An embarrassing amount for the quality and size of physique I have. I will say this though, for you newbies out there: don't believe for a minute that you gain x amount of muscle every cycle and just keep adding and adding. It's not that simple. Also, sometimes a person has to find what works for them.
I guess if I had just done huge amounts and stayed on I'd be bigger. But, I experimented and piddled around often losing most of my gains and spent too much time focusing on competitions rather than building a good base. I'm kinda like that, just jump in feet first. I didn't do well in competitions and I didn't build a great base either. So, it works out that I learned the hard way and accumulate my gains a bit slower.
I did my first cycle sometime around 5 years ago and have done 2 or 3 per year since, mostly 6-8 weeks with equal time off in between. I'm getting my best results ever now doing moderately dosed cycles (up from my tiny doses I first used) of around 800 mg total per week for 6-8 weeks at a time and using sarms s4 in between cycles. I also just started using GH 3 times per week post workout- I like the sounds of that protocol as it reportedly doesn't shut down natural production so much and gives better overall results. Or, so I hear. My skin looks better at a few weeks in, I can tell you that much. We'll see in 6 months how the gains/fat loss works out. viva la experimentation!
