Diclofenac topical gel while running BPC-157, does the NSAID effect blunt healing?

Question

So I've been using Voltaren gel on my shoulder when it flares up, usually after training days. Just 1% diclofenac, maybe 3-4 times a day on bad days. Anecdotally it takes the edge off pretty well and I like that it stays local instead of messing with my stomach like oral NSAIDs would. But I'm also running BPC-157 subQ for the same shoulder and now I'm second-guessing myself. The whole point of BPC is promoting tendon healing, and if diclofenac is suppressing prostaglandins locally right at the joint, could that interfere with what the peptide is trying to do? I know oral NSAIDs get flagged for potentially slowing soft tissue healing, but topical is supposed to be mostly local with minimal systemic spillover. Still, the local tissue concentration at the shoulder is probably meaningful. Has anyone here run topical diclofenac alongside BPC-157 or TB-500 and felt like it slowed their recovery down? Or noticed no difference at all? I'm trying to figure out if I should drop the Voltaren on injection days or just not worry about it. Anecdotally my shoulder feels about the same either way but I'm only a few weeks in so hard to tell.

That spreadsheet approach is smart, I should probably start doing that instead of just guessing. The lower pain but similar stiffness thing is interesting, kinda sounds like the gel is doing its job on pain without necessarily blocking the repair process. Did you end up tapering off the Voltaren after that first week or did you keep using it through the whole BPC run?

That tracking approach is smart, the pain vs stiffness split is a pretty useful way to think about it. Topical diclofenac systemic absorption is low compared to oral, so even if there's some local prostaglandin suppression it's probably not enough to override what BPC is doing at the tissue level, at least that's my take on it. I'd lean toward using the gel when you need it and not overthinking.

I ran voltaren gel on my elbow while doing bpc-157 subQ for the same joint, probably 2-3x daily for the first week or so. Ngl i was worried about the same thing. My recovery felt roughly the same whether i used it or skipped it, but that's just my own experience and could be placebo either way. The thing that actually helped me decide was tracking pain scores and ROM daily in a spreadsheet. The voltaren days had lower pain but similar stiffness, which made me think it was just masking symptoms rather than interfering with healing underneath. Hard to know for sure though? One thing worth considering, topical diclofenac systemic absorption is way lower than oral, like 5-10% i think? So the prostaglandin suppression is mostly local to the skin and superficial tissue, not necessarily deep in the tendon where bpc is doing its thing. Maybe try dropping it for a week and see if your pain scores change? That'd give you a cleaner read on whether the bpc is doing the heavy lifting on its own.

Thanks for the take, I like the pain vs stiffness split idea. I’ll start logging when I use the gel and how the shoulder feels after each BPC shot to see if there’s any pattern. Do you usually apply the gel before or after your peptide dose?
