Can a 5"5 16 year old take maximuscle safely and effectively?

I am 16, short for my age and relatively thin, and desperately want to bulk up! I've been on the maximuscle site and read reviews and they say in order to bulk up muscle and size i should take a mixture of progain extreme, promax, maxi-EFA and cyclone. I am 5ft 5 and weigh just about 50kg . Will it be worth the price for me to try maximuscle? i know they're expensive. Thanks :)
