How we fund the site

We earn commissions from affiliate partnerships with some — but not all — vendors on this site. Where an affiliate relationship exists, outbound links carry rel="sponsored" and a visible disclosure appears on every page that contains the link. We do not accept payment for inclusion in rankings, and we do not alter ranking order in exchange for higher commission rates.

As of April 2026, we have affiliate partnerships with two vendors: Particle Peptides (15% first / 10% recurring, 365-day cookie) and SwissChems (20% per sale). Every other vendor ranked on this site earns no commission when readers purchase through our links — inclusion is purely editorial.

Our editorial standards

• Facts are dated. Pricing, testing parameters, affiliate commissions, and regulatory status carry an as of date. Facts older than 90 days trigger a refresh review. Regulations older than 180 days are re-verified against official sources.
• Research-use-only framing is load-bearing. No content implies human therapeutic use. No content suggests dosages for humans. This is both a legal requirement under Directive 2001/83/EC and — more importantly — a reflection of how peptides should actually be discussed in a research context.
• We reject vendors. Baltic BioLabs is covered because readers ask about it — but the review carries an explicit warning flag and a "not recommended" verdict. Editorial judgment means saying no, not just yes.
• Corrections are timestamped. When we get something wrong, we note the correction inline with a date. Silent edits undermine trust; visible edits build it.

Conflict-of-interest disclosure

Kulik Media UG and its employees do not hold equity in any peptide vendor reviewed on this site. We do not offer paid placement, paid reviews, or paid ranking positions. Where an affiliate relationship changes our exposure — e.g., if a new vendor launches a partnership — this page is updated within 30 days.

How we score vendors

Full details live on our methodology page. In short: each vendor is scored across five weighted dimensions — testing depth, stated purity, EU-friendliness (warehouse, shipping, customs risk), price-to-value, and trust signal — then a narrative editorial layer adjusts for factors the score can't capture (e.g., the Peptide Sciences shutdown, the Baltic BioLabs GDPR incident).
