Hi guys...i've been new here...

Just seek for an advice. Currently, i weight around 85kg >.<" before this i was around 105kg (roughly). Im about 172 cm height. So, im looking for a supplement for a bodybuilding. Anyone can recommend any good protein for muscle build? I have a big body right now but those lean muscles arent much visible unless just finish gym session. So, i want to try some supplement and preferable, some guidance during gym session

No pain no gain.

yea....before this, i was using GNC 100% whey protein. Then, some friends recommend me nitrotech. So, whats the different? Isnt it just only a brand??

Somehow, the brand doesn't matter (i guess). Just looking for what type that able to hasten the process of muscle growth.

Cytogenix Xenadrine RFA-X

anyone heard of this?? How this work?? is there any side effect of it?

recently, i was recommended with this product. So, b4 purchasing it, i hope to get an idea whats that product and how useful is it

thanks...
