IFMC knee support, size M. Instant purchase ○ Thigh circumference: 25cm-40cm. IFMC, impregnated in the support, increases nitric oxide production from the vascular endothelial cells, which dilates blood vessels and promotes blood flow. It can be expected to aid in fatigue recovery and alleviate muscle fatigue and stiffness. I also use it and highly recommend it! #IFMCcream #Doctorsupport #IFMCsupport
