Affiliate disclosure

Last reviewed August 2026

WeighLab is reader-supported, and this page states plainly how that support works. It is written to meet the Federal Trade Commission's expectation that a site disclose its financial relationships clearly and where readers will see them.

Some outbound links earn a commission.

When you follow certain links from WeighLab to a provider and go on to sign up, we may receive a commission. That commission comes from the provider, not from you — the price you pay is the same whether you arrive through one of our links or reach the provider directly. To keep this straightforward, treat any provider link on the site as one that may be commissioned rather than tagging pages individually. This revenue is what funds the research, the ongoing re-checking of provider pricing, and keeping the calculators free to use.

Commissions never move a score or a price. They do decide placement.

Whether or not a provider pays a commission has no bearing on how it is evaluated. The Cost-Efficiency Index is applied to every provider through the same published rubric, a commission adds nothing to that score, and no payment changes the pricing figures shown in a review or a calculator. What a commercial relationship does affect is where a provider is placed in a list — which is a different thing from what it scored, and the next section sets out exactly how that works rather than leaving you to infer it.

Editorial work stays independent of revenue.

The people who research and write WeighLab do so independently of any commercial arrangement. We decide which providers to model and what to say about them based on reader interest and the evidence, not on who pays. We do not accept payment to alter a conclusion, and a provider cannot buy a more favorable review or a better score. Placement is the exception, and we would rather name it plainly: on the value leaderboard and on our annual-cost and molecule rankings alike, providers we have a commercial relationship with are listed first as a block, ahead of those we do not. Within each block, the leaderboard orders on the Cost-Efficiency Index and the annual-cost rankings order strictly on the disclosed price, ascending. Our flagship cheapest-GLP-1 ranking is the one exception and works differently: it is ordered by the Cost-Efficiency Index rather than partitioned, so partners and non-partners sit interleaved there, with a small bounded edge to partners in the sort and no block.

The honest way to read that: a provider at the top of one of these lists is there because it both scored well under the Index and has a commercial relationship with us. Neither fact cancels the other. The score beside every row is the unmodified one, so the fastest way to check us is to read down the numbers rather than the order — and where a list is split, the rows below the split are ordered on exactly the same basis as the rows above it.

The relationships take a few forms.

Most compensation reaches us through affiliate networks that track a referral when a reader signs up with a provider. Alongside those tracked links, a provider may occasionally receive promotional emphasis on the site, such as a featured position or spotlight. Emphasis of that kind is a placement choice and is covered by this same disclosure; it never substitutes for, or influences, the score a provider earns under the Index. Beyond standard affiliate agreements, WeighLab is not owned by, or formally affiliated with, any provider, pharmacy, or drug manufacturer.
