Should peptides be injected subcutaneously or intramuscularly?

Every compound on this site sold to individuals is described, by sellers and in the plans people actually follow, as a shot under the skin using an insulin syringe. That is also what this site's mixing calculator assumes. Under the skin means into the fat layer, not into muscle. No published study in people has compared the two ways for any compound this site tracks.
