Has anyone used TB-500 for hair loss?

There's a real study behind why people say this, mouse model, thymosin beta-4 pushed follicle stem cells out of the resting phase into active growth and the treated mice grew thicker coats faster than controls. It's a legit finding. But it's mice, and going from mouse follicle stem cells to a guy injecting himself and expecting a hairline back is a pretty big leap nobody has actually tested in humans.

I ran TB-500 for like 4 months for my hamstring and my wife swears my hair looked less thin in pictures from that period. I genuinely can't tell if it's the peptide or just because I finally started sleeping normal hours again.

Every guy who's balding wants the one weird trick. I'll believe it when someone posts a real before and after that isn't just better lighting.

This is interesting to me because GHK-Cu gets talked about for hair too, the copper peptide stuff has actual old data on follicle size in vitro. Curious if anyone's tried stacking the two specifically for hair rather than just tendon stuff as a side bonus.

The mechanism people point to makes sense on paper, TB-500 drives new blood vessel formation and wakes up dormant stem cells, and follicles do need both of those things to cycle properly. The problem is that's true of a lot of tissue in the body and it doesn't automatically mean it'll behave the same way in a human scalp as it did in a mouse. If hair is the actual goal I'd put money on minoxidil and finasteride first, they've got decades of people actually using them for that specific purpose.

Not going to lie I started taking monthly hairline photos back when I started my elbow log because I'm that guy. 14 months in, no meaningful change either direction that I can point to. Small sample size of one though.

Seasonal shedding is a real thing too, I lose way more hair in the shower every fall regardless of what I'm running. Hard to separate peptide effect from that noise honestly.

Slightly off topic but one of my volleyball girls started losing hair from stress this season and I keep wondering how much of these anecdotal wins are just people's cortisol finally chilling out once they feel like they're doing something proactive for their body.

Same boat as tendon_tinker honestly, ran it for a joint thing, watched my hair the whole time out of curiosity, couldn't tell you if anything changed. Too many variables in a normal life to isolate one peptide.

Okay this is helpful, sounds like the honest answer is maybe placebo maybe seasonal maybe nothing. Guess I'll keep my minoxidil going and just enjoy the elbow benefits for now.
