⭐⭐⭐⭐⭐

At first I wasn't sure if supplementing with the lactic acid buffer tablets had a meaningful effect so I paused for a couple of weeks. I immediately noticed my recovery was taking longer and wasn't as good so I picked up the supplements again and noticed an improvement. Seems these really do work.
