While i certianly wont say its 'better' then ARA as ARA is a great ingredient, i truely believe Alphamax could be a compareable option in terms of increase size and recomping effect.
Alphamax contains a clinically proven dose of Forskolin 95, shown to increase Lean Body Mass while decreasing Fat Mass. It also contains a very potent AI called Arimistane that lowers estrogen and boost natural testosterone production, creating a leaner harder physique. As well it contains Divanill and L-DOPA, proven to increase Free and Total testosterone.
Alphamax would be a great option for a natural anabolic product, its actually #8 on the top 100 list on Nutraplanet!
