*Attia separates signal from noise across the peptide landscape in a full AMA episode.*
Research VialsA research review of GHK-Cu — the copper-binding tripeptide studied for collagen synthesis, wound healing, gene expression modulation, and anti-inflammatory signaling.
PubMed · Cell reports. MedicineJi L et al., Cell reports. Medicine · 2026 Apr 21. PMID 41956096.
Lifespan.ioA new study found that GLP-1 receptor agonists (weight-loss peptides like semaglutide) cause no more muscle loss than plain caloric restriction. That's a meaningful data point for anyone weighing body-composition tradeoffs on GLP-1 therapy.
Lifespan.ioForever Healthy released AI4L, an open-source AI system built to help people navigate practical longevity decisions. It's designed to translate research into actionable guidance — without a prescription pad in the loop.
Lifespan.ioNew data shows creatine amplifies some benefits of power training in older adults beyond what exercise alone delivers. For anyone tracking muscle-preservation strategies, this is worth filing alongside the GLP-1 muscle data above.
BluePrint (Bryan Johnson)Johnson's team reviewed the clinical evidence on skin aging, then built their own formulation around it. The post details which actives earned a spot — and which popular ingredients didn't survive scrutiny.
Dr Trevor BachmeyerBPC-157: The Research, the Censorship, and Why Big Pharma Can’t Compete In this episode I deliver a direct rebuttal to claims made on recent podcasts proving that BPC-157 is safe, highly effective, and being suppressed because it can’t be

Regan ArchibaldIf you’re wondering whether CJC-1295 works best alone or paired with Ipamorelin, this video breaks down the science behind growth hormone pulses, peptide stacking, and why many people may not be getting the full benefits from their protocol
Research VialsWhy third-party testing is the gold standard for research peptides. HPLC methods, mass spec verification, COA interpretation, and how to confirm test authenticity.

Peter AttiaAttia's latest AMA covers NAD+ (a compound linked to mitochondrial function and longevity research), metabolic health, strength training, and dementia risk reduction. A broad but practical readout from one of the field's most rigorous clinician-researchers.
BluePrint (Bryan Johnson)Johnson's team simplified his protocol significantly for 2026. The post walks through what survived the cut and why — a useful lens on how evidence-based optimization iterates over time.
Lifespan.ioResearchers in Aging Cell mapped the link between gut-wall aging and shifts in the microbiome toward harmful bacteria. The findings connect intestinal aging biology to a practical target for intervention.
Lifespan.ioLifespan.io's monthly digest covers the research, clinical, and funding developments that mattered in April 2026. A strong orientation read if you missed anything in the longevity space last month.
Fight Aging!Mouse data shows that the pattern of oxygen drops caused by sleep apnea raises the burden of senescent cells in blood vessels. Senescent cells (damaged cells that stop dividing but don't die) are a known driver of vascular aging.
Lifespan.ioRockefeller University's Dr. Junyue Cao explains how ultra-high-throughput single-cell technologies are revealing the aging process at cellular resolution. His lab's work is laying groundwork for precision intervention targets.
BluePrint (Bryan Johnson)Johnson tested his home for environmental toxins and found problems across air quality, water, and cookware. The post covers 14 specific changes he made — ranging from free behavioral shifts to equipment upgrades.
Research VialsA ranked review of peptides studied for tendon, ligament, muscle, and bone repair — BPC-157, TB-500, GHK-Cu, and growth hormone secretagogues.
BluePrint (Bryan Johnson)Johnson's bone health post anchors the case in mortality data: higher density in older adults linked to 51% lower death risk in women, 23% lower in men. The write-up covers which interventions have real evidence behind them.
Peter AttiaThe first trial combining rapamycin with exercise produced weak results. Attia argues that one negative study doesn't close the book on rapamycin as a longevity drug — but it does raise the bar for future trial design.
Research VialsThe three forms of Epitalon (a peptide studied for telomerase activation and aging) differ in stability, bioavailability, and research context. This guide breaks down what separates them and when each form appears in the literature.
Research VialsA reference map of known interactions between common research peptides — where combinations may reinforce each other, where they compete, and where the evidence is thin. A useful cross-check for any multi-peptide research design.
