Dr. Valter Longo 5-Day Fasting Mimicking Diet (FMD)

Diet & Nutrition
Impact: 9.6/10
Grade A (Human RCT)

Depletion of circulating white blood cells during 5 days of nutrient deprivation followed by refeeding activates PKA-dependent self-renewal of hematopoietic stem cells.

PubMed Citation:PMID: 28202779

72-Hour Prolonged Autophagy Fast

Fasting Protocols
Impact: 9.6/10
Grade A (Human RCT)

A 72-hour fast forces the degradation of damaged leukocytes, which upon refeeding triggers multi-lineage hematopoietic stem cell self-renewal.

PubMed Citation:PMID: 24905167

Progressive Resistance Training

Musculoskeletal & Structural
Impact: 9.5/10
Grade A (Human RCT)

High mechanical strain activates quiescent satellite stem cells via Notch and Wnt signaling, driving de novo myofiber repair.

PubMed Citation:PMID: 24561114

DEXA Whole-Body Composition Scan

Diagnostics & Tracking
Impact: 9.3/10
Grade A (Human RCT)

Measures appendicular lean mass index (ALMI) and site-specific cortical/trabecular bone mineral density (BMD), detecting occult sarcopenia and osteopenia driven by satellite stem cell decline and osteoprogenitor exhaustion.

PubMed Citation:PMID: 23746684

Post-FMD High-Leucine Refeed & Stem Cell Renewal

Cellular Regeneration
Impact: 9/10
Grade A (Human RCT)

Clears damaged, pre-senescent progenitor pools during the fast and stimulates fresh stem cell division and lineage differentiation during the refeed.

PubMed Citation:PMID: 24905161

CJC-1295 / Ipamorelin (GHRH / GHS Secretagogue)

Peptides & Regenerative Biologicals
Impact: 8.9/10
Grade A (Human RCT)

Elevated physiological IGF-1 signaling recruits quiescent muscle satellite stem cells to repair microtrauma, promoting myofibrillar protein accretion and counteracting age-related dynapenia.

PubMed Citation:PMID: 10423235

Enclomiphene Citrate (SERM)

Longevity Therapeutics
Impact: 8.8/10
Grade A (Human RCT)

Preserves testicular spermatogonial stem cell pools and Sertoli cell gametogenesis while stimulating Leydig cell steroidogenesis, avoiding the testicular atrophy seen with exogenous TRT.

PubMed Citation:PMID: 25055002

Tongkat Ali (Eurycoma Longifolia Extract)

Supplements
Impact: 8.6/10
