A Real Doctor Reviews 10 Science-Backed Peptides

Oct 7, 2025
In this video, I’m breaking down 10 more fascinating peptides (ok really 9 plus a bonus nonpeptide) that are reshaping the future of medicine, metabolism, and performance.

We’ll cover:
0️⃣ Sermorelin – the OG growth-hormone peptide
1️⃣ Hexarelin – GH secretagogue with potential heart-protective effects
2️⃣ Follistatin 344 / 315 – blocks myostatin for muscle growth
3️⃣ Tesofensine – neurochemical weight-loss compound
4️⃣ Cagrilintide – the next-gen amylin analog for fullness and fat loss
5️⃣ 5-Amino-1MQ – NNMT inhibitor that may shrink fat cells and boost NAD⁺
6️⃣ SS-31 (Elamipretide) – mitochondrial repair and ATP-boosting peptide
7️⃣ FOXO4-DRI – longevity research peptide that clears senescent cells
8️⃣ Dihexa – nootropic peptide for focus and brain connectivity
9️⃣ DSIP – delta-sleep–inducing peptide for stress and recovery

If you’re curious about longevity, peptides, fat loss, mitochondrial health, and performance optimization, this one’s for you.
