You down voted him?!?! Jebus..... This is about as good and REAL as advice for your circumstances can get. If THAT makes you feel like quitting....then just quit now and save yourself the time.
WHY will it take a while to see gains? NO, he wasn't just trolling you, it WILL take TIME. You aren't trained and adapted to this stuff. You MAY see dramatic gains, but you may actually go in the reverse FIRST because suddenly putting your body through proper lifting and plyo regiments for these kinds of pursuits is gonna SHOCK your system and getting out of bed just in the MORNING is likely gonna be rough, let alone seeing "massive gains" immediately. If that's gonna make you quit, then you'll never come out the other side to see ANY gains, let alone massive ones.
Theoretically if you're a so called big "responder", you may see some massive gains early or right off the bat. But that's unlikely based on the info you have provided across all of the internets. If you want it, by all means go for it and get it, but if you're just chasing some weird "status", then your setting yourself up for failure on a variety of levels.
