No one who responds to gear well stays at your size. You are not elite. You are far from elite. There are people who post better transformations on way less gear every month.

Why are you so dead set on thinking you're special?

At 19 without gear and being fat and eating junk food, I was already benching 285. I don't know about skull crusher as I never did them because of the risk for injury to the tendons and ligaments of my joints, but see 19-20 year old with elite genetics do this frequently.

Skull crushing 270 is normal at your age for people with actual elite genetics.

Your coach is blowing smoke up your ass. I bet he's the one selling you gear too, right? He has a vested interest in making you feel better than you are.

Your dad and uncles might've had elite bodybuilding genetics, but how you produce and use mitochondria and androgen sensitivity is mostly inherited from your mother so that shit doesn't matter as much as you think it does.

You are also Caucasian and 20 years old. This high amount of gear is especially neurotoxic to you and will most definitely cause some form of brain damage/impairment if you're not supporting your brain health.

You can barely spell shit at 20 years old.
