Monster Mix for a teen?

So for an early Christmas gift my girlfriend got me this new sup called monster mix, some russian mass gain test boosting sup, and honestly its pretty good, good gains after bout a week, but i caught my little cousin sneaking some(he lives with me that's how he got it). Says he's been doin it for a 4 days, he's 17, 6'4"ish kinda fat, but pretty strong. My question to you all is do you guys think it's safe for him? My biggest fear is that it will mess up his hormone track, and his body will get physically dependent on this **** to make testosterone, like most test boosters do to teens. But their website claims (well used to, it changed a bit) that it won't mess anything hormone wise. Thanks

Looks like a pretty shtty product.
