Before you begin Carbolin 19 with your program, make sure you have everything set up and situated. That means your eating & lifting.
Many people complain that Carbolin 19 doesn't work and it's because of what I stated above.
I was on it for 4 months (4 caps daily) and I must say it did wonders for me. The only reason I don't take it anymore is the cost. It's 80 bucks a month if you're on the full dosage!
It did a tremendous job with lifting (my maxes increased 10-25 pounds more than normally) and it also made me feel mentally more powerful.
Have fun and good luck!
