I’ve ordered a couple times now and the process is really easy once you’ve done it once. Was impressed with the packaging and it showed with absolutely everything. Needles, swabs, instruction card, gel pack and a travel case. What I really want to give credit where credit is due. I ordered a SS-31 and they realized they missed the instruction card and emailed it to me right away, I got the instruction card before the package. It’s absolutely an A+ especially on customer service.

I had a bad shoulder so did some research on this. I ordered this with BPC 157 and the combo was great. Within a week my pain was gone in my shoulder. Great product!

I’m pretty active and was looking for something to add to my recovery routine. Since starting TB-500, I’ve noticed I don’t feel as beat up after harder days and I’m able to get back to being active sooner. On top of that, the service has been excellent. My order arrived quickly and the communication from the company was great.

I’m very active, so I was curious to see how I’d get along with TB-500. This one is staying in the rotation with BPC.
