About InhousePep

InhousePep is an independent guide for researchers who buy peptides from online suppliers. We read what each supplier publishes about testing, labeling and policies, and we explain the paperwork in plain language.

What we cover

We cover suppliers that sell peptides and other research compounds for laboratory research. Each supplier file sets out who runs testing, whether certificates of analysis are batch-specific, what methods are used, how products are labeled and what the shipping and refund terms say. Our guides explain how to read that paperwork so you can check it yourself.

What we don't cover

We don't publish dosing, injection, stacking or cycling information, and we don't describe effects in people or animals. Research peptides sold online are not approved medicines. If you are looking for treatment, speak to a licensed clinician about approved options.

Who we are

InhousePep is an independent publication. We are not a supplier, we don't sell peptides and we don't accept payment for scores. Supplier links on this site are affiliate links; our disclosure explains how that works.
