Built like a library, not a blog

See what was measured in people.

The world's largest consumer peptide reference. See what was studied in people, what it costs, and what else supports longevity: peptides, fasting, diet, bloodwork, supplements, and telehealth. Built from 453 compounds and 1,043 human studies, with gaps called out when the human evidence is missing.

What it costs, and who stands behind the vial. Before you buy, and before you ask a clinic.

New: what shrank plaque on a scan

What Reduces Arterial Plaque: Nattokinase, K2, D3, Berberine and the Surprises

What shrank arterial plaque on a scan: nattokinase at 10,800 FU a day in 1,062 people, vitamin K2 and D3 trials from 2026, berberine, aged garlic, EPA, interval training, the Mediterranean diet, intensive lifestyle change and cocoa flavanols. Doses, numbers, bleeding risks, every study linked.

Read what the studies found
  • Carotid plaque size fell 36.0 percent on 10,800 FU of nattokinase a day for 12 months, in 683 people with plaque
  • In the same study, plaque size moved 3.5 percent at 3,600 FU a day: the dose decided it
  • A records review with no placebo group; the tablet maker employed five of the authors

New study, read carefully

Vitamin C and DMSO for Skin Cancer: What the Studies Found

The viral vitamin C and DMSO skin cancer result, checked against the papers: the 2025 squamous cell preprint, the 2022 basal cell trial against imiquimod, a 2026 review, who ran them, and what none of them show.

Read what the studies found
  • 15 of 27 lesions cleared on biopsy, in a 2025 preprint not yet peer reviewed
  • 13 of 15 against 8 of 14 with imiquimod, in the 2022 randomised trial
  • One research group, its own company as sponsor, no independent repeat yet

What did you come here to settle?

These are the searches people really type. Each door opens what was measured for that goal, including what nobody has tested yet.

Before you buy or stack anything, see what was measured in people, what it costs, and where the evidence still runs out.

Weight loss

tirzepatide, semaglutide, retatrutide

The most searched topic. Weight-loss shots tested in large groups of people, kept apart from research chemicals sold right next to them.

Recovery

BPC-157, TB-500, Wolverine stack

Where the marketing is loudest. The human tendon gap is printed, not smoothed over.

Longevity

GHK-Cu, MOTS-c, NAD+

Anti-aging claims, with the real studies in people named. We also name the decades-long study nobody has run.

Sleep and cognition

sleep peptides, memory

Claimed all the time, tested rarely. A study in sick people is not a study in you.

Skin

GHK-Cu, GLOW

Small, short studies, often paid for by the seller. Creams and shots are kept apart.

Safety and legal

are peptides safe, legal, steroids

The trust questions. Whether it is legal, country by country, and whether a peptide is even a steroid (it is not).

Three steps. Then you decide.

Pick a goal. Check the evidence and the price. Then ask a question. This is for learning only. Medical choices still belong with a doctor.

Or start from a blood panel. That is door 1 if you are not sure where to begin. Published pages only. Not a diagnosis.

Pick your goal

Weight loss, recovery, longevity, sleep, skin, or just the safety and legal questions. You do not need the brand name first.

02

Read the human evidence and the price

Studies in people first, with numbers. Animal work never shares the paragraph. Then the price per milligram and the lab test paper behind the seller.

An on-site coach that answers from this archive. It is for learning only. When you want a licensed path, the short list of doctor-backed partners is next. Coach, not doctor.

Ask the coach

The problem you actually have

You should not have to guess who to believe.

Peptide claims clash. Prices are hidden. Lab test papers are weak or missing. Pages about weight-loss shots like GLP-1s mix approved drugs with research chemicals.

The quieter problem is the one that keeps you stuck: you do not know who to believe.

You deserve to see what happened when people were tested, including the studies that found nothing. Here those are shown as numbers, not hidden.

Skip the record and you pay for it. Money goes on untested vials, and the choice gets made from ads instead of from a study.

Your guide

A specialist who built the archive. You remain the one who decides.

Aaron Cuha is a peptide specialist finishing his ICF PCC, with multiple certifications, and more than 20,000 coaching hours. He built this open archive so you can check the measured record yourself. Guide, not guru. Coach, not doctor.

One of the better documented peptide teachers online, because the site is the proof: the counts, the studies that found nothing, and sources you can open.

Built on the same operating system as VITAL OS.

Where to buy is the wrong first question

How much do peptides cost, and who tested the vial? A cheap vial that holds the wrong thing is not a bargain. Check the lab certificate first. Price comes second.
