    Disappointed and Still Waiting Results

    Used it consistently for a month. No noticeable changes in performance or recovery. Just experienced mild headaches. Totally underwhelmed by the hype.

    No Muscle Gain After Weeks..!!

    I followed the instructions daily, but saw no improvement in strength or size. Felt like a waste of money. Wouldn’t recommend it to serious lifters.
