I started with ammo I suck at eating breakfast so I started taking that. I now am taking Ammo and enduro and blaze. If I do eat breakfast I take a blaze before breakfast ammo around 930 another blaze before lunch and the enduro with or after lunch. I work construction and the Ammo helps get me to lunch without starving and the blaze and enduro give me energy to get through the day without a drop off and still have energy at home. I started doing winter bike racing last year and will see how they help this season.
