lmfao. You think this is how you're keeping your nephew safe?!
You need to do more research YOURSELF. Not come to some board you dont know shit about and ask complete strangers how your 16 year old nephew should inject himself!
Wtf is the matter with you!! I understand your concern for your nephew completely but i speak from PERSONAL EXPERIENCE. I juiced too young and know the cons that come with it FAR outweight the pros.
As a responsible adult and caring family member, I would expect you to do the research yourself and prove to him WHY its so bad for him. Thats like teaching your nephew how to inject heroin...so that hes safe when he does it...
Come on man....
