No change is an answer. What matters is what you do before the guarantee ends.
Compare your log's weekly averages with the baseline. Consider whether other things changed: sleep, season, stress, training. The brand suggests 90 to 180 days for results, so you may feel you have not given it a full chance.
The guarantee is 60 days, and our gap guide explains the tension.
Request a refund in writing before the deadline if you do not want to continue. Continue past day 60 only knowingly, understanding the refund option will have ended. If tiredness or low mood persists regardless, see a doctor, since a supplement is not the right tool for an unexplained problem.
