Damnit 308power, get out of my head! Totally what I was going to type.
OP: I think pictures will speak louder than words here:
Torn pectoralis minor.
Torn labrum (post op)
Distal biceps tear.
These are all examples of what can happen if your body does not have the time to grow it's connective tissues properly and is forced due to accelerated muscle growth to perform harder than it can. This is just
one example of why young folks shouldn't be taking AAS, especially ones that haven't put in the time (like you) into the gym to build up those connective tissues. Let puberty do its thing man, don't rush into a lifestyle that can cause serious PERMANENT damage because you're impatient.
I don't even want to delve into the HPTA issues you could potentially suffer.
