How the WeighScore Is Calculated

A grade is only as trustworthy as the formula behind it. So here is ours, in full — the six dimensions, their weights, how they roll up into a single 0–100 WeighScore, and the rules that keep the number honest. If you would rather see it as a reference table, the full methodology lays out every weight side by side.

One formula, every provider The WeighScore is not a vibe. Every provider is scored 0–100 on the same six dimensions, with the same weights, and mapped to the same letter scale. There is no bonus lane for providers we like and no penalty box for ones we do not. Same rubric, same math, every time — that consistency is what makes two grades actually comparable.

The six dimensions and their weights **Cost value — 25%.** The heaviest weight, because price is where providers most often mislead. We score the normalized cost of an equivalent maintenance dose, and how it moves after any introductory period. Hidden step-ups cost points. Our guide to [what compounded GLP-1 costs per month](/what-compounded-glp1-costs-per-month) shows the normalization we run.

**Dose and formulation — 20%.** Breadth of molecules, titration flexibility, and route options. This matters because the molecules are not interchangeable: once-weekly semaglutide 2.4 mg produced a mean −14.9% body-weight change in the STEP-1 trial¹, while tirzepatide reached up to about −20.9% in SURMOUNT-1². A provider that stocks both molecules and a full titration ladder can follow the evidence; one that stocks a single dose cannot. We unpack the trade-off in semaglutide vs. tirzepatide.

**Clinical oversight — 20%.** Prescriber model, provider verification confidence, and how care is supervised and escalated. This is the safety backbone of the score.

**Labs and monitoring — 15%.** Whether baseline labs, ongoing check-ins, and side-effect monitoring are included or sold as extras.

**Fulfillment — 12%.** Pharmacy sourcing transparency, shipping reliability, and cold-chain handling — including whether a provider will tell you which pharmacy fills your prescription.

**Contract terms — 8%.** Cancellation friction, refund posture, auto-renewal honesty, and lock-in. Small weight, real consequences.

How the dimensions become one number Each dimension is scored 0–100 on its own merits. We then multiply each dimension score by its weight and sum the results into a single weighted 0–100 WeighScore. Because the weights total 100%, a provider that is merely average everywhere lands mid-pack, while a standout on cost value moves more than a standout on contract terms — by design, since the weights encode how much each factor matters to a real buyer.

From score to letter grade The WeighScore maps to a letter: A (93+), A− (90–92), B+ (87–89), B (83–86), B− (80–82), C+ (77–79), and C (below 77). A grade is a relative read on today's market — not a safety rating and not medical advice. A high grade means a provider compares well right now, not that it is right for you.

What never moves the number Affiliate relationships. A provider that pays us a commission runs through the exact same rubric as one that does not, and a weak provider is graded low regardless of any partnership. What a commercial relationship can affect is promotional emphasis — a spotlight or a highlighted row — and that is always labeled and never the score itself. The full detail lives in our [disclosure](/disclosure), and the reference weights in the [methodology](/methodology).

Facts change; the formula does not Provider pricing, dosing menus, and terms move constantly, so grades are re-scored as the facts change. The one thing that stays fixed is the formula. That is the point of a scorecard: when the inputs shift, you can trust that only the inputs shifted. See the formula applied across the market in our [reviews](/research) and [comparisons](/compare).
