixed reviews on the difference of the the toxicity if taken orally or injected. Some say there is no difference so why inject? Some say it dissolves easier in water although, it can be dissolved in oil with a talented chemist. They say the half life can be the only difference where injectable stays longer in system. If injecting oil based winny just absorbed slower. I have only using for about a week now and had minimal pip except if I sleep on my shoulder where I usually inject winny. I guess I am more curious then anything and can't help to wonder what they use to help dissolve the winstrol in oil. Good day mates!
