yes, as you do not have the same formula, the insulin spike you can get with yours is much less. you can probably sip on it during your workout and be fine. although you should try a couple of different consumption patterns. after a few workouts with each, you will know which one is the best for you.
this is what works for me to avoid the crash:
for longer workouts, i have had to make two drinks, the first is 31g or Surge mix (1/3 serving) with half a scoop of whey and 7.5g of BCAA (i use xtend for workout mixes, Biotest BCAA pills for during the day). i start drinking this before my warm up and finish it halfway through the workout.
the second drink is like the first, but with twice the Surge (62g) and half a serving of greens+.
post workout i sip another shake like the second one, but with a full serving of greens+, 5g of creatine and eat a banana. i am eating a real meal within an hour of finishing the workout.
Surge: 5/3 servings
whey: 1.5 scoops
greens+: 1.5 servings
banana: 1 (about 25g of carbs)
