I'm replying to myself here. Came across a forum thread that pointed me toward a guide. Thanks, me!

For the most part, I haven't used peptides before. GLP-1 agonists worked for me when it came to losing weight. After spending some time reading around here, I went ahead and purchased BPC157+TB500 for a chronic achilles tendonitis that has bothered me for several years. An MD has diagnosed and treated it (orthotics, taping, PT), yet whenever I believe it has finally cleared up, it returns, often right in the middle of a CrossFit workout! It's a frustrating and painful issue that I want to get rid of completely.

Could someone share a dosing and frequency plan that would be reasonable for this? Is it even acceptable for me to ask? I'm new around here and am trying to figure out what topics I can and can't post about.

What I purchased is a lyophilized vial, 20 mg in total (10 mg BPC157 plus 10 mg TB500 combined).

I appreciate all the knowledge people share on these forums!
 
You're going to need a bigger boat, I can tell you that. My own tendonitis protocol began at 2.5mg TB500 taken twice per week, alongside BPC-157 at 500mcg that I tapered upward until reaching 1mg daily around week 4. Come week 5, I moved to 1mg TB500 every other day while leaving the BPC dose unchanged. Noticeable improvement didn't really show up for me until roughly week 5. This cycle will total 50mg TB500 and 100mg BPC-157 by the time I finish.
 
Beyond whatever protocol you're following, consider putting a heel insert in your shoe. A relative of mine works as a podiatrist, and that's the top recommendation they give for this issue. The tendon is being stretched too far and needs some relief. My husband dealt with the same thing (he's a frequent runner), and it worked for him. Best of luck & hope you're feeling better soon!! 🙂
 
Peptides for 5 weeks? Hmm... With 5 weeks of correct nutrition plus supportive exercises—and no peptides at all—you can see major improvement in most tendons.

What might be possible, I wonder, with a proper nutritional support regimen combined with peptide support?

Rule 1. Taking ibuprofen while this repair is underway will prolong the tendon's healing time.
 
1. Collagen is part of my daily routine.

2. I've switched to footwear with a noticeable "drop," which reduces strain on the tendon.

3. Regarding how much and how long, what Pete 369 outlines seems like A LOT, but on the other hand tendon issues are tough and mine has been chronic--flaring up and settling down for years. My first bout came during COVID.

I'll experiment with plenty of things to finally kick this for good!
 
This is a tough one, no question. You'll need:

1. Nutrition aimed at the problem

2. A program built around physical therapy methods that have evidence behind them.

3. Extra help, like the footwear you mentioned.

4. Is it possible to switch your training to something that spares your tendons?

I'd be digging into how to boost circulation to that tendon, while going all in on everything listed above.

Honestly, reading what you've described, I'd probably be considering peptides too if this were happening to me. If a solid peptide protocol came to mind, I'd pass it along. Unfortunately, I've got nothing.

Have you checked whether a skilled Functional Medicine Doctor with sports injury and peptide background is available to you?

After writing that, I wondered: does a doctor like that even exist?

Wow!!! There are a few in my region, and good old google (haha) told me the term for what we want is... an orthopedic sports specialist. If that's not something you've done yet, it could be worth looking into. One near me even advertises in-office peptide support.

I hope at least some of this helps and isn't just stuff you've already been doing. Good luck, and I hope one day you'll post an update about how you got past this and beat it.
 
I've consulted a range of practitioners—a functional medicine specialist, an orthopedist, and others—and the individual who has proven most useful is a podiatrist right here in my community. Over the course of 6 years I've cycled through many different treatments for this (not nonstop, but on and off repeatedly). Having it flare up now and then isn't catastrophic, but given that I've already tried everything else with reasonable evidence behind it, why not give peptides a shot. That's the part that's new to me.
 
Look into the work of Dr. Keith Baar. When it comes to tendon recovery, he is among the most trusted authorities, and he offers quite particular guidance for what you're dealing with.

Symptoms of severe tendinopathy should never be brushed aside. Healing a damaged tendon is far simpler than bouncing back from an operation for a full rupture, something I discovered only after it was too late.

Forcing your way through the pain is a serious error, and high load concentric movements or sports involving rapid loading will work against you. What tendons respond to most effectively is high load isometrics or negative sets, paired with a relatively low overall workload and plenty of rest so healing can occur. Also, be sure your protein intake is sufficient.
 
Bioexplorer, thanks — there's another source I can add to the material I've been collecting.

Dr. Keith Baar’s tendon repair and strengthening approach focuses on short, controlled isometric loading and adequate rest periods to stimulate collagen synthesis. His research at UC Davis shows that tendons respond quickly to mechanical load and become refractory within 10 minutes, meaning more exercise does not equal faster healing.

The Core Protocol

    • Isometric Holds: Perform 3 to 5 sets of slow, steady muscle contractions holding a position (like an isometric lunge) for 30 seconds per hold. [1, 2]
    • Low Duration: Keep total loading time under 10 minutes per session to maximize cellular signaling without causing micro-damage. [1, 2]
    • Rest Intervals: Allow at least 6 to 8 hours of rest between loading sessions to give the connective tissue time to synthesize new collagen proteins. [1, 2]
    • Pain Monitoring: Avoid sharp, stabbing pain; aim for a dull tension or warm muscle-burning sensation in the targeted area. [1]

Nutritional Support

    • Collagen and Vitamin C: Consuming gelatin or hydrolyzed collagen combined with vitamin C approximately 60 minutes before the short loading session has been shown in his lab to double collagen production in connective tissues.

Here's a picture of the heel lift so you can see what it looks like
