Peptide therapy: types, benefits, risks & what to know in 2026
FDA-approved medicines, compounded products, and investigational peptides — the entire landscape, with the evidence graded honestly. Semaglutide vs. BPC-157 vs. everything in between, plus how to verify the pharmacy that dispenses your peptide.
Read the guide →Does glutathione work? What human research shows
Sustained oral dosing can raise measured glutathione levels — that part holds up. Whether that changes anything clinical is a harder question. A careful, condition-by-condition read of the trials.
Read the guide →Glutathione and detox: what it does, what it doesn't
Glutathione is the wellness industry's favorite "detox" molecule. It does participate in the body's detoxification system — but supplementing it hasn't been shown to remove more toxins. Where the biology ends and the marketing starts.
Read the guide →Does lion's mane improve memory? What human studies actually show
Lion's mane is marketed for memory and brain fog. The human evidence is thin, small, and short — the most-cited studies come from animals. A careful look at what has and hasn't been demonstrated in people.
Read the guide →Longevity medicine: separating science from marketing
Rapamycin, metformin, senolytics, NAD+ boosters, cold plunges. What actually extends healthspan on current human evidence — and what's still a well-marketed hypothesis.
Read the guide →GLP-1 medications, explained clearly
Semaglutide, tirzepatide, and the whole class — how they work, who they're for, what to expect, and how to tell a good provider from a bad one.
Read the guide →NMN supplements: what the human evidence actually shows
NMN raises NAD+ levels — that part is confirmed. What that means for aging, energy, and healthspan is a much longer conversation. A careful, trial-by-trial review.
Read the guide →NMN vs NR: which one is actually better?
Two NAD+ precursors, the same biology, very different marketing. The head-to-head trials, the regulatory history, the cost difference, and the honest answer to whether one wins.
Read the guide →How to eat on a GLP-1 (and why most people get it wrong)
If you're starting semaglutide or tirzepatide, what you eat decides whether you'll tolerate the medication and whether the weight you lose actually stays off. Protein targets, meal timing, and the food choices that keep patients on treatment long enough to reach their goals.
Read the guide →Are NAD+ supplements actually worth it?
NMN and NR do raise NAD+ levels in humans — that part is real. Whether the rest of the longevity promise (the energy, the cellular repair, the slowed aging) holds up is a much harder question. Here's what the data actually shows.
Read the guide →Longevity supplements, ranked by what actually works
NMN, Resveratrol, Urolithin A, Spermidine, Fisetin, Lion's Mane, Glutathione. Some are worth the money. Most aren't. A compound-by-compound review weighed against actual human evidence — not preclinical promise.
