it depends on ur 85 kg of weight if mostly muscle or fat.. if ur mostly fat or just a normal built guy.. by taking mass gainer.. rather than being big like rugby players... ur gonna be big like rikishi... no offence.. but looking at ur height and weight.. you are obese(if ur fat % is over 25%)

if i were you... i would drop my weight till about 70kg(which is what im doing now) then start building my body from there..

i used to be 110kg.. currently 76kg.. aiming for a body almost like the one you posted.. but not that big..

i dont know about you... but dont you think its a bit ridiculous for you to think that you dont wanna drop ur weight but u just wanna gain muscle??

you have to do a combination of loosing fats.. and gaining muscle at the same time.. and loosing fats are fast.. gaining muscle mass are slow...

so... for you to think that u want your weight to be constant.. but loose fat and gain muscle??????

really headache.. go read stickies..

and for you to be that big.. doesnt neccessarily you have to be that weight..

its what in the mirror.. not the scale...

look at darklight.. bigass bis tri ches everything... but is lighter than me..

puhlezzz read stickies or at least google it before posting k brah...
