Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The market is built upward from dosing volume and realized price rather than assumed as a single total. Treated-patient estimates for the major indications, led by metabolic and cardiovascular disease, are combined with annualized dose regimens and average net realized price per treatment course to produce a unit-based revenue figure for each molecule class and application channel. That bottom-up figure is then checked against the disclosed revenue lines of the largest branded originators and against public shipment and procurement data where it exists. Where the two diverge, the correction is made to the underlying dosing or pricing assumption feeding the bottom-up build, not by averaging the two figures together.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary outreach targets the commercial and procurement roles that actually set price and volume in this market: pharmacy benefit and hospital procurement managers who negotiate net pricing on injectable peptide therapies, specialty pharmacy and distribution executives who see channel volume directly, and regulatory affairs staff who track approval and reimbursement timing for new molecules. Sampling weights toward the United States and the larger European markets, where GLP-1 and related peptide categories carry the most volume, with a smaller allocation to Japan and China to capture manufacturing and generic entry trends. Conversations are structured around confirming or correcting the dosing, pricing and channel-mix assumptions already built into the estimate.

Secondary sources, this report

Desk research draws on FDA and EMA approval and labeling records for named peptide molecules, national drug reimbursement registers including CMS payment and coverage determinations in the United States, and customs and trade classification data filed under the relevant pharmaceutical HS codes for cross-border peptide API shipments. Company filings and investor disclosures from the largest branded originators supply revenue and volume detail for their marketed peptide franchises, and pharmacopeial and manufacturing standards published by USP and the European Pharmacopoeia inform the split between solid-phase, liquid-phase and hybrid synthesis routes. National diabetes and obesity prevalence registers anchor the demand side of the build.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast carries forward the dosing and pricing build rather than trending a historical growth rate. It assumes continued expansion of payer coverage for obesity and metabolic peptide therapies, gradual easing of the manufacturing capacity constraints that limited originator supply through the base year, and a step down in average realized price as the first wave of early peptide analogs loses patent protection later in the forecast window. For the forecast to hold, reimbursement policy in the largest markets needs to keep widening, and originator manufacturing capacity needs to keep pace with prescribing growth without a renewed shortage.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Historical years are back-tested against recorded approval and launch dates for the major peptide molecules already on the market, confirming the modeled uptake curve for each matches its actual prescribing ramp rather than a generic adoption curve. Segment share shifts, particularly the move toward metabolic and cardiovascular indications, were reviewed against national prescribing and reimbursement data before being locked. Sensitivities were run on the price-erosion assumption applied to peptides nearing patent expiry and on the pace of manufacturing capacity additions, since those two assumptions move the forecast more than any other single input.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest in the metabolic disorder and innovative-molecule lines, where dosing, pricing and reimbursement data are documented across multiple public sources. It is thinner in the generic and biosimilar lines, where pricing is less consistently disclosed, and in the smaller regional markets across Latin America and the Middle East and Africa, where prescribing data is reported less frequently. A material revision would follow from an unexpected change in reimbursement policy for weight-management peptide therapies or from an earlier-than-expected wave of patent expiries, either of which would move the price and channel-mix assumptions the whole build depends on.
