I have just completed 9 weeks of radiation and a 6 month hormone shot to comabt Prostate Cancer. So far we have been unsuccessful with Trimex. The 1st time in the Drs office with insulin syringe and 5 I did ok. Our 1st time we increased to 10 with no effects but burned. 2nd time up to 15, bruised, no results, again at 15, no results and felt like it was a good hit. The next time at 20 good hit, semi hard, not good results, are we just off on the site?
