Shaun Ryder would "drop dead" without testosterone injections.
Despite looking forward to the "energy" boost he gets from his quarterly injections, the Happy Mondays frontman has revealed he would be dead if he didn't get the injection every three months which he needs because he has no thyroid gland.
He told NME: "I get a testosterone injection once every three months and it makes me feel like I'm 21 again. I'm serious!
"I've got no thyroid. I have to take 150 micrograms of a thyroid replacement drug daily and the testosterone injections or I'll drop dead."
Shaun revealed the news ahead of the Black Grape reunion, a fundraising gig at Granada Studios in their hometown, Manchester on Saturday April 11.
The band will also celebrate the 20th anniversary of their debut album 'It's Great When You're Straight... Yeah', without
dancer Bez who has decided not to share the stage with his former bandmates in order to concentrate on his political campaigning.
