For best results take 4 capsules 2 hours before training. This is due to the research suggesting that using nitrates in this period will improve exercise performance (Ref). However, if this is not feasible you can take any time of the day. This product has no stimulants, so it is safe to take in the afternoon or evening.

The key is to be consistent each day to increase overall saturation in the body, so try to build it into a routine that works for you.

If you are using leading into a competition like a marathon or fitness event then work back and start supplementation 4 weeks prior. This is the minimum time frame we suggest to reap the benefits. You can then add extra months on to help augment better training adaptations.

Peak Endurance can be taken with food or on an empty stomach. It can be taken with water, a hydration product or a sports drink it doesn’t matter.
