This cycle is definitely the GOAT. I would run all three together. Make sure you go for 12 weeks and make sure you cut the winstrol to just eight weeks.
I would start out even at one or two IU's per day. See how you like that. Then you can transition and start using three to four IU's and then go from there.
Primo is the GOAT but it's hard to source these days. If you can find it, do 400mg a week and do anavar with it at 50mg a day. That's a really good stack.
