BPC-157 Research Starter Kit (5 mg · Bac Water · Syringes · Pads)

The peptide in the kit

BPC-157 corresponds to a fifteen-residue partial sequence of body protection compound, a protein characterised in human gastric juice. It contains no cysteine and no classic protease-labile motif, and stability studies report that it survives acidic aqueous conditions longer than most peptides of comparable size — a property that explains why oral and intragastric routes appear alongside parenteral ones throughout the animal literature.

What the literature examines

Why the consumables matter to the data

• Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated withdrawal from one vial defensible; unpreserved sterile water is a single-use diluent.
• Low dead-space 31G insulin syringes with 0.01 mL graduations reduce the volume error that dominates uncertainty when small aliquots are drawn from a 5 mg vial.
• Swabbing the stopper before every entry limits contamination that would otherwise shorten the usable life of a reconstituted preparation.

Scope of the kit

A 5 mg vial is a pilot quantity. It is well matched to method development, concentration-response range finding and short in vitro series; longer study programmes usually move to the 10, 15 or 20 mg vials, where the per-milligram cost is lower and fewer reconstitution events are needed.

Store the peptide vial at −20 °C, sealed and protected from light and moisture, and keep the water, syringes and pads at room temperature in their original packaging. Before reconstituting, let the vial warm to room temperature so condensation does not settle on the powder, then swab both stoppers with a prep pad. Draw the chosen volume of bacteriostatic water and add it slowly down the inner wall of the peptide vial; swirl gently until the cake dissolves and never shake, since foaming shears peptide and traps material on the stopper. Label the vial with concentration, lot and date, refrigerate at 2–8 °C in the dark, use a fresh syringe for every withdrawal, and place used sharps in an approved container.
