Summary

How effective is Cartalax for long-term shoulder tendon and joint damage when combined with BPC-157, and what dosing schedule works?

One user with a decades-old BJJ shoulder tear and tendonitis reported near-complete relief after stem cells, PRP, TB-500 and lower-dose BPC all failed. Direct-site daily injections of 1–1.5 mg Cartalax mixed with 500–750 mcg BPC produced noticeable gains within days; the user plans to continue 30 days. Others asked for exact protocols but received only the single anecdotal report.

What this discussion establishesStill open

Whether the reported gains persist after stopping, optimal duration, or suitability for knees and elbows

Nothing here is advice.

At 54 I’ve had a shoulder problem from nearly thirty years of BJJ training and bad mechanics. A tear plus tendonitis left the arm unusable for a year. Stem cells and PRP eased pain briefly but it always returned. BPC-157 gave some help; TB-500 made my prostate symptoms worse so I quit that and kept adjusting the BPC. Cartalax has been different: the first use brought noticeable change and each following dose kept improving the joint. I’m now asking the shoulder to handle training loads it hasn’t seen in years.

What amount of Cartalax are you using? I’ve got some coming and two knee operations behind me that still need more work. Klow gave partial relief but I’m hoping for better results.

You said Cartalax changed everything yet gave no numbers on how much or how often you took it.

I’ve been checking into this for a troublesome elbow and knee. Can you share any dosage or schedule that worked?

Thanks for the reminder on dosing. I’m only five days in, which is why I posted early. I combine BPC and Cartalax in one syringe and put it right where the pain is. Even though it’s meant to be under the skin, I’ve found that going a bit deeper seems to help my shoulder more. I plan to run it for two weeks at 1–2 mg a day and so far have used up to 1.5 mg mixed with 500–750 mcg of BPC. That’s higher than most suggestions but lower amounts never moved the needle for me.

Yes, I followed the last suggestion there and used 1.5 mg BPC with 1 mg Cartalax. Because it feels like it’s clearing up long-standing issues I’m going to keep going for a full month.

That mix would probably burn going in. From what I’ve seen GHK-cu doesn’t do much for tendons, ligaments or muscle repair, so BPC and TB are still the only ones that show results.

Cool! I'd be curious to hear your thoughts once the cycle is over and some time has passed.

Thanks. My doctor mentioned the same thing. By the time it was found, I'd dropped around 15 pounds already, which made it stand out more.

Can you explain more about going straight into the muscle? I usually aim for a fatty spot around my shoulder and forearm, but I'm fairly lean and running low on spots. Sometimes hit veins and such. Direct into muscle would simplify things. Do you switch between different muscle spots? Happy to discuss some approaches if you have a moment. Right now I'm combining the blend with Cartalax and KPV in a single injection, mixing fresh each time without letting them sit. I also add an extra 1mg of the blend right at the trouble spot, plus my full 1mg each of BPC/TB/Cartalax and KPV in the stomach area.

Maybe! With the KLOW mix I typically stick to 1mg daily. For targeting a particular injury, I've used it alone up to 2.5mg per day. I've heard of people using as much as 4mg daily after a big injury or operation. Not recommending it either way, just sharing what others and I have done.

Sure thing! Thanks for the input. I've seen reports of folks using 1-2 per day for tough injuries too. We'll find out. I always forget how much patience is needed here 🤣

I came across some clips on the video site regarding muscle shot locations. Previously I mentioned them on a separate discussion board and believed they could come in handy over here as well. So there they are.
