Upon trying your experiment for a short period I thought I might report what my results have been. I took 3mg of C daily and watched the effects it had on my routine results and sex life.
1st thing I found was that my wife complained about my being to big for a BJ. She has mentioned this in the past but this time I noticed that she was very much struggling with the added girth the C gave me. True I did have a noticeably greater flaccid hang and when I tried to mount my PEWeights, the puffiness of my flaccid caused me to experience skin pinches. At the same time I noticed a definite loss of flaccid length. This caused me to drop from my normal 4 rings to 3.
Within the time frame of taking the C I did a pump session to take a measurement and found that thereto I lost length barely reaching 8.5” and it was not as comfortable a pump as I normally experience.
Subsequent to that I stopped taking the C and within two days my flaccid length returned allowing 4 rings again and last night no complaints from the wife. I also got back in the tube and registered 8 5/8 length.
So from my perspective the C had a negative affect on my progress. I’ll probably use C on occasion but not on a regular basis.
BTW: 6mg of C gave me headaches.
