well, there are the normal dht sides. If you are predisposed to male pattern baldness, this may accelerate the process. I also noticed alot of acne on my back, but I have always struggled with this so I may have gotten it worse than others. Other than the two that I mnentioned I didnt see any other side effects. There are some other possible sides, but these are the most common and the ones you will most likely see.
It is great for strength and hardness, it makes you very aggressive also and is a quick acting prohormone. Most people can "feel it" per se withing 2-3 days. I would suggest if you took 3alpha orally the dose be 200-250mg a day, if you go transdermally I would say 100mg a day (this is if you are stacking). You can also go with 3-beta (cheaper) at 4 times the amount for 3 alpha.
Hope this helps
