Just a quick little hit about Coedygen5 that a buddy was kind enough to give me. I only needed 2 caps to get impressive effects, and the recommended dosing is 3. There was actually an extra pill in the bottle, so I even tried 1, and got results, though not as good as 2. I always start on the low side of anyting. This stuff easily does what the label says it will do. Cardio was way easier, and I recovered quicker between sets. Tried it at night before bed as well, got a sound nights sleep. In my opinion, it would stack very well with other supps. This is speaking from someone who has asthma. MST did a great job on this product. Just sharing an honest quick review based on a six days of use, and not dosing every day.
