TB-500 and what to add to the stack: zinc, vitamin C, and collagen
TB-500 shows up in a lot of protocols paired with zinc, vitamin C, and collagen, and that pairing isn't random. Short answer: take TB-500 for the systemic repair signaling, and add zinc, vitamin C, and collagen because those three supply the raw materials your body uses to actually rebuild tissue once TB-500 sets the repair process in motion.
What TB-500 actually does, and why it can't finish the job alone
TB-500 is the synthetic version of thymosin beta-4, and its core job is actin sequestration. Actin is the protein that forms a cell's internal scaffolding, and TB-500 grabs the free-floating monomers and releases them on demand, which is what lets repair cells physically crawl toward damaged tissue. That crawling is the whole reason a cell can reach an injury site in the first place. TB-500 also drives new blood vessel growth into the repairing area, and it turns down the inflammatory and fibrotic signaling that would otherwise leave you with disorganized scar tissue instead of properly rebuilt tissue.
None of that is building. TB-500 gets repair cells to the injury and clears the inflammatory clutter, but the actual construction work, laying down new collagen, closing off vessel walls, restoring skin and tendon and connective tissue, runs on raw materials TB-500 never supplies. I see this gap constantly with clients who run a clean TB-500 or Wolverine cycle and still recover slower than expected, and the answer is almost always upstream of the peptide.
Zinc: the mineral collagen remodeling can't run without
Zinc is a cofactor for well over 300 enzymes in the body, and a meaningful chunk of them sit directly in the wound-healing pathway, including the matrix metalloproteinases that remodel damaged tissue and the processes that support collagen cross-linking. Low zinc status shows up clinically as slow-healing wounds, and it's a common gap in anyone already dealing with a soft-tissue injury, since poor appetite, inflammation, and GI stress during recovery all drain zinc faster than usual.
I use 15 to 30 mg of zinc (picolinate or bisglycinate absorb better than oxide) daily alongside a TB-500 cycle. If you're also running anything copper-heavy, GHK-Cu being the obvious example, keep an eye on copper intake too, since sustained high-dose zinc on its own can drag copper down over several weeks.
Vitamin C: the step collagen synthesis cannot skip
This one is closer to a hard bottleneck than a "helps a little" story. The two enzymes that stabilize collagen's triple-helix structure, prolyl hydroxylase and lysyl hydroxylase, require vitamin C as a direct cofactor. Without enough of it circulating, the collagen your fibroblasts try to lay down comes out structurally weak and gets broken down almost as fast as it's made. Scurvy is the extreme end of this, wounds that reopen and connective tissue that falls apart, but you don't need to be scurvy-deficient to be running below what active tissue repair actually demands.
500 to 1,000 mg of vitamin C daily, split into two doses, is the range I see used alongside a repair-focused peptide protocol. Splitting the dose matters more than the total, since vitamin C isn't stored in meaningful reserves and gets used up fast when synthesis is running hot.
Collagen: giving the body the substrate itself
Zinc and vitamin C support the enzymes. Collagen peptides, or a full amino acid profile from bone broth or a hydrolyzed collagen powder, give the body glycine, proline, and hydroxyproline, the actual building blocks those enzymes work on. TB-500's angiogenesis signal opens the door for repair cells to reach the site, and the faster dermal healing seen in animal wound models reflects new tissue actually forming there, tissue that needs a steady supply of collagen precursors to be built from at all.
15 to 20 grams of hydrolyzed collagen or collagen peptides daily is a reasonable target, ideally taken with your vitamin C in the same sitting since that's when the synthesis enzymes are working on the material you just supplied.
Running it as one stack
In practice this looks less like three separate supplements and more like one small routine layered on top of your TB-500 dosing: collagen and vitamin C together, once a day, and zinc at a separate meal so it doesn't compete with other minerals for absorption. None of this needs to be perfectly timed around the injection itself. What matters is that the raw materials are consistently present while TB-500 is actively signaling repair, which for most protocols is the full length of the cycle.
Now the part my lawyer makes me say, and he's right to make me say it: the doses and schedules here are for educational and informational purposes only.

Zinc, vitamin C, and collagen aren't going to make a peptide protocol succeed on their own, and TB-500 does what it does mechanically whether or not you take them. What changes is how completely the tissue rebuilds afterward, and that comes down to whether zinc, vitamin C, and collagen are actually on hand when TB-500 opens up the repair window.
Frequently asked questions
Do I actually need zinc, vitamin C, and collagen with TB-500, or is that just marketing?
TB-500 mobilizes repair cells and opens blood flow to the injury site, but it does not supply the raw materials those cells build new tissue from. Zinc and vitamin C are cofactors your body's collagen-synthesis enzymes cannot function without, and collagen itself supplies the amino acids those enzymes work on. Skipping them does not make TB-500 fail outright, but it does slow down how completely the tissue rebuilds.
How much zinc and vitamin C should I take with a TB-500 cycle?
A common range is 15 to 30 mg of zinc (picolinate or bisglycinate) and 500 to 1,000 mg of vitamin C daily, split into two doses. These are the amounts people running a TB-500 protocol commonly use, not a clinical dosing standard, since there is no dedicated trial pairing TB-500 with these specific supplements.
Can I just eat more protein instead of taking collagen peptides?
Whole protein gives your body the amino acids to build collagen from scratch, so solid protein intake matters regardless. Collagen peptides specifically supply glycine, proline, and hydroxyproline in the ratios collagen actually needs, which is why many people layer both rather than picking one over the other.
Does TB-500 work without any of these supplements?
Yes. TB-500's core mechanisms, actin-driven cell migration, new blood vessel growth, and reduced fibrotic signaling, happen regardless of your supplement intake. Adding zinc, vitamin C, and collagen changes how completely and durably the tissue rebuilds afterward, not whether TB-500 does its job in the first place.
