I’ve been taking Serrapex daily for about a month now and have genuinely noticed less stiffness after my workouts. I used to wake up sore most mornings, but this has made a real difference even my physio commented! It feels like my joints are more flexible and recovery is quicker. Definitely a supplement I’ll reorder. 10/10 product 👍
