3 months to single digits is doable but that diet advice is horrible IMO. If you stuck with a moderate carb intake set with restrictions (no carbs after 4pm, etc.) I can almost guarantee better results than what you will be running.
For the glycobol try 1 cap with both low and high carb meals to assess your tolerance, the bioprine can wreak havoc on the digestive system for novice users using the compound often leading to an uncomfortable trip to the restroom until tolerance is made. Taken preworkout 2 hours before with some carbs will deliver amazing workouts without sacrificing
the ability to lose fat. You never want to eat right before a workout, 90 minutes before should give enough time for digestion of carbs and protein. This supplement works and I believe it will help you reach your goals. Good luck.
