UPDATE: Day 15... we're totally retarded. No, seriously... I need to admit this: We've been TAKING THE WRONG DOSE. Way back on Day #3, we changed syringes to a smaller one that fits easily in the bottles and didn't realize that we had gone from a syringe that was graduated in mg's to one that was a % of ml. So, when I thought I was taking 20mg, I was actually taking .20/ml which is only 10mg. (50mg = 1ml) All the gains in strength, vascularity and shred have been on a *tiny* dose for the last 14 days. Last night at the gym I was putting up 10 more pounds on every machine for more reps. I tore through a second set of bicep curls at 10 reps/side with a weight I can normally do 6. I even did the last 2 in slow motion to get a full pump. I know my body very well as an endurance athlete - this is NOT a placebo effect.
We've fixed our mistake, and started today on 50mg (1ml) of S4 each. Woah, this should be interesting!
