A good solid base... does NOT come from gear.
You build a solid base of solid muscle tissue by busting your ass for as long as you can, building as much natural muscle mass as possible.
Yes, believe it or not, there is such a thing as natural muscle mass. You have to work for it.
Once you've been at it for a while, you can then start thinking about adding some fake muscle to your natural muscle, taking the chance of course that you might lose all of that solid mass that you built through hard work, committment and sweat, just because you couldn't handle the shutdown that ensues after stopping the shit.
Muscle tissue has been tested in biopsies over and over. Muscle mass gained naturally has a harder, tougher and more durable consistency and is more likely to stay once it has been built.
Steroid induced muscle,on the other hand, has more of a watery, squishy and less solid feel to it. So much water is retained inside the tissue. Upon cessation of juice, this shit just disappears.
If you think after a strong cycle that you made some solid gains, it's not steroid gains, it is the fact that the juice made you work harder, gave you more energy and helped you add something to your natural base.
If this sounds contradictory to you, you are not understanding correctly and I am not explaining correctly.
Solid base = natural muscle.
The thing you tell a teenager to do.
