Most guys I've known that sell ped's make shit money at it. Is he a chemist or something? The only way he could be making that kind of money from drugs, is if he's making them in batches and selling them to dealers.
He's not selling gear- he's selling cycle advice/design along with diet/training advice
If you can't connect the dots with the meteoric rise of social media the last 3 years and the sick amount of free traffic it can generate then you haven't been paying attention.
I don't know what his monthly PayPal statements look like but if 100k young, naive , wannabe body builders and juice heads think they can make a transformation like he did then they will sign up for guidance in droves.
Lets say he charges $300 for a gear/diet/training program and he has 20 new kids a week sign up.
That's $24,000 monthly, (-960 PayPal transaction fees) and that's still over 23k, just using the low-ball numbers I plugged in.
Remember two things.
1) He has a shit load of views and followers on social media
2) Young naive guys his age will do anything for big muscles
