About the Author
Meet Mike
Hey, I'm Mike — a passionate researcher and health enthusiast who's spent years diving deep into the science of peptides.
I started Mike's Pep Talk because I couldn't find a single place that combined real research, honest pricing comparisons, and plain-English explanations. This site is my attempt to fix that.
Whether you're a biohacker, an athlete, or just curious about what these compounds actually do — you're in the right place. I cover the research, the mechanisms, the legal landscape, and everything in between.
My mission: Cut through the noise and give you clear, credible, research-backed information you can actually use.

Delta-Sleep-Inducing Peptide
DSIP, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
Delta-Sleep-Inducing Peptide (DSIP) is a neuropeptide originally isolated from the cerebral venous blood of rabbits in state of induced sleep. It is widely studied for its potential to modulate sleep patterns, stress response, and endocrine regulation.
CJ-1295 DAC
CJC-1295 with Drug Affinity Complex, Modified GRF(1-29) DAC
CJC-1295 DAC is a synthetic analog of Growth Hormone-Releasing Hormone (GHRH) modified with a drug affinity complex to increase its half-life significantly. It is used in research to study prolonged stimulation of growth hormone secretion.
Humanin
HN, Mitochondrial-derived peptide
Humanin is a 24-amino acid mitochondrial-derived peptide that plays a critical role in cellular protection and metabolic regulation. It is recognized for its potent cytoprotective properties, particularly against apoptotic stimuli in various tissues.
SS-31
Elamipretide, MTP-131
SS-31 is a novel mitochondrial-targeted peptide designed to stabilize cardiolipin in the inner mitochondrial membrane. It is primarily researched for its potential to improve mitochondrial function and mitigate oxidative stress in various tissues.
Melanotan II
MT-II, Melanotan 2
Melanotan II is a cyclic heptapeptide analogue of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH). It is primarily studied for its ability to induce skin pigmentation and its potential effects on sexual function and appetite regulation.
Tesamorelin
TH9507, Egrifta
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to secrete endogenous growth hormone. It is primarily researched for its potential to reduce visceral adipose tissue and improve metabolic parameters.
