A great source of quick carbs. I only use Karbolyn during my workout for intra workout nutrition. But i am sure it works well at other times of the day. Mix with some branch chained amino acids and a little Citrulline malate for an awesome intra workout stack. I only use half a serving so it last me a good amount of time. The fruit punch flavor mixes well with other flavored BCAAs. The price is not bad especially when you only use half a serving every workout. Well worth it.
Overall, Karbolyn is a very good product. It is obviously filled with a lot of carbs, so it is best used in a recovery time when in a bulking phase. I don't necessarily think this is an essential supplement, but it definitely helps if you need some good carbs. It's a good price, so I would definitely suggest it.
This is the first carb drink that I was introduced to. I took 50g of carbs pre-workout and 50g post workout. I felt more energized during my workout. Not a pre-workout type of energy but more of a not getting worn out so fast type of energy due to the fast digesting carbs from this drink. Taking it immediately after the workout, I could definitely tell the difference later in the day and the days after. Muscles stayed full and I my recovery was much better.
