Boards

Ranked seller boards

These rank companies, not compounds — on whether what they say about what they sell matches what has actually been tested. Every board prints the rule that put a company on it and the rule that decided the order, because a ranking whose method you cannot read is one you have to take on trust.

Boards

Each one a stated rule, not a curated list.

Companies graded

Every one with its own published review.

Publish a certificate

Of 94 companies. Almost every one says testing happens.

The boards

Peptide sellers, ranked by whether their claims match the trials

Every peptide and GLP-1 seller we have reviewed, ranked by how much of what they say about their products is actually supported by published trials.

Companies on it: 94
Top of the list: Pallas Health

The sellers that tell you which pharmacy actually fills your prescription

A telehealth brand is almost never the pharmacy. These are the companies that name the one compounding or dispensing pharmacy behind their products.

Companies on it: 38
Top of the list: Pallas Health

Semaglutide sellers, and whether what they say matches the trials

Every company we have reviewed that dispenses semaglutide — the approved pen and the compounded copy alike — ranked on whether its words survive the trials.

Companies on it: 74
Top of the list: Sprout Health

Tirzepatide sellers, and whether what they say matches the trials

The companies dispensing tirzepatide, ranked on whether their own description of it survives contact with SURMOUNT and the rest of the published record.

Companies on it: 58
Top of the list: Trimi

Sermorelin sellers, and what the human trials actually show

Sermorelin is sold for sleep, recovery and anti-aging by nearly every clinic here. This board counts how many of those claims a human trial supports.

Companies on it: 39
Top of the list: DirectMeds

NAD+ sellers, and what a human trial has actually tested

Twelve of the fifteen companies reviewed here sell NAD+. This board counts how many of their claims about it a published human trial supports.

Companies on it: 43
Top of the list: Pallas Health

Glutathione injection sellers, and what the trials support

Glutathione is sold here for detox, skin and immune support. This board counts, company by company, how many of those claims a human trial reaches.

Companies on it: 16
Top of the list: Shed

GHK-Cu sellers, and how far the copper peptide evidence goes

GHK-Cu is the one peptide here with real dermatology trials behind it — and the claims attached to it still tend to reach past them. Four sellers, graded.

Companies on it: 12
Top of the list: Eden

PT-141 sellers, and how the claims compare with the trials

Bremelanotide has phase 3 trials and an approved product behind it — in one indication, in one population. This board grades what four sellers do with that.

Companies on it: 17

Peptides sold to women: who sells them, and what the trials say

The companies whose own product pages address women, graded on whether the claim they make to that audience is one the published trials support.

Top of the list: Eden

Peptides sold to men: who sells them, and what the trials say

The companies whose own product pages address men, graded on whether the claim they make to that audience is one the published trials actually support.

Companies on it: 16
Top of the list: Eden

The sellers that will dispense the approved drug, not only a copy

Most companies here sell a compounded copy of a molecule that already exists as an approved drug. These are the ones that will dispense the approved product.

Companies on it: 12
Top of the list: Eden

The sellers that say anything at all about how their product is tested

Almost every peptide seller says its products are tested. This board is the ones that describe the testing — and the count of those publishing a certificate.

Companies on it: 18
Top of the list: Trimi

The sellers that name the states they cannot reach

“Available in most states” tells you nothing. These are the companies that name the specific states where they will not dispense, before you sign up.

Companies on it: 16
Top of the list: Eden

How every one of these is ordered

Printed on every board

Companies we have a paid relationship with are listed first, and we say so here rather than marking individual rows. Within that group and within the rest, the order is the same measured one: how much of what each company sells is described accurately — the share of the products this board counts whose marketing claim matches the trials behind it. Ties go to the company with more matching claims, then to the one that names its pharmacy, then to the one that publishes a testing regime, and last of all to alphabetical order. Being a partner changes where a company sits, never what its numbers say.

The grouping is the only thing a commercial relationship changes, and it is stated rather than marked on individual rows. It moves where a company sits and never what its numbers say: across 379 graded products, every count, rate and disclosure beside a row is computed from that company’s own published claims and is identical whether or not we are paid. Within each group the ranking is the same measured one, so if you would rather ignore the grouping entirely, read the claims column. What we are paid for, and what it does not buy, is on the disclosure page.

Looking for the best peptide, not the best seller?

These boards will not answer that, and it would be easy to pretend otherwise. Which molecule has evidence behind it depends entirely on what you are trying to change, so the answer lives on the goal pages — each one ranks the compounds against a single outcome with the strength of the human evidence printed on every row.
