Since BPC is pretty much the backbone of this board, here is where the actual data stands without the hype. What we have documented: - Decades of rodent work, mostly Achilles transection and tendon-to-bone models. Consistent hits across the board: better load to failure, higher stiffness, solid histology. - In vitro tendon fibroblast data showing faster migration, cell survival under strain, and GH receptor upregulation. - A legit mechanism: VEGFR2-driven angiogenesis targeting the hypovascular environment that makes tendons take months to heal. Where the real gaps lie: - Solid PK profiles for sub-q or oral protocols people actually run. - Accurate dose translation from animal models down to standard human pins. - The 2026 controlled study currently enrolling is for acute hamstring strains, not chronic tendinopathy. The mechanism is solid and the tissue data is impressive, but scaling it to an n=1 cycle requires realistic expectations and proper PT load. Ignoring the mechanism is stupid, but expecting a magic pin without doing the work is just as dumb.

Preclinical is not a promise.

Great summary. This is what I tell patients: if you have an actual diagnosis, a structured loading program you stick to, and realistic expectations, it can be worth discussing with a prescriber. But it is never a substitute for progressive load.

Load is the drug with the best data.

Question from my tracking log on this. Based on the angiogenesis mechanism, should we expect a bigger response in a hypovascular mid-portion Achilles versus lateral epicondyle tissue? In my logs, my elbows barely moved the needle compared to my Achilles, but I also loaded the Achilles much more strictly. Hard to isolate the variable.

Measure it or it did not happen.

Mechanistically plausible, but in an n=1 study design the loading difference is a massive confounding variable. You cannot isolate it.

Preclinical is not a promise.

Appreciate the balanced view. My surgeon basically shrugged and said no human data, not obviously dangerous, go ask a prescriber. Sums up this whole topic.

Two years of patience beat six months of panic.

Spot on about the 2026 trial. An acute hamstring strain is totally different biology from chronic degenerative tendinopathy. When I was rebuilding my Achilles for marathon training, muscle vs tendon tissue healed on completely different timelines.

Slow is smooth. Smooth is 5k pace eventually.

Exactly. People will extrapolate a hamstring strain trial to chronic tendinopathy the day results drop. Guaranteed.

Preclinical is not a promise.
