I have ran a few cycles in the past two years. Never had any problems with pimples or acne. I ran a bottle of Decca 400 mg's a week for 8 weeks. I also took 50 mg winny tabs for the 8 weeks. I woke up one morning and my back and shoulders were covered with pimples. I have been putting some over the counter stuff on it but it doesn't seem to be working too well. It's pointless to be big for summer when you can't even take your shirt off. Any suggestions will be appreciated. Thanks
