Methodology

How we rate evidence, describe regulatory status and calculate prices, so you can judge our pages for yourself.

The evidence scale

Each compound gets one rating from 1 to 5. It describes the quality of the published literature on the molecule, not how promising or popular it is, and it does not depend on whether Nordapep sells it.

  • 5/5 · Approved drug, phase 3 trials. The molecule is an approved medicine somewhere, backed by randomised phase 3 trials. Currently: Semaglutide, Tirzepatide, PT-141, Liraglutide, Tesamorelin, Afamelanotide, Setmelanotide, Oxytocin, Exenatide, Pramlintide, Teriparatide.
  • 4/5 · Late-stage human trials. Published randomised human trials (typically phase 2) and/or an active phase 3 programme, but no approval yet. Currently: Retatrutide, Cagrilintide, Thymosin alpha-1, SS-31, Survodutide, Mazdutide.
  • 3/5 · Early human trials. Early-phase human studies with meaningful sample sizes. Currently: LL-37, Kisspeptin-10, Sermorelin, GHRP-2, Gonadorelin, ARA 290.
  • 2/5 · Mostly animal and in vitro. Mainly animal and cell work, possibly with small or uncontrolled human reports. Currently: BPC-157, GHK-Cu, Semax, Selank, Melanotan II, CJC-1295, Ipamorelin, GHRP-6, MOTS-c, Hexarelin, AOD-9604, Humanin.
  • 1/5 · Limited, preclinical or single-group. Preclinical only, or a literature concentrated in one research group with little independent replication. Currently: TB-500, Epithalon, IGF-1 LR3, DSIP, KPV.

Regulatory status

We state whether the MHRA (UK), EMA (EU) and FDA (US) have approved the molecule, and note regional registrations elsewhere. Status lines are re-checked at every review.

A high rating for an approved medicine refers to that medicine. It is not evidence for research-grade material, which is not a medicine and has not been evaluated by any regulator.

Prices and price per mg

Prices come from Nordapep's live catalogue and refresh hourly. Price per mg is the listed price divided by the stated milligrams for that size. If a live price cannot be fetched, we show an indicative price and say so. Prices exclude shipping.

What we will never publish

  • Dosing protocols or any guidance for human or animal use.
  • Claims about outcomes in people.
  • Sponsored rankings. The evidence order is set by the rubric.
