How to choose a white-label peptide supplier in Europe
What to look at when choosing a white-label peptide supplier in Europe: EU stock, per-batch CoA, price transparency, minimums and truly unbranded vials.
1. Do they hold stock already in the EU?
This is the decisive factor. A supplier with product inside the European Union gives you intra-community shipping (3-5 days) with no customs and no manufacturing waits. If stock is in Asia, you take on lead times and import risk.
2. Independent per-batch CoA?
Require a Certificate of Analysis (HPLC + heavy metals) for every batch, verifiable by batch number. It is what you can show your customers as proof of quality.
3. Public, transparent pricing?
Be wary of suppliers who only quote privately. Public per-vial pricing lets you calculate margins from day one.
4. Reasonable minimums?
A good partner lets you start small (a 4-vial pack per reference) and scale. High minimums force you to tie up capital before validating demand.
5. Truly unbranded vials?
If you plan to sell under your own label, the vials should carry no supplier brand. Then you apply your label and nothing on the vial competes with it. At Peptworks the vials are unbranded (white-label); we don't label or box them with your brand.
