BPC-157 TB-500 Local Injection Site Necessity

So I've got tendonitis basically everywhere at this point. Started in my elbows which mostly healed with time and loading, but it's been over a year and still not 100 percent. Now it's in my feet (I have accessory naviculars in both, worse on the left) and in my thumb from old injuries, which is wrecking my grip strength at work. Found a source with COAs and third party testing so I feel okay about quality. My question is more practical, do BPC-157 and TB-500 actually need to be injected right at the painful spot to work? My feet and thumb seem like brutal places to try to pin. Trying to not waste product if I don't have to.

Currently typing with correct posture. Probably.

The theory behind local injection is that you get a higher concentration right where the tissue damage is, but both peptides also act systemically once they're in you, people report benefit from sub-q in the belly or thigh for injuries nowhere near there. For something like a thumb I'd honestly do systemic sub-q rather than trying to get a needle into that tiny joint space repeatedly. Loading is still what drives the tendon remodeling, the peptide is riding alongside that work, not replacing it.

Load is the drug with the best data.

Short half life is the argument people make for local injection, get it there before it clears. Whether that matters clinically in a human versus a rat with a surgically created lesion is a different question nobody's answered.

Preclinical is not a promise.

I've logged both ways over the years. For my elbows I do local sub-q right next to the tendon, for my Achilles I just do systemic because trying to hit that area precisely was a nightmare and bruised like hell. Honestly can't tell a difference in my own spreadsheet between the two approaches for recovery timeline, both landed around week 3 to 4 for noticeable change. For a thumb specifically I would not try to pin directly into it, way too much nerve and tendon packed in a small space, do it systemic.

Measure it or it did not happen.

Whatever you do with the peptide, your thumb and feet still need progressive loading or none of this sticks long term.

You cannot inject your way out of a bad program.

From a pharmacy standpoint, reconstituted peptide should be used within the same beyond use window regardless of where you're injecting it, location doesn't change storage or stability. If you're drawing small volumes repeatedly for a tiny area like a thumb, just be careful with sterile technique each time, that's where people run into trouble, not the injection site choice itself.

If the vial looks cloudy, the answer is no.

My PT recommended systemic for my patellar stuff, said pinning directly into the tendon itself is asking for trouble anyway.

Isometrics before ice. Every time.

Following this, I've been wondering the same thing for my hamstring. Glad to hear systemic isn't a downgrade.

Still here. Still slow.
