I tried this out on my long run last Saturday. Chose this over Hammer Gel at the time since there was no more supply of Tropical flavored Hammer Gel (my fav) and this one costs P5.00 less. Bought 2 packets. Had 1 before I started the 26km trek and another midway.
Verdict? There really was no effect except for the "bleck! too sweet!!!" taste. No "kick" nor sting like how the HammerGel provides.
Sorry, I'm not buying this anymore.
