im guessing you are going to run the 4-diol @ 1,000mgs +,
so I would say for all out mass, strength, go with sd/pp/hd.
4-ad for your test, you can run just about anything with it, just depends on your goals.
but 1g 4-diol + 20mg sd/pp/hd should be lovely, and strength unreal.
I've ran it before, and felt like I never wanted to leave the gym, and was swole all day. people notice.
hd may not be needed, but I certainly loved it.
