Check your shoes too. The wrong shoes/insoles can cause incorrect foot movement during your step, such as pronation, which usually cause shin splints. This is probably be accelerated by the tren so you're feeling it sooner. Perhaps look into those foot skins or even barefoot running/walking.
he doesn't have shin splints but good advice.
trust me I know what shin splints are and let me tell anyone who has them don't listen to anyone except your own body. if they get too bad then JUST STOP. dont run through them cause you will only make the problem worse. the only cure is rest and I mean 3-5 months of rest.
