No way was i ever going to sign up for the " common cold cure" sessions touted on routine orders at regular intervals by the Porton Down set in the 1960s-80s, or the "trials" held at the NBC school in Winterbourne Gunner, with the promise of additional leave and duty pay for those volunteering. But things seem to have changed for the better inducement wise, a nephew in the US has been looking for ways to pay towards his college fees for next term, saw an ad for medical trials, put his name in, full free health check, bloods etc, and an evaluation by a shrink? Got the green light. Now the good part! 16 days in a private clinic/ health spa, all inclusive, the product/drug the male contraceptive. Rules: you must not leave the premises( no problem) Provide 2 semen samples per day( again no problem, he will simply have to cut down a bit on his regular routine) at the end of the trial period you get paid..$7250 tax free. Would you sign up for one of these/ or have you already done it? That's a fair old lump of bucks for being a tosser, but some of the horror stories over the years would deter me, but there again??
