There is no Alternatives. You either spend money for the real stuff or lose money on the Alternatives another words fake stuff. There are some things that help but nothing will ever compare. Only thing I will say is stick with all in one compounds like NO-EXPLODE, or ADENERGY STACK by optimum nutrition. these things contain things like creatine-Dicreatine malate, L-Glutamine,Arginine,L-Taurne,L-Alanine,L-citrulline Malate, ADTP5. These things along with eating every 2-3 hours good solid proteins and training heavy and hard 4-5 days a week will deliver decent results. But there is no beating cycling a good Test and Deca cycle or maybe even EQ and Test something small and sticking to a reasonable dosage and reasonable cycle time. It's not advise bro it's just opinion
