Which should you choose? Here's what you need to know.
Epithalon and SLU-PP-332 are both metabolic / longevity peptides, but they work differently. A synthetic tetrapeptide studied for its potential to activate telomerase and extend telomere length. One of the most discussed longevity peptides. An ERR (Estrogen-Related Receptor) agonist studied as an exercise mimetic. Early research suggests it may replicate some metabolic benefits of exercise.
