Lookin to specifically add hardness for looks. Have tried both mast and halo with both very similar dissappointing results. Think the mast i took was too low by dosage and the halo was poor quality. Having said that if i was to take just one of those specifically to add hardness and detail which is the more preferable? By the way if i do either would run my mast at 800mg's per week and have a real high quality halo. Thanks for the input and feedback.
