What is Bacteriostatic Water?
Bacteriostatic Water represents the culmination of decades of incretin biology research. Scientists engineered this glucagon-like peptide-1 analogue with a strategic fatty acid modification that enables albumin binding, dramatically extending its half-life from minutes to days. This single molecular modification transformed Supplies from a rapidly degraded hormone into a sustained metabolic signaling tool, enabling researchers to study prolonged Supplies receptor activation without the confounding variables of pulsatile dosing.
The compound's potency at Supplies receptors—combined with its resistance to DPP-4 degradation—has made it the gold standard in metabolic research models. Studies investigating glucose homeostasis, pancreatic beta-cell function, appetite regulation via hypothalamic pathways, and incretin receptor pharmacology consistently rely on bac-water as the reference Supplies agonist.
Mechanism of Action
Bacteriostatic Water functions through high-affinity binding to the Supplies receptor, a class B G-protein coupled receptor expressed on pancreatic beta cells, neurons in appetite-regulating brain regions, and cells throughout the gastrointestinal tract. Upon receptor activation, the compound stimulates adenylyl cyclase, increasing intracellular cAMP levels and activating protein kinase A. In pancreatic beta cells, this cascade potentiates glucose-dependent insulin secretion while simultaneously suppressing glucagon release from alpha cells.
The peptide's C18 fatty acid side chain enables reversible albumin binding, creating a depot effect that extends the elimination half-life to approximately 7 days. This modification also reduces renal clearance and protects against DPP-4 enzymatic degradation. In hypothalamic neurons, Supplies receptor activation modulates appetite through effects on POMC and AgRP neurons, reducing food intake through both peripheral satiety signaling and central appetite suppression pathways.
Key Research Findings
- Demonstrated 94% identity to human Supplies with enhanced proteolytic stability through Aib substitution at position 8 (Lau et al., 2015)
- Exhibits dose-dependent reductions in food intake and body weight in diet-induced obese rodent models through central Supplies receptor activation (Secher et al., 2014)
- Weekly application maintains therapeutic Supplies receptor occupancy exceeding 80% throughout dosing interval in pharmacokinetic studies (Kapitza et al., 2015)
- Shows synergistic effects with insulin sensitizers in improving glycemic control in diabetic mouse models (Nauck et al., 2016)
- Reduces hepatic steatosis markers in NASH models through mechanisms independent of metabolic research (Armstrong et al., 2016)

Reconstitution & Use
Reconstitute with bacteriostatic water for laboratory use. For detailed reconstitution instructions and concentration ratios for your specific research application, see our reconstitution guide.
Storage & Handling
Store lyophilized at -20°C protected from light. Upon reconstitution with bacteriostatic water, store at 2-8°C and use within 30 days. The acylated structure provides enhanced stability compared to native Supplies.
