Best Compounds for Longevity Research
An evidence-ranked review of rapamycin, metformin, spermidine, Epitalon, and MOTS-c in longevity research, separating approved drugs and human studies from preclinical peptide claims.
Best For
Best peptides for specific goals
Evidence reviews of peptides discussed in specific health and performance contexts: injury repair, recovery, cognitive enhancement, and more. These are evidence reviews, not recommendations.
Best Compounds for Mitochondrial Research
An evidence review of NAD precursors, MOTS-c, methylene blue, and 5-Amino-1MQ for mitochondrial and metabolic research.
Best Peptides for Cognitive Enhancement
An evidence review of peptides discussed for cognitive enhancement: Cerebrolysin, Noopept, Semax, and Dihexa: ranked by depth of clinical evidence and regulatory status. Cerebrolysin and Semax are Russian pharmaceuticals with some clinical data, Noopept has published Russian human trials, and Dihexa remains preclinical-only.
Best Peptides for Growth Hormone Release
What the public source record shows about peptides studied for growth hormone release: tesamorelin, sermorelin, MK-677, CJC-1295, and ipamorelin ranked by evidence depth and regulatory status.
Best Peptides for Immune Support
What the public source record shows about peptides studied for immune support: Thymosin Alpha-1, LL-37, and KPV ranked by depth of clinical evidence and regulatory status.
Best Peptides for Inflammation Research
An evidence review of Thymosin Alpha-1, LL-37, KPV, BPC-157, and TB-500 for inflammation and immune-signaling research.
Best Peptides for Injury Repair
An evidence review of peptides discussed in injury repair and tissue healing contexts: including BPC-157 and TB-500: with evidence levels, regulatory status, and internal links to compound pages. This is an evidence review, not a recommendation.
Best Peptides for Muscle Recovery
An evidence review of peptides discussed in muscle recovery contexts: including BPC-157, TB-500, and related compounds: with evidence levels, regulatory status, and internal links to compound pages. This is an evidence review, not a recommendation.
Best Peptides for Skin and Anti-Aging
Source-backed comparison of four widely discussed compounds in skin, wrinkle, and anti-aging contexts: GHK-Cu, Argireline, Matrixyl, and Epitalon.
Best Peptides for Sleep
What the public source record shows about peptides discussed for sleep: DSIP and Epitalon reviewed by evidence depth and regulatory status. Both are investigational research peptides with limited human clinical evidence and no FDA approval for sleep indications.
Best Peptides for Stress and Anxiety Research
An evidence review of Selank, Semax, and DSIP for stress, anxiety, and sleep research, emphasizing the limits of Russian clinical literature and older small studies.
Best Peptides for Weight Loss
What the public source record shows about peptides studied for weight loss: retatrutide, tirzepatide, and semaglutide ranked by evidence depth and regulatory status.
