I appreciate the included certificate to verify content and potency as I'm repurposing for my personal choice to treat the big C. After chemo, radiation and surgery are exhausted opportunities, the oncologist has given me 6 mths. When they tell you to enjoy the time you have left and you've used up your options, there's nothing to lose. But perhaps this can extend my days somewhat. I'm not expecting a miracle since I'm already stage 4, but along with fenben it could be my last chance. Thanks again to you folks at RT for the prompt shipping and the Vanguard lab cert of analysis.
