I have been using TB-500 for almost 6 weeks and can say that I'm very satisfied with the results.
My problem was tendonitis in both of my biceps so I decided to try out that TB-500 peptide because I read so many great reviews about it.
Protocol that I used
Week 1 - 5mg twice a week
Week 2-5 5mg once a week.
I plan to continue to use it at 1mg/week for maintenance till I run out of it.
I couldn't even train my biceps properly because of the pain I was getting but since the 4th week, I have successfully started to train biceps once again. I can still feel a slight pain while exercising but before I started the TB-500 it was simply unbearable. It was incredibly painful to do curls and I struggled even with exercises that don't train biceps directly like BB rows. Now I have no problem to do different types of curls and do 3 biceps exercises per workout.
I definitely wasn't expecting that TB-500 will provide such a relief for a tendonitis that I've been struggling for a few years already.
