I have tried both...it's no comparison; if you have low body % fat; diet and training up to par...Primo is light years ahead of Anavar. It's virtually side effect free, w/exception to shutting your HPTA axis which can be somewhat sustained w/ZMA and Tribulus. In addition; it's quite easy to recover; takes approx 2-3 weeks w/no PCT necessary. Primo will rip you up, and build nice lean muscle, you just need to stick with it and run it for at least 10 weeks at 250mgs minimum per week. If diet on point you will realize this is a body changing drug...Another plus, may not be tremendous gains but whatever gains are made, 80-90% are retained. No other gear can match Primo - safety/effectiveness - 10's all around. Anavar on the other hand may produce nice effects but you're compromising your health as liver tumor cells are inhibited. Is that worth it? It's quite liver toxic, and you do build up a tolerance since it's oral hence you will need to take more to realize the same effect which adds to the harm. You cannot put a price on health. Final notes: Cycle properly and do research - ensure dealers/labs are reputable. Primoforlife
