I enjoy running (around 35k per week on average), but suffer from chronic pain from achilles tendinopathy and medial meniscus tears in my knee. The knee pain usually comes on in the middle of the night – trashing sleep! Cortisone injections and prescription painkillers have not worked. Have been using the Ultra BCP oil for two weeks now and have experienced great results with several nights of uninterrupted sleep, much less achilles pain in the mornings and a general improvement in post run recovery (ie less muscle soreness). 2 x 8 drops per day. Pretty happy!!!
