I am a 60 yo using creatine to maintain muscle mass and for health span benefits. I work out about three times per week and have noticed a small improvement in the number of reps I can do. Other benefits are longer term and difficult to quantify.
Cocrystal has massively helped my recovery. Noticed it dropped off a lot since pulling PED's down significantly, taking ages to recover but my days this is the business!
One capsule after training helps me to relax as part of the cooldown. Two before bed reduces initial insomnia. A helpful addition to my supplement regime.
