do you mean taking them together as part of a supplement regiment? or like at the same time?
taking them combined is fine, they all ahve different purposes.
imo your fine.
just a word of advice...i dont think HMB is worth it. HMB has been shown after repetitive use and more advanced bodybuilders dont see effects. If you are just starting out use it, but after a few months its really not worth it.
