I"m gonna say NO first. I really don't recommend that anyone get invovled w/ that stuff unless they are pursuing competition. And again, both are controlled substances and SUPPLEMENTS. THey shouldn't be even considered unless there is already a solid, consistent and well-established diet , training & cardio regimen.
Can you give us some background as to your fiancee's current stats, (weight , bf), specific goals, current training, diet & cardio regimen, how long on those programs and results to date?
