Old PHs vs SARMs Questions

I’ve been out for a while and got back in the iron game a few months ago. I used to use SuperDrive, halodrol and epistane and built a decent physique. In trying to order them it appears they “changed” all the formulas and are trying to cash in on people not knowing the difference? Should I keep searching for the old formulas or are they gone? I really enjoyed them as I knew what to expect. A friend told me if I can’t pin to look into SARMs. What would you guys recommend? Thanks!
