If you start on 4mg weekly first time you’re probably going to make yourself sick . 500mcg first couple weeks to see how you respond !
My first time running it , I could only get up to 1mg weekly (.5 x 2 shots ) the side effects were to much for me as my body just struggled to adjust , shit sleep and constipated , and I have a high tolerance for most drugs be it pharmaceuticals or steroids . But yes everyone is different !
