I don't necessarily agree with bashing you, but I definitely understand why guys do it. Tough love man, they are just looking out for you. It's easy to get pissed off when you see so many young guys on AAS boards screwing their bodies up (potentially for your entire life) by using gear WAY too young. I speak from experience, did my 1st cycle at 21 and even that was too young. Terrible decision, but I was young and dumb like you.
If you want to know why it was a dumbass decision (more than just the usual you have so much natural test, gains are easily attainble, etc stuff), I'll PM you my email since you can't PM yet and we can talk more. No bashing, just straight real talk from someone who's been in your shoes. Let me know if you want me to shoot you a PM, I'm not gonna waste my time if you don't wanna hear what I have to say. Take care and stay safe.
