I have the 4aderm from Avant labs. Fish oil and a daily multi-vitamin are the only supplements I take. I ejaculate about three times per week, and will continue to do so. I don’t see any reason why that would affect growth. Possibly if someone was ejaculating ten times per day they might run their body down and deplete Testosterone and GH levels. Three times per week feels healthy for me. Masturbation certainly doesn’t prevent teenagers from achieving penile growth.
