American suppliers, now also on PeptideCompare
From now on, we're also including a number of carefully vetted American suppliers alongside our existing EU suppliers — some with their own EU warehouse, others shipping directly from the US. What that means for you as a researcher, how we vet them, and why this only strengthens the comparison.
- We now include carefully vetted American suppliers alongside our EU suppliers.
- For orders under €150, a flat €3 customs duty applies since July 2026 — otherwise, little changes.
- The same verification standard applies to everyone: a valid COA, clear labeling, careful shipping.
- More choice, more competition and a different manufacturing origin — without taking marketing claims like “USA made” at face value.
American suppliers on PeptideCompare
From now on, we're also including a number of carefully vetted American suppliers in the database, alongside our existing EU suppliers. Some of them have their own warehouse in the EU and simply ship locally; others ship directly from the US.
Either way, the same independent verification applies as for every other supplier on the site — where a supplier is based doesn't change how critically we look at them.
Does anything change about ordering?
For parcels from the US, a small amount of import duty is added. Since the customs rules changed in July 2026, a flat rate of €3 per parcel applies to shipments under €150. For most orders on this site, that's the only practical difference.
Beyond that, ordering from an American supplier works just like ordering from a European one: you order through their own site, and the supplier handles shipping and customs themselves.
How do we vet American suppliers?
The same standard as always, regardless of where a supplier is based:
- A valid COA per product, no older than 12 months.
- Clear labeling: for laboratory research only, not for human consumption.
- Careful packaging for the longer trip across the Atlantic, with a reshipment guarantee if something goes wrong along the way.
- Verification of the company itself, and — where possible — the same contact and trust-building we pursue with every supplier, not just paperwork.
What does this mean for you?
- More choice. Some compounds and formulations are available from American suppliers earlier, or exclusively, before they're widely available from EU suppliers.
- More competition, sharper prices. More suppliers side by side on one page means a fairer price comparison — exactly what this site exists for.
- Less dependence on one region. If an EU supplier is temporarily out of stock or stops trading, you now have alternatives on the other side of the ocean too.
- A different manufacturing origin. Some of these suppliers manufacture in the US themselves, rather than sourcing from the same manufacturers as many EU suppliers — more diversity in supply chains, and more basis for comparison.
What does “USA made” actually mean?
Some American suppliers market themselves as “USA made” — synthesized in their own lab, rather than sourced and repackaged from peptides already made elsewhere (often China). What they typically claim: production under cGMP-like guidelines, full documentation of every synthesis step, and shorter lead times because there's no international supply chain in between.
Worth noting: those are claims made by the suppliers themselves, not independently verified facts — just like any other claim on a supplier's website. So we don't simply take “USA made” as a quality mark; as always, we look at the COA, the contact, and the actual experience, not the label on the package. It is an interesting data point for researchers specifically looking for a different supply chain than the usual one.
Some context: how big is the peptide industry, actually?
Globally, the broader pharmaceutical peptide market was worth about $140.9 billion in 2025, with North America accounting for nearly 62% of that — the US is by far the largest player here. Europe is a solid second market, but the fastest growth right now is in Asia-Pacific.
Note: this is about the broader, approved pharmaceutical peptide market — think GLP-1 medication, insulin — not specifically the research-peptide market we operate in. No official market data exists for that, since it's an unregulated niche. These figures mainly show how large and mature the underlying American industry is.
This article is about adding American suppliers to the database — not about any specific supplier or product. PeptideCompare shows comparison data for research-use-only, contains no affiliate links and no paid placement, and gives no dosing, administration or medical advice.
