This is gradual, cumulative support, not a fast-acting drug — here's a more honest, week-by-week timeline instead of an overnight-results expectation.
Weeks 1-2 bring little to no noticeable change for most people. Weeks 3-6 are where most reported change happens, particularly for stamina and endurance. Weeks 7-8 are a fair decision point, falling right inside a typical 60-day guarantee window.
Assessing a gradual-support product at two weeks is assessing it too early — the guarantee window is deliberately the same length as a fair trial period, worth using the whole window before deciding.
60-day money-back guarantee, per the manufacturer.
