Read that article a few weeks ago, that’s why I also do my routine under the red light.
The thing is, i guess skin temperature might get up to 45 °C but I doubt that you can reach the same temperature underneath. I guess I can achieve 40 °C max. But that is just a speculation. And, I don’t really care because I currently see no other way in increasing tissue temperature to much more than that with another technique. So, this is the best-possible solution for me, currently.
Regarding gains, I believe this really helps. I have been doing that for about 4 weeks now. In the last 2 Month i’ve gained 0.6” in BPEL and 0.4” EG and i devote most of the gains to my penis being grilled to medium-rare under the redlight.
Regarding the nerves, can’t believe this temperature is damaging, everybody can by those lamps without any perscriptions. If it were dangerous, I guess you would not be able to get that stuff so easily.
So, I’m going to go on doing my routine under the red light. Feels good, and gains are good.
