Your right proportion/symmetry/condition can stand up to any amount of Mass.
I must have been naive to think that these pro bodybuilders were just on steroids,
GH,etc.
Heres another ex script from a pro bb.
He says,
I started using synthol about 3 years ago. I had been lifting since jr. high, but only seriously once I got into college. So I'd been lifting fairly, to very, seriously for about 7 years. Mostly getting ready for strongman comps.
After 7 years I decided I just wanted size -- no strongman anymore.
I had 20" arms but took 2 years off for work (intense job) and started lifting again about 6 months before synthol. So I had about 18" arms when I first tried it.
I am usually overanxious and began injecting pretty much everywhere. Starting with 1-3ml in each part: biceps, triceps, shoulders (all 3 heads), chest, forearms (just a couple times because they are stringy and you'll get one forearm muscle but not another, etc...and because I work at a computer all day and it hurt to type), traps. I tried lats, but gave up because I couldn't reach and I'd end up injecting into skin/fat. Tried stomach ONE time because it's freaken scary (how deep do you go??) and bruised like mad. Tried calves, quads and even hams. But quit on those -- requires too much liquid, and hams are too stringy w/o a major "head" -- kinda like forearms.
I would do like 10-20 injections/day (suxed really bad). It was so many because I'd inject nearly everything every day (1bicep/1tricep/3delts/1-3chest/1traps then the experimenting w/ legs and forearms).
Eventually I got to the point where I could hardly breathe and would cough all the time. This is BAD. If you get to this point, you're using too much synthol, and as you'll learn as I add to this, using more does not mean more size.
