reset is amazingly effective. works every time i take it but it seems, for me anyways, it only really great when taken with or at least within a few hours of taking the stim. what i mean is, say you take reset ad for a month, stims will be very effective for that month that you are taking the reset, but once you stop the reset, tolerance will return return or partially return. again thats just me though might be different for someone else. i still love the product, i take it with my adderall when i really need it to be extra effective.
