Peptides
Cardiogen: heart-cell research without a clinical outcome
What is it?
Cardiogen is a short peptide marketed for heart-tissue support. It belongs to the bioregulator category, where proposed tissue targeting is often derived from cell or organ-culture observations. [1,2]
What do studies show?
Researchers exposed myocardium tissue from young and old rats to Cardiogen and reported altered culture development relative to controls. A separate organotypic culture study also reported stimulation of corresponding heart explants. These are laboratory observations, not tests of cardiac output, exercise tolerance, heart failure, or survival in people. [1,2]
Safety
Cardiovascular symptoms such as chest pain, fainting, or shortness of breath need prompt medical assessment. No culture experiment can establish the quality or systemic safety of a research vial, especially in someone with heart disease or cardiac medicines.
DOSE STATUS
How much?
EVIDENCE CONTEXT
Why?
The cited evidence does not establish a dose for this use or product.
One organ-culture paper used 0.05 ng/mL in the culture medium. That is not a human dose and cannot be scaled into an injection. No established effective/safe adult regimen or credible, formulation-matched anecdotal amount was identified. [2]
