BioSuppress is a synthetic peptide of approximately 39 amino acids in length, possessing a linear structure. It functions as a dual receptor agonist that targets the glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) pathways.
This unique design of the peptide allows for protection against rapid degradation via DPP-4 mediated enzymatic cleavage, high bioavailability, and an extended biological half-life for less frequent administration in research settings. Notably, the GIP receptor agonism is believed to counteract the emetic effects known to arrive from GLP-1 receptor agonism in preclinical models.

Lyophilized Peptides:
These peptides are freeze-dried, a process that not only extends shelf life but also preserves the purity and integrity of the peptides during storage. We do not use any fillers in this process.
BioSuppress possesses unique pharmacokinetic characteristics that separate it from other incretin receptor agonists. While its binding affinity for the GIP receptor is near equivalent to that achieved by native GIP, its binding for the GLP-1 receptor is 5 times weaker compared to native GLP-1. Additionally, it exerts a lower degree of beta-arrestin recruitment upon binding to the GLP-1 receptor compared to native GLP-1.
This allows for a reduction in side effects due to GIP’s anti-emetic properties, along with greater glucose-dependent insulin secretion due a combination of decreased GLP-1 receptor desensitization and prolonged activity at the GLP-1 receptor.
Additionally, there are some shared properties between GLP-1 receptor and GIP receptor agonism that allow for synergistic effects with respect to improving insulin sensitivity, reducing hunger, and decreasing glucagon secretion. While GLP-1 receptor agonism leads to delayed gastric emptying, GIP receptor agonism allows for glucose disposal in white adipose tissue and the regulation of bone metabolism.
This multi-receptor incretin activity allows for deeper exploration into metabolic signaling analysis, along with a reduction in body weight and blood sugar levels beyond what targeting either incretin receptor can achieve in isolation.
BioSuppress was designed to model dose-dependent pathway activation for controlled research environments within the following contexts:
Appetite Signaling & Weight Regulation: Central and peripheral mechanisms influencing satiety, caloric intake, energy balance, and feeding behavior
Glucose Regulation & Insulin Dynamics: Post-prandial glucose regulation, modulation of glucagon signaling, interactions between incretin pathways, glucose-dependent insulin responses.
Body Composition Dynamics & Metabolic Efficiency: Effects on fat mass, lean mass preservation, nutrient partitioning and metabolic adaptations.
Cardiometabolic Markers: Secondary pathways associated with lipid metabolism, inflammation, and metabolic health indicators.

Certificate of Analysis (COA) for Every Batch
A Certificate of Analysis (COA) is a document that verifies a compound’s identity, purity, and batch quality through independent laboratory testing. Every compound from BioLongevity Labs ships with a COA tied to its specific batch, so researchers can confirm exactly what they received before it enters a protocol.
Each COA reports results from third-party laboratory analysis, including:
- High-performance liquid chromatography (HPLC) for purity, typically confirmed at 99% or higher
- Liquid chromatography mass spectrometry (LC-MS) for molecular identity and mass confirmation
- Sterility and endotoxin screening where applicable
- Chemical contaminant and residual solvent checks
COAs are sourced from independent certified labs rather than in-house testing alone, giving researchers a verifiable record of molecular integrity for each batch. All compounds are supplied for research use only.
