First order? Any size. A 6 mL bottle of bacteriostatic water and the shipping come off automatically at checkout — or put the bottle's $10 toward the 30 mL and pay the $15 difference. First orders only. One bottle per order.
Add ons
A 6 mL bottle is included free on a first order. Tick this to upgrade to the 30 mL bottle instead: its $25 less the free bottle's $10, so $15 more at checkout. Not your first order? It is $25.
A 10 mg vial takes about 3 mL — one 30 mL bottle covers about 10.

Why this one
Three receptors. One molecule. GLP-3 (RT) reset what a metabolic reference compound looks like, and the literature has been catching up ever since — single- and dual-agonist peptides are now routinely characterised against it rather than the other way round.
That is what it is for here: receptor binding and downstream signalling in cell-based assays, incretin pathway crosstalk, and comparative work across the agonist class. Supplied lyophilized, so the concentration is yours to set.
Where it shows up in the literature
Receptor pharmacologyBinding and functional response at GLP-1, GIP and glucagon receptors in transfected cell systems.
Pathway crosstalkHow simultaneous engagement of three receptors differs from single-receptor agonism.
Metabolic signallingDownstream cAMP and second-messenger readouts in cultured cells.
Comparative workSide-by-side characterisation against dual and single incretin agonists.

Handling
Store sealed vials at 2–8°C for short-term use, or at −20°C for long-term storage, and protect from light. Reconstitute with the diluent your protocol specifies; bacteriostatic water is the common choice where a vial will be entered more than once.
Allow refrigerated material to reach room temperature before opening, and avoid repeated freeze-thaw cycles once in solution.
Certificate of analysis
Every lot is tested by an independent ISO-accredited laboratory. The lot number on your vial resolves at the testing laboratory directly, so the purity figure never has to come from the party selling it to you.
