I noticed a pleasant tingling sensation and mild muscle contractions, which reassured me it was functioning properly.
Over a few weeks, combined with my regular workouts and healthy diet, I felt my core muscles becoming more toned and firm. It’s important to remember that it’s a supplement to exercise, not a replacement.
