BETA-7 or Poliquin's Beta Alanine?

Hi

Just wanted to see if there are any here who have tried one or the other(preferably both) and hear some reviews.

Partial Bio-I’m a Judo player,training in Japan and I compete about twice a year against guys about 10-15 years younger than me.I put in the necessary work as far as GPP & SPP (Run Stairs,Sandbag lifting,Sprints,bodyweight circuits, barbell complexes,ginastica natural,etc.)

But I am looking for a legal performance enhancer to prepare for my next comp in May.Beta-Alanine looks good but I can’t decide between Biotest and their time release product BETA-7 or Poliquin’s Beta Alanine Supreme with Creatine.

Looking forward to some feedback.
