True but they effect everyone diffrently, someone really close to me uses them.and Yes they can go eather way. I've used them, dont anymore, thats why I've resuched them...and I dont recomend anyone trying them...diffrent roids effect you diffrently, they helped me a lot, because I have a extremly hard time gaining weight, but unless you have done them and have been educated on them, you dont now what they can do to you mentaly and physicaly. If you are a teen it is a very, very, bad idea to use them. The side effect that causes the most problem is rage, for anyone reading this i cannot stress this enuf..they will mess with your head and make you extremly tuchy,like you said you need to be educated on them,and at least 20 years old to use them. I can tell you this it is very easy to abuse them, and they can cause dammage to your body. I really didnt want to tell anyone that I've use but, in all reality they are not safe if abused, and most people I no that use them also abuse them its very easy to do. let me ask you a question have you use them do you no what it feels like on them? do you no how they change you mentaly when you are on them? I'm not trying to argue but I know first hand what they can do to you, and if you think its safe doing a roid stack or staying on them for long periods of time with no side effects,or even doing them moderly, well sry bro you had better think again.yes It feels great on them I loved it,I fealt better than i had ever fealt in my life,and yes they helped me, but everyone around you might think diffrently.....Almost cause me my family and freinds.anyways sry to see you go Eddy my hart goes out to your fammly R.I.P BRO...
