How To Use

Fill a 22-24 oz bike water bottle or container with 16 oz of room temperature water. Add 2-3 scoops of Glyco-Durance RAW™, 1 scoop at a time and shake 10 seconds after each scoop to avoid clumping.  Adjust for flavour preference using Unflavoured Glyco-Durance RAW™ (i.e. mix 1-2 scoops of Unflavoured with 2 scoops of flavoured Glyco-Durance™, ) When product is blended add the remaining 6-8 oz of water.  Let sit for 10-15 minutes and shake again for 30 seconds before drinking or dispensing into 22-24 oz bike water bottles.  You can also blend up Glyco-Durance™ in a blender.

Mixing a Glyco-Durance™ and Glyco-Durance RAW™, Super Bottle (in a blender)

Add 8-10 scoops* (100 calories per scoop) of Glyco-Durance™ into 20-24 oz of room temperature or slightly warm water and blend for 30 seconds.  Transfer into bike bottle and drink over 2-3 hrs.  We recommend a ratio of 6-8 scoops of unflavoured Glyco-Durance RAW™ with 1-2 scoops of flavoured Glyco-Durance™ or flavoured to taste preference and electrolyte ratio needs.  This will give you a concentrated bottle with 800-1000 calories.  Remember to drink additional sips of water when using an F2C Glyco-Durance™ and Glyco-Durance RAW™  Super Bottle.

Glyco-Durance™ and Glyco-Durance RAW™ can be prepared and frozen in your bottle for your convenience.
