Somatostatin (SST-14 and SST-28)14 residuesAGCKNFFWKTFTSCEach bubble = one amino acid. Size = residue mass. Color = chemical class.Somatostatin (SST-14) is the endogenous hormone that suppresses GH, insulin, glucagon, and gastric acid through all five SSTR subtypes. A 1-3 minute half-life limits its use to IV infusion in research and hospital settings. Synthetic analogs handle clinical applications instead.
250mcg · Continuous IV infusion (mcg/hour)
Summary: Add 2mL BAC water to your 0.25mg vial. Draw to 200.0 units on a U-100 syringe for a 250mcg dose. This vial will last 1 doses.

This peptide does not belong in anyone's home refrigerator. Native somatostatin requires continuous IV infusion through a hospital pump because the 1-3 minute half-life means a single subcutaneous injection produces no meaningful blood levels. There is no self-administration protocol that works. For the reconstitution math in clinical settings: a standard 3 mg vial dissolved in 50 mL of 0.9% NaCl gives 60 mcg per mL. Running at 250 mcg per hour means 4.2 mL per hour on the IV pump. Running at 500 mcg per hour means 8.3 mL per hour. Research-grade vials (0.25 mg) reconstituted in 0.5 mL bacteriostatic water yield 500 mcg per mL for bench studies. The detail most people miss: rebound monitoring is just as important as infusion monitoring. Stopping the drip isn't the end of the clinical event. GH, insulin, and glucagon all spike above baseline for one to two hours after cessation. Have dextrose 50% drawn up before you turn off the pump. Store lyophilized powder at minus 20 degrees Celsius; reconstituted solution lasts 24 hours at 2-8 degrees Celsius maximum. Do not refreeze.

Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.
