Dr. Amr Nassar is a general surgeon and a clinical reviewer on Biohack Blueprint's medical advisory board. His clinical practice and published research cover the specialties he signs off on the site: the pathways by which longevity supplements interact with glucose regulation and insulin signalling, the gut and gastrointestinal side of metabolic supplementation, the evidence for and against supplemental interventions on sarcopenia and bone density, and the senolytic literature and its limitations. His involvement here is editorial only.
His published work includes High Amylase Level in Drain Fluid as an Early Predictive Biomarker for GIT Anastomotic Leakage (ResearchGate) — a clinical study identifying an early biomarker that lets surgeons detect gastrointestinal anastomotic leakage before it becomes clinically obvious. That habit of asking "what is the earliest honest signal here" is the same discipline he brings to reading longevity trials.
On product reviews, his job on the byline is to sign off on the mechanism and the evidence framing in the cardiometabolic, gastrointestinal, musculoskeletal, and senescence sections — including flagging the dose-mismatch pattern that has become Biohack Blueprint's most consistent editorial finding across spermidine, fisetin, creatine, and Ca-AKG. Where a manufacturer's recommended dose does not match the dose used in the trial that produced the outcome, that is stated on the page. The commercial framing of the review — the DoNotAge affiliate relationship, the BB10 code, the buy-through recommendation — is Biohack Blueprint's editorial decision, not his.
Independence. Dr. Nassar has no commercial relationship with DoNotAge. He is not paid by the manufacturer, holds no equity in the company, and receives no product, discount, or consideration in exchange for his clinical review. He contributes his review time to Biohack Blueprint pro bono and receives no compensation from Biohack Blueprint or DoNotAge for the review work itself. If his read of the evidence is that a claim does not hold up, that is what appears on the page.
