10kg? No way. It would be mostly fat and wouldnt benefit him in any way.
The most amount of pure muscle its possible to put on in 1 year with proper consistant training and diet and not using steroids, is 3kg.
Explain to me the science behind that, or even tell me where you've heard it from?
Regarding the 10kg, yeh 10kg would be way too ambitious in one summer (I've already corrected myself on that). 5kg of lean muscle in a summer is definitely not impossible with the correct training and nutritional protocol though. It would take extreme dedication, but in no way is it impossible.
