Thymosin Alpha-1 vs BNP (B-type Natriuretic Peptide)

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Thymosin Alpha-1

Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.

BNP (B-type Natriuretic Peptide)

BNP is a cardiac neurohormone released primarily by ventricles in response to volume/pressure overload. It's a major biomarker for heart failure and has therapeutic applications as nesiritide.

Side-by-Side Comparison

AspectThymosin Alpha-1BNP (B-type Natriuretic Peptide)
MechanismEnhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes.Similar to ANP - activates NPR-A receptors to produce vasodilation, natriuresis, and RAAS suppression. Released in response to ventricular wall stress.
Typical DosageClinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary.Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure.
AdministrationSubcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols.Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically.
Side EffectsGenerally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue.Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients.
