Too much too fast?

Jay, GHK-CU and JFlex 9 Two things, your peptide book only gives dosage for the topical cream GHK-Cu. I assume for cartilage and joint issues we would want to inject? Is it still 0.21-0.84 mL same as topical? Also i went to TrueNutrition.com and did not see any product named JFlex 9. Could this be from another company or maybe discontinued? I sent TureNutrition.com a question asking about this product but have not heard back. Thanks for the help. This week I just started started taking testosterone and BPC157 recommended through doc at ways2well. She is the one that told me about you. I want to add ipamorelin and TB500. You think there is an issue of adding too much too fast?
