I'm not so sure
As a result of Huddersfield having the Galpharm stadium I made the informed purchase of three tubes of generic acyclovir for £4 off Ebay as I could see that in the picture they were produced by Galpharm
I saved around £ 14 on the equivalent cost of Zovirax!
If advertising doesn't work I'll eat my Swinton Lions davey crockett hat circa 1986!
If it's made of BEAVER you may need a proprietary treatment which is a little stronger!
