Quick Review: Prungo FluxGo Red Light Therapy Module
Jim’s Tech Talk
By Jim Langley
I’m not a doctor and I have no knowledge of the science or studies behind red light therapy. I also haven’t done any research to either back up the claims of red light therapy proponents or dispel them.
What I can tell you is that I personally tried this company-provided sample Prungo FluxGo Red Light Therapy Module (RLT300) that I’m reviewing here and it was effective on the tennis-elbow pain I suffer from (my second sport is table tennis).

From Pittsburgh to Washington, D.C., hundreds of miles of car-free riding, I hemmed and hawed over planning my own bikepacking adventure. Go solo? Book a tour outfitter? Some hybrid? I spent an embarrassing amount of time deliberating. Read more.

Question: Is testosterone replacement therapy acceptable for recreational cycling? —Allen J.
RBR’S STAN PURDUM REPLIES: I assume you specified “recreational cycling” since in professional competitive cycling, using testosterone is considered an anti-doping rule violation.
