I take two with me anytime my bike ride is longer than 100k. Gives me the energy I need to keep pedaling. No negatives, it's a great product.
It absorbs very well,provides energy immediately and does not cause stomach ache.
These gel packs are easily consumed and the envelope is easy to access during my cycling. Felt noticeable energy within 3-4 minutes after consumption and hydration. Will buy again.
