Most buyers coming to us have tried the 10mg first, and it's basically where you'll see the clearest results for most metabolic research setups—though the 5mg works fine for smaller-scale work if you're just starting out.
We run HPLC, and the 99% purity is tighter than what you'll find form most generic peptide suppilers, so you're not chasing impurities that mess with your data.

Storage at -20°C is non-negotiable, and we ship with dry ice and insulated packaing (usually 3-5 days to most destinations), but confirm lead time if you're in a remote area since customs can add a week or so.
Actually, what it does is target both GIP and GLP-1 pathways simultaneously—better than relying on a single agonist for glycemic control studies, though it's not suited for acute toxicity work since the half-life is long.

We've handled enough orders to know the 30mg vial is more economical for frequent users, but teh 2mg is easier if you're testing with minimal waste.
Documentation includes COA and SDS with every shipment, and we usually have stock on common sizes, but the 15mg and 20mg vials sometimes need a couple extra days.
We don't enforce a strict MOQ — you can order as little as a single vial, even for the 30mg size. Bulk orders get better per-unit pricing, though.
Yes, we include a COA with every shipment showing the 99% purity, appearance, and other specs. You can request it before ordering if you'd like to verify first.
Store them at -20°C in a freezer. Once reconstituted, keep it refrigerated at 2-8°C and use within a few days for best stability.
We can do custom vial sizes for bulk orders — just reach out with your required mg/vial and quantity. Lead time for custom packaging is typically 2-3 weeks.
Standard orders ship within 3-5 business days after payment confirmation. Express shipping options are available if you need it faster.
