Sourcing & Commercial Policy

PepGuide is a research encyclopedia, not a storefront. Some peptide profiles may show optional live availability from Rylume. PepGuide and Rylume share an operating team, and that relationship is disclosed wherever the commercial component appears.

What the availability card means

An availability card means the matching Rylume catalog item was reported as in stock by the latest valid catalog feed. It may also display strengths, a recent testing date, and a link to batch records when those fields are available.

The source availability directory brings those standardized listings together without adding prices, promotions, or vendor claims to the research articles.

It does not mean:

• the product is approved for personal or clinical use;
• a listed strength or protocol is appropriate for a particular person;
• availability influenced the PepGuide article, ranking, safety language, or conclusions; or
• a batch record replaces independent review of identity, purity, handling, and jurisdiction.

Editorial and commercial separation

The integration is deliberately narrow:

• Research claims are supported by scientific and regulatory sources, never by vendor copy.
• Prices, discounts, promotional claims, and urgency language are excluded from PepGuide profiles.
• A product being available does not determine whether a peptide receives coverage or favorable placement.
• Commercial components are visually separated and carry a direct relationship disclosure.
• PepGuide remains usable when the Rylume feed is unavailable.

How referrals are measured

Commercial links are marked as sponsored for search engines. PepGuide records aggregate events when a reader chooses the source directory, reviews batch records, returns to editorial research, or opens a source listing. Source-directory entry events use only the internal origin path, broad page type, placement, peptide slug when the origin is a profile, and sanitized first-touch campaign fields. Search text and arbitrary query parameters are not included.

Outbound links add a consistent referral source, medium, campaign, placement, and peptide slug to the destination URL. These fields help the operating team understand which research pages lead readers to a listing and whether the link appeared in an image or primary action.

Referral measurement does not change article content or profile rankings.

What to inspect before relying on a source

Commercial documentation should be evaluated independently of the PepGuide article. At minimum, inspect:

• a batch-specific record that matches the listed lot;
• the reported identity and purity methods, results, dates, and testing laboratory;
• storage, handling, and chain-of-custody information;
• clear business identity, contact, return, and correction policies; and
• the compound's legal and regulatory status in the relevant jurisdiction.

The presence of a document is not the same as proof that its contents are complete or accurate.

Future store partners

PepGuide may support additional commercial sources in the future. Any new integration must use the same standardized availability component, direct relationship disclosure, sponsored-link markup, campaign taxonomy, editorial separation, and batch-documentation fields. Payment, promotion, or inventory status cannot determine scientific coverage or conclusions.
