Angiotensin-(1-7) vs TB-500
An educational, source-based comparison of Angiotensin-(1-7) and TB-500 — how each peptide works, what it's researched for, and what to know before going deeper.
Counter-regulatory peptide of the renin-angiotensin system.
A heptapeptide of the renin-angiotensin system that acts on Mas receptors. Research demonstrates counter-regulatory effects to angiotensin II, promoting vasodilation, anti-inflammatory signaling, and anti-fibrotic effects in cardiovascular and renal tissues.
- Pulmonary hypertension and fibrosis
- Heart failure with preserved ejection fraction
- Acute lung injury and ARDS
- Diabetic nephropathy
- • Investigational; not FDA-approved.
- • Interaction with ACE inhibitors and ARBs requires careful study design.
Synthetic fragment of Thymosin Beta-4 studied for tissue and vascular repair.
A synthetic peptide fragment of Thymosin Beta-4 (Tβ4). Research suggests it upregulates actin, promotes cell migration, angiogenesis, and modulates inflammation — supporting repair in muscle, tendon, cardiac, and corneal tissue models.
- Muscle and tendon repair
- Cardiac tissue recovery (preclinical)
- Corneal and dermal wound healing
- Hair follicle stem cell activation
- • Not FDA-approved; banned by WADA.
- • Most evidence is preclinical.
Angiotensin-(1-7) vs TB-500 — Key differences
- Class: Angiotensin-(1-7) is classified as Cardiovascular · Anti-inflammatory, while TB-500 is Tissue Repair · Vascular.
- Primary research focus: Angiotensin-(1-7) — pulmonary hypertension and fibrosis; TB-500 — muscle and tendon repair.
- Tag: Cardiovascular · Anti-inflammatory vs Recovery.
