In 2015, I was injured playing in the NFL. Since the injury, I experienced random knee pains, especially during the winter months. Since using SERUM X, my knee pains are few and far between. SERUM X has been my go-to pain relief product because the pain goes away so quickly. Looking back at all the injuries I experienced and had to play through during my football career, SERUM X would have been the solution instead of pills that can be damaging to my kidneys and liver. Since using SERUM X, I haven’t had to use anything else.
