Synthetic GHRH(1-29), the active fragment of growth hormone-releasing hormone
Mild side effects, such as redness at the injection site, are possible, but serious side effects are rare
It's also being investigated alongside other mitochondrial-targeting peptides like SS-31 (elamipretide), which focuses on restoring mitochondrial membrane function, creating a multi-pronged approach to cellular rejuvenation
Who Are the Best Candidates for a Vitamin Shot
As a GLP-1 receptor agonist, semaglutide mimics the actions of endogenous GLP-1 but with one critical engineering advantage: while native GLP-1 has a biological half-life of only a few minutes before being cleaved by the enzyme DPP-4, semaglutide achieves a half-life of approximately seven days through structural modifications that include an Aib amino acid substitution at position 8 (blocking DPP-4 recognition) and a C18 fatty acid chain attached via a linker, which enables reversible binding to albumin in the bloodstream
