Aight bro I got some imput for this. Im also 19, turned 19 in Oct, I also bulked a bit, gaining about 30 pounds from then to now, currently 6'2 225 pounds. Im experiencing fairly significant stretch marks across my chest and biceps...and im still around 12%BF so seeing how your lean now, if you bulk youll inherit stretch marks...I dont care about them just part of the game, but you might. Make sure as you bulk buy some Vitamin E oil and cover your arms, arm pits, chest to help with it |
