Anyone tried pentosan for a cranky knee? Curious about real timelines

Got a left knee that's been bugging me for months. MRI showed some cartilage thinning and a small bone marrow lesion under the medial side. My ortho basically said "lose weight and do PT," which yeah, I'm doing both, but I'm looking for something more targeted while I rebuild.

I keep coming across pentosan polysulfate in older OA literature, specifically the work showing it can actually stimulate proteoglycan synthesis rather than just mask pain. The DMOAD angle is what caught my eye. Cartrophen-style weekly SC injections seem to be the protocol I've seen most, but oral is way more available here.

For anyone who's actually run it, what kind of timeline are we talking before the joint felt different? And did SC vs oral make a noticeable difference for you? I know the maculopathy thing with long-term high-dose oral has me a little spooked, but the cartilage data is hard to ignore.

Also, did anyone pair it with BPC-157 or TB-500, or is that overkill? Trying to figure out a sensible stack rather than throwing everything at it.
