I'm 55 and healing like garbage, is this just age or am I doing something wrong?

Age slows blood flow, but it isn't an excuse to sit around complaining. BPC speeds up the angiogenic response, but tendon remodeling is a 12 to 16 week deployment minimum. Four weeks in is barely phase one. Are you hitting actual heavy slow resistance or just floating around with light resistance bands?

How's your sleep and consistency? Peptides aren't going to fix five hours of broken sleep and sporadic loading.

Sleep is locked in at 7 to 8 hours. I don't miss rehab sessions. Three sets of heavy eccentrics twice a week, strictly tracked.

You're overthinking the timeline. At 50+, baseline extracellular matrix turnover is significantly slower due to lower endogenous growth factor output. BPC-157 upregulates VEGFR2 and fibroblast migration, but four weeks is still early collagen synthesis territory in vivo. Connective tissue doesn't care about your impatience. If you want faster systemic remodeling, add TB-500 at 2.5mg twice a week to hit actin cell migration while keeping the BPC local.

This. Stacking TB-500 with BPC was night and day for my bicep tendon. BPC alone felt slow until I added the TB.

Also look at your systemic inflammation and protein intake. Age makes us less efficient at amino acid uptake. You need raw materials to lay down new collagen while BPC signals the repair.

Eating 180g protein daily, plenty of collagen peptides too. Has anyone added GHK-Cu or Sermorelin to this kind of stack for systemic speed?

Don't start pinning five different vials before you let the core stack work. BPC and TB-500 is the standard protocol for a reason. Keep pinning local, add the TB, and stick to the loading parameters.

That post-rehab ache you're feeling isn't necessarily a bad sign either. When I went through my knee rebuild, I kept mistaking remodeling pain for tissue damage. Tendons adapt under tension, and that ache is often just collagen fibers remodeling under load.

Exactly. Tenocyte proliferation and matrix reorganization naturally trigger localized inflammatory signals. That ache is literally the signal that the tissue is adapting to the mechanical load.

That's placebo worry talking. Measure your progress by loading capacity and range of motion, not by whether the tendon aches the day after.

That actually makes a lot of sense about remodeling pain versus damage. I'll add TB-500 to the cycle starting this week and give the eccentric loading another month before I stress out.
