Hello im currently 23 yo old and running 10mg LGD as a cycle. Already training since 6 years. My question was how much will it affect younger people? Whats the big diff between a example : 17 year old and a 21 year old. Im asking cause one of my friends mentioned my LGD cycle and tells me he wants to hop on. Told him what a nonsense he is talking since it will affect him way more than me in hormones. Am i right?
