Full disclaimerTB-500 Loading + Maintenance Protocol
Standard loading + maintenance cycle: 4 weeks at full dose (2x/week), then 4 weeks maintenance at half dose (1x/week). Systemic — injection site does not matter.
Peptide Schedule Research TeamReviewed Apr 20261 Citation
For systemic injury recovery and tissue repair with front-loaded healing support.
What This Protocol Does
TB-500 (thymosin beta-4 fragment) promotes cell migration, reduces inflammation, and supports tissue remodeling throughout the body. Unlike BPC-157, TB-500 works systemically regardless of injection site. The loading phase (4 weeks at full dose) saturates tissue levels, then maintenance sustains the healing environment. Phase 2 cardiac data showed improved ventricular function after myocardial infarction.
Who Should Use This
For beginners and intermediate users with chronic injuries, post-surgical recovery, or widespread inflammation. No prior peptide experience required, though understanding subcutaneous injection technique is expected. Avoid if you have active cancer (TB-500 promotes angiogenesis). Use caution if taking anticoagulants, as TB-500 may increase bleeding risk.
What the Research Says
Thymosin beta-4: First-in-human Phase I safety study (PMID 34346165, 2021) confirmed tolerability. Phase 2 cardiac trial data showed improved left ventricular function after acute myocardial infarction. Preclinical evidence demonstrates accelerated wound healing (Malinda et al., J Invest Dermatol 1999, PMID 10469297), anti-inflammatory effects, and corneal repair. The loading/maintenance dosing pattern comes from community protocols backed by thousands of anecdotal reports. TB-500 is the synthetic fragment of naturally occurring thymosin beta-4.
Important Notices
- No human clinical trials for TB-500 fragment specifically
- Promotes angiogenesis — contraindicated with active cancer
- May increase bleeding risk with anticoagulants

BPC-157 Conservative Healing Protocol
BPC-157
Conservative 6-week healing protocol using beginner-tier dosing. Inject near injury site for local repair or abdomen for systemic/gut effects.
Healing Stack: BPC-157 + TB-500
BPC-157 + TB-500
Gold-standard healing combination. BPC-157 for local tissue repair + TB-500 for systemic healing. 6-week protocol with TB-500 loading then maintenance.
Wolverine Stack
BPC-157 + TB-500 + Ipamorelin +2
Five peptides, three sub-stacks, and a torn hamstring that started it all. Ben Greenfield published full dosing for BPC-157, TB-500, ipamorelin, tesamorelin, and GHK-Cu after using the combo to recover from a persistent upper leg injury. The healing duo (BPC-157 + TB-500) can be run alone; the GH pair (ipamorelin + tesamorelin) adds recovery optimization at bedtime. Budget $400-800/month and plan for 4-12 weeks on, equal time off.
Never Get Sick Stack
TB-500 + Thymalin + LL-37
Three peptides, three different cycle lengths, one goal: stop getting sick. Greenfield pairs TB-500 (3 months on, 3 off) with Thymalin (3-10 day bursts every 6-12 months) and LL-37 (4-6 week antimicrobial cycles). Each targets a different layer of immune defense. Warning on LL-37: Herxheimer reactions are common in the first two weeks if you have SIBO or gut dysbiosis.
Dr. Koniver's GH Secretagogue Bedtime Stack
BPC-157 + Ipamorelin + Tesamorelin
One syringe, three peptides, taken at bedtime. Dr. Koniver confirmed on Huberman Lab Ep 197 that he combines BPC-157 (500mcg), ipamorelin (100mcg), and tesamorelin (2mg) in a single subcutaneous injection. Schedule is 5 days on, 2 off. No food for 45 minutes before. The single-syringe detail settled a long-running debate about whether these peptides could be mixed safely.
Dr. Edwin Lee's BPC-157 Knee Protocol (Clinical Trial)
BPC-157
The only peer-reviewed human BPC-157 clinical trial, published in Alternative Therapies (2021). Dr. Edwin Lee injected 4mg BPC-157 directly into knee joints. Seven out of 12 patients reported pain relief lasting 6+ months from a single injection. The route is intra-articular, not subcutaneous. This is a physician-administered procedure, not a self-injection protocol.
