Goal-based evidence reviews
12 evidence maps ranked by source depth and regulatory status, not popularity.
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.
4 compounds reviewedBest Compounds for Mitochondrial Research
An evidence review of NAD precursors, MOTS-c, methylene blue, and 5-Amino-1MQ for mitochondrial and metabolic research.
4 compounds reviewedBest 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.
5 compounds reviewedBest 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.
3 compounds reviewedBest 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.
5 compounds reviewedBest 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.
2 compounds reviewedBest 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.
3 compounds reviewedBest 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.
4 compounds reviewedBest Peptides for Skin and Anti-Aging
Source-backed guide to the most researched peptides for skin repair, wrinkle reduction, and anti-aging biology — GHK-Cu, Argireline, Matrixyl, and Epitalon.
2 compounds reviewedBest 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.
3 compounds reviewedBest 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.
3 compounds reviewedBest 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.
