For the past week I've been doing early morning (5:30am'ish) workouts with a 10mg/ed D-bol bridge to help with catabolism. Strength has been good, and I haven't noticed any sides (no bloating) due to the minimal AM dosage.
However....my pumps have disappeared. During my evening workouts I could build up such a great pump that I thought my muscles were going to explode. During my AM workouts, nadda. I just finished 45mins of bi's and they feel just as un-pumped as when I got into the gym. I am doing strict isolation and I am not training with any less intensity than when I was working out in the evenings. I also know my D-bol's not bunk due to it being left over from my previous cycle. I take down some glutamine w/ creatine in a gatorade mix before the gym and right after. During excercise I sip on a diluted gatorade/water mix to keep glucose up due to my over-night carb fast.
I believe I am still stimulating muscle growth because of delayed on-set muscle soreness 24-72 hours after activity. But still no pumps! Not enough pure H20 during the workout maybe??
