Maybe I'm missing something, but you gave yourself a double dose (a full day's worth of your current protocol, which is normally split into two doses), then got tested two hours later, and are now using that as a cautionary tale for high DHT? That would be like someone on 200 mg of testosterone giving themselves 400 mg, then testing at the peak concentration, then being surprised that their lab results were far out of range.
OK, this might need some more context. Because of a varied lifestyle, there are some days when I'm unable to apply a pm dose so I do both doses am. I can't tell the difference the additional two clicks on my forearms makes. I'm confident the overdosing and resulting jitters were coming from higher absorption through my scrotal tissue either am or pm. I think I was looking subconsciously for the worst case on how high my DHT would go. I don't have the means to do hourly tests of my DHT through the day, but i understand the leaders of this forum are intent on looking into this topic and giving members some much needed information. The encouraging part of the story is that scrotal application might be a way to find my dialed in zone (eg 1 click scrotal pm or EOD) that avoids a needle and mainlining who knows what awful carrier + T directly into my bloodstream. We just need to be aware of this additional androgen compound, and more research is needed on what adverse effects out of range levels might cause especially to heart function.
