Nutrition & Supplements
Supplements, peptides, diets and foods checked against the research: what the human trials found, the doses they used and the risks they saw. Plain-English verdicts with every source linked.
-

Copper peptides (GHK-Cu) deliver modest, real skin gains in creams, but injectable GHK-Cu has zero human efficacy trials. Here’s what the evidence shows.
-

Growth hormone peptides reliably raise IGF-1, but only tesamorelin proves a real benefit. Here’s what the science shows on muscle, aging, and cancer risk.
-

The cholesterol paradox is real: those with the lowest cholesterol die soonest. But frailty, not protection, explains it, and LDL still causes heart disease.
-

Collagen peptides are the rare supplement with real human trials, but the skin benefit is modest and the joint evidence is stronger. Here’s the honest read.
-

Paper straws can carry toxic substances: forever chemicals were in 90% of brands tested, and a suspected carcinogen leaked into hot soda. Harm is unproven.
-

BPC-157 has 31 years of rat data and not one completed human trial. Inside the healing peptide’s real evidence, the missing pharmacology, and the first RCT.
-

Research peptides are sold as “not for human use”: a legal fiction. Inside the thin human evidence, the arsenic found in vials, and where the law stands now.
-

A 2023 mouse study crowned taurine a longevity star; a 2025 correction reset the story. Here’s what the human evidence on taurine and aging honestly shows.
-

Senolytics work in mice. In people, dasatinib and quercetin missed the main goal of a bone trial but improved liver scarring in a small 2026 trial.

Low-dose rapamycin extended lifespan in mice and passed its first human safety trial. The honest science on rapamycin for longevity: hype versus real hope.
