I'm trying to get "caught up" on the newest and best supplements after being out of the hobby/lifestyle for some years. Rep-cal pink lable used to be the way to go but it looks like Rapashy is the hot set up now. I cannot find it locally so I'm forced to order it online. It looks like they have several different formulas.
My question to you is which Rapashy supplement should I order.
Any help in this matter will be greatly appreciated.
Thanks in advance!, Mike
