I'm 43 years old, been lifting for over 20 years. In those years there is a mixture of bodybuilding, then leaning out to get back into Motocross and then a 5 year run with MMA training. Anyway now that I'm 43 my testosterone is low, as a matter of fact as of 2 years ago it was measured at 380. My doc tells me that this is normal (kinda what I expected from a doctor), and I disagreed and when I asked for injections,( I won't take steroids unless prescribed)of course she refused. So then my quest for testosterone began. I have taken USP labs which has decent products, but I didn't get the pop I needed. I then tried various testosterone boosters from other companies...still not feeling it. Now nearly 2 years later I decided to give Sustain Alpha a try. I bought the cream and it didn't work nearly as good as their liquid form, and the reason for that is simple, I sweat a lot (Contractor)and it washes off. That product is better suited for anyone in a climate controlled environment. I did feel something on days I didn't sweat, so I was a bit convinced. Since switching over to the liquid form my life has changed!! I feel the boost and that aggression to hit the weights again, I haven't felt that in years!! The sperm volume is back! my outgoing nature is back...wow you really don't know how Test is missed until its gone and we tend to take life as this is the way it is....Eff that. I got bigger and I anti aged a bit. TOCO 8 has restored a good 30% of my hair. It made what I have much thicker, but the hairs lost for more than 10 years will never come back and that's just a fact. But between the hair volume increase and the much needed testosterone I feel effin amazing. I just hope PP doesn't ever change what their making, this was a life saver.
