Tesamorelin and DSIP (delta sleep-inducing peptide) are studied in the preclinical and clinical literature for their proposed roles in growth-hormone-axis regulation and sleep-related signalling, respectively. This category brings together research peptides intended exclusively for laboratory investigation into growth hormone releasing hormone (GHRH) activity, lipid metabolism, and sleep-architecture pathways.

Tesamorelin is a synthetic GHRH analogue studied for its proposed stimulatory effect on endogenous growth hormone release, and has a comparatively well-documented body of clinical research relative to many peptides in this space, most of it originating from studies into lipodystrophy and metabolic research contexts. DSIP, by contrast, is a shorter peptide studied mainly for its proposed influence on slow-wave sleep and circadian signalling, though the underlying mechanism remains less well characterised and the evidence base is considerably smaller.

Given the different research contexts for these two compounds, researchers should take care not to assume that findings relevant to one extend to the other simply because both are grouped together here for catalogue purposes; each should be evaluated against its own body of literature.

Every product in this category is independently HPLC-tested for identity and purity, with a Certificate of Analysis (COA) available for every batch. As with all peptide research materials, we recommend reviewing the COA before beginning a protocol and storing material according to the supplied guidance to preserve stability between uses.

Researchers should document the specific batch and formulation used in any protocol, and treat manufacturer-stated concentration as a claim to verify against the COA rather than an assumption, particularly where results are intended to be compared against other research groups’ findings.

All products in this category are sold strictly for laboratory research use (RUO) and are not intended for human or animal consumption. Nothing on this page constitutes medical advice, a dosing recommendation, or an endorsement of personal use.
