research information · not medical advice

Grades rate the published evidence and safety record, not whether a compound will work for you. Several compounds here are controlled substances or banned in sport; most are not approved for use in people.

how the grades work

evidence grades and the ladder

approved, strong human outcome data
phase 2–3 human trials, not yet approved
small or early human studies
animal or cell studies only
contradicted, unsafe, or identity problems
blend grade
a blend is graded on its ingredients, not on studies of the mix: it takes the weakest ingredient’s grade, and its ladder shows how far its least-studied ingredient got

The bars are the evidence ladder: cell studies, animal studies, small human studies, phase 2 trial, phase 3 trial, approved somewhere. Every study, trial and source link in a record is checked against PubMed, ClinicalTrials.gov, PubChem and Wikipedia; doses come only from labels and human trials. No vendor can pay for a grade. the full database with prices

short answers

tier list questions

How is this tier list ranked?
By the evidence grade first: A, approved, strong human outcome data (81); B, phase 2–3 human trials, not yet approved (51); C, small or early human studies (142); D, animal or cell studies only (139); F, contradicted, unsafe, or identity problems (78). Within a grade, compounds rank by how far research got (cell studies up to approval), then by US status, then by name.
Can a vendor or sponsor change a grade?
No. Grades come only from published studies, drug labels and trial registries. Every study, trial and source link in a record is checked against PubMed, ClinicalTrials.gov, PubChem and Wikipedia; anything that does not match is removed.
Why are trenbolone, DNP and most SARMs graded F?
F means contradicted, unsafe or of unclear identity. Trenbolone is a veterinary drug never approved or trialled in people; DNP has caused deaths; several SARMs and oral steroids have case series of drug-induced liver injury. An F is a safety grade, not a ranking of effect size.
Where do the doses come from?
Only from FDA labels, approved labels outside the US and registered or published human trials, each with its source. Animal doses are labelled as animal doses and never converted. There are no forum or vendor doses.
What kinds of compounds are included?
peptides, bioregulators, SARMs, anabolic steroids, steroid & thyroid hormones, small molecules, proteins & hormones, vitamins & nutrients, blends. Blends carry a blend grade: they are graded on their ingredients, not on studies of the mix, and take the weakest ingredient’s grade.
Is this medical advice?
No. PeptideTech is an independent information service. Most research-market compounds are not approved for use in people, and several are controlled substances.
