BPC-157 for wrist injuries: what the evidence actually says

What did @stri_king actually say?

The creator broke down wrist anatomy for a follower asking about wrist pain, then pitched a recovery protocol built around nutrition and movement. Specifically, they recommended "bone broth," "sleep potatoes," and something called "sourdene" as foundational healing tools, describing them as "wonderful for the body and healing properties." They also recommended tendon gliding exercises, framing movement plus nutrition as the primary mechanism through which wrist tendons and ligaments repair. The anatomy walkthrough, covering tendons, ligaments, and tendon sheaths, was reasonably accurate in framing. The recovery advice is where things get murkier.

It is worth noting the creator appears to be a sports performance coach, not a licensed clinician. That context matters when evaluating how much weight to give the specific product recommendations made here.

Does the science back this up?

Partially, yes. The connective tissue nutrition angle has real support, but the specific foods named are a mixed bag. Bone broth contains glycine and proline, amino acids used in collagen synthesis, and a 2019 study by Shaw et al. in the American Journal of Clinical Nutrition found that gelatin supplementation combined with vitamin C and exercise did increase collagen synthesis markers. That is a real effect. Tendon gliding exercises also have solid rehabilitation evidence behind them, particularly for conditions like de Quervain tenosynovitis and carpal tunnel syndrome. A 2014 review by Michlovitz et al. in the Journal of Hand Therapy supported their use in wrist and hand rehab protocols.

However, the claim that movement and nutrition alone will drive healing glosses over severity. A partially torn ligament and an inflamed tendon sheath require very different interventions.

What did they get wrong (or right)?

The anatomy framing was mostly right. Tendons connect muscle to bone, ligaments connect bone to bone, and tendon sheaths do act as lubricating tunnels. That is accurate. Tendon gliding as a rehab tool is also a legitimate recommendation with clinical backing.

What they got wrong starts with "sourdene." That word does not correspond to any recognizable supplement, food, or compound. It may be a mispronunciation of sardines, which do contain omega-3 fatty acids with anti-inflammatory properties, but as stated it is unverifiable. "Sleep potatoes" is similarly unclear, possibly referring to potatoes eaten before bed for their effect on sleep quality via tryptophan pathways, but this is speculative. Recommending foods by names that do not clearly map to real things is a problem in a health context.

More substantively, the creator presents this protocol as a general solution to wrist pain without any screening for injury severity. Wrist pain in boxing or MMA can involve scapholunate ligament tears, TFCC injuries, or fractures. Telling someone to eat bone broth and do tendon gliding when they may have a structural injury could delay necessary care.

What should you actually know?

Connective tissue repair is genuinely slower than muscle repair because tendons and ligaments have poor blood supply. That is real physiology, and nutrition that supports collagen synthesis, specifically glycine, proline, hydroxyproline, and vitamin C, does matter. A 2017 randomized trial by Shaw et al. in the American Journal of Clinical Nutrition confirmed that 15 grams of gelatin plus vitamin C before intermittent exercise boosted collagen synthesis in healthy males. So the bone broth direction is not wrong, just imprecise.

Tendon gliding is a legitimate tool used by occupational therapists and hand surgeons in structured rehab. The evidence base is real.

What this video cannot do is replace a differential diagnosis. If your wrist pain is sharp, persistent, or came from a specific impact, imaging is often necessary before any rehab protocol makes sense. Peptide therapies like BPC-157 are being studied for tendon and ligament repair in animal models, but human clinical trial data remains limited. That is a separate conversation requiring a licensed provider, not a TikTok protocol.
