I guess that's a good/bad sign?
I suggest you read more about the lasers, if nowhere else then on this forum. You'd know the answer to this question even if you'd done brief research. Most people advocating for the laser state that first spikes are good. Even I get small, maybe 20% intensity, spike, after all these years, while but only while I do the laser and not anymore after it. I think some of my latest posts on the laser threads have been good, some tidbits and information on what I've learned.
I mentioned also in one of my latest posts after a poster in a laser thread got a major spike, that I started with 5 minutes of the laser myself. I had the foresight to do that even over 2 years ago when nobody mentioned it. It's good to start your supplements slow too. I take a spec of them starting out, there's no downside to this and major upside of when you get bad side effects not ruining yourself were you to get bad side effects.
Definitely don't do the 808nm 30 minutes like you did the 660nm, even though that's what Konftec suggests. Not that it'll damage you but it'll freak you out more if even the 660nm did, because the 808nm is almost twice as powerful. So yeah I'll reiterate what I mentioned to my first post to you, you need to do more research. I spent a lot of time reading about this treatment before I even purchased the laser. It's just impractical also to type out everything for every new person again and again.
EDIT: Reading back now, I might have been a bit blunt in my last post. I didn't mean to put you down or anything, it's just the way I write. I'm thinking about making a post or maybe even a thread, probably a post though, where I can direct people to that has all my suggestions about the lasers in a cohesive and brief way.
