The 5 main categories of sources in France
Here is an honest overview of the types of sources available from France, each with its real strengths and limitations.
| Source | Batch COA | Delivery to France | RUO Framework | Support |
|---|---|---|---|---|
| General marketplaces | Almost never | Fast if available | Rarely displayed | Generic |
| Resellers without a COA | None, or "in-house" | Variable | Displayed but unverifiable | Almost nonexistent |
| Non-EU suppliers | Inconsistent | 10-20 days, customs risk | Yes | Time zone, language |
| Specialized foreign sellers | Often third-party | 5-10 days | Yes | Mostly English-speaking |
| BioPep (FR supplier) | Systematic Janoshik COA | 72h France · 5 business days Europe | RUO on every listing | French, Telegram |
How to read the table: general marketplaces regularly delist these molecules and almost never offer a COA. Resellers without a COA sometimes show a lower price, but with no proof of purity whatsoever — that's the real risk. Non-EU suppliers may look attractive on price, at the cost of long delays and a risk of customs holds.
The criterion that really matters: the COA
If there's only one criterion to remember, it's the batch certificate of analysis (COA, Certificate of Analysis). This is the document that separates a serious supplier from an opportunistic reseller.
| COA element | What it proves |
|---|---|
| Purity (HPLC) | Proportion of active molecule vs. impurities, measured by liquid chromatography |
| Identity (LC-MS) | Confirms that the content truly matches the stated peptide |
| Batch number | Links the certificate to the exact vial received |
| Issuing laboratory | An "in-house" COA with no independent third-party lab has no probative value |
At BioPep, every order comes with a COA from Janoshik Analytical, a specialized independent laboratory, linked to the batch number of the vial received — viewable on every product page in the catalog.
Delivery and customs from France
A cheaper source that gets held up in customs or delivered in three weeks ultimately costs more in time and uncertainty than a slightly more expensive but reliable source.
| Aspect | Intra-EU source | Non-EU source |
|---|---|---|
| Delivery time to France | 72h typically | 10 to 20 days |
| Customs fees | None | Possible, risk of seizure |
| Packaging | Neutral in general | Variable |
| Tracking | Number provided at shipment | Often partial |
BioPep ships from France: 72h to mainland France, 5 business days to Belgium, Luxembourg, Germany, Italy, Spain, Portugal, the Netherlands and Switzerland — no customs fees, neutral packaging with no indication of contents.

Regulatory framework: research only
- Research peptides are not medicines — they do not appear on the list of prescription-controlled substances
- They are intended exclusively for laboratory research, never presented as products for therapeutic use
- A reliable supplier clearly displays the Research Use Only (RUO) label on every product

Frequently asked questions
Can you buy research peptides on Amazon or eBay?
Not reliably. General marketplaces regularly delist these molecules and almost never provide a COA from an independent laboratory.
How do you recognize a reliable supplier?
The decisive criterion is a batch COA from an independent laboratory (HPLC purity, LC-MS identity, batch number), backed by shipping from the EU, neutral packaging and a clearly displayed price.
What are the delivery times in France?
With a supplier based in France or the EU, expect 48h to 96h depending on the destination. A non-EU source typically takes 10 to 20 days, with a risk of customs holds.
What payment methods does BioPep accept?
Credit card, Apple Pay and Google Pay, with SSL-encrypted payment.
