I have for a long time used MOS-RED after my sessions for faster healing and to keep the discoloration at bay in my glans from stretching with
LENGTHMASTER 3. Without MOS-RED it would not work for me. I have discovered more beneficial things as well, like better sleep, more relaxed in my body, faster hair growth probably

...
Now I have some diffrent problems due to much bundles of my penis when stretching. I get fluid retention from staying clamped down in the chamber fron just 5 minutes. So I'm now using MOS-RED during my sessions, and between my sets, and after my sessions in order to reduce this fluid retention build-up. It works very well.
Do you have MOS-RED, or a different kind of light. There are 2 wavelengths that you want. You don't want just the red ligth. You need near infrared as well in order to maximize the benefits.
Hope this helps.
