I’ve got some antihydral for sale, £13 per tube with free first class postage.
Stick it on your fingertips if you’re beasting it and they’re getting thin. As far as I know, it seems to toughen up your skin by reducing the amount your fingertips sweat. There’s a thread on it here

http://eveningsends.com/2011/07/review-antihydral/One tube lasts ages, as it should be used sparingly.
If you climb at evolution in Tunbridge Wells or are out on the sandstone, I can bring one down to you there and I’ll knock postage off.
Any questions, just PM me.
