B7-33 vs TB-500
| Attribute | B7-33 Single-chain relaxin analog | TB-500 Thymosin Beta-4 fragment |
|---|---|---|
| Category | Heart & Cardiovascular Health | Healing & Recovery |
| Best known for | Anti-fibrotic and cardiovascular research | Systemic tissue repair and recovery research |
| In plain English | It mimics relaxin's anti-scarring effects without the full hormone's downsides. | If BPC-157 is the 'localized fixer,' TB-500 is the 'systemic upgrade.' Researchers study it for whole-body recovery effects, especially around cell migration and new blood vessel formation. |
| How it works | Selectively activates the RXFP1 receptor's anti-fibrotic signaling pathway while avoiding cAMP-mediated effects. | TB-500 binds actin and promotes cell migration to injury sites. It's been studied for upregulating wound healing factors and modulating inflammatory responses. |
| Researchers study | Cardiac fibrosis, pulmonary fibrosis, and tissue-remodeling models. | Wound healing, cardiac tissue repair, hair follicle research, and post-injury recovery in animal models. |
| Internet discussion | Niche; discussed in anti-aging and cardiovascular research circles. | Forum users describe TB-500 as the 'whole-body' counterpart to BPC-157. Anecdotes around acute injuries, post-surgery recovery, and even hair regrowth. |
B7-33
Anti-fibrotic and cardiovascular research
It mimics relaxin's anti-scarring effects without the full hormone's downsides.
Selectively activates the RXFP1 receptor's anti-fibrotic signaling pathway while avoiding cAMP-mediated effects.
Cardiac fibrosis, pulmonary fibrosis, and tissue-remodeling models.
Niche; discussed in anti-aging and cardiovascular research circles.
B7-33 is a single-chain relaxin analog researched for anti-fibrotic and cardiovascular protection.
TB-500
Systemic tissue repair and recovery research
If BPC-157 is the 'localized fixer,' TB-500 is the 'systemic upgrade.' Researchers study it for whole-body recovery effects, especially around cell migration and new blood vessel formation.
TB-500 binds actin and promotes cell migration to injury sites. It's been studied for upregulating wound healing factors and modulating inflammatory responses.
Wound healing, cardiac tissue repair, hair follicle research, and post-injury recovery in animal models.
Forum users describe TB-500 as the 'whole-body' counterpart to BPC-157. Anecdotes around acute injuries, post-surgery recovery, and even hair regrowth.
TB-500 is a systemic recovery research peptide studied for actin regulation, cell migration, and whole-body wound healing.
