Has anyone here ever had shortness of breath on cycle especially with anavar or winstrol? If so, how long will it take to go away after stopping the use of AAS. What im taking is suppose to be var but I think its winny and I might of taken a little too much. Could I be having an allergic reaction? My chest is tight, throat is a little tight, shortness of breath, blood pressure is fine. Its been 36 hours since my last dose.
