I am on TRT at 200mg of Test C weekly. Initially I was injecting 100 mg every two weeks. The Dr Had me come in on the morning of the day of my next injection. I had blood work done and my test dropped from240 down to 103! Geezuus! Now im injecting 200mg weekly. Was curious about the diff between drawing blood a few days after pinning compared to the day of your next shot.
