We typically keep 10mg and 30mg vials in stock for the common GLP-1 sequences, though the 5mg size usually has a 2-week lead time if you need smaller quantities. Each vial is sealed under inert gas and shipped with a cold pack during warmer months—dry ice is available on request but adds about $15 to shiping. The COA covers HPLC purity at ≥99%, MS confirmation of molecular weight, and endotoxin below 1.0 EU/mg; we don't run sterility testing since it's non-sterile by design.
Most buyers are metabolic researchers running in vivo studies or cell-based assays, and they pretty much always go with the 30mg vial for the better price per mg. It's also used in formulation work for weight management research, though we've seen some labs push it into custom peptide blends—not something we recommend without proper solubility testing first. The lyophilized powder reconstitutes in water or buffer, but you'll want to aliquot it imediately after reconstitution because of that it degrades faster in solution.
Shipping is typically 3-5 business days domestic, but international orders can take 10-14 days depending on customs clearance for peptide powders, we use insulated boxes with gel packs for cold chain, and the shelf life is 24 months at -20°C desiccated—just don't leave it on the bench for more than an hour or so. The MOQ is 1 vial for most sequences, but we do require a minimum of 10 vials for custom synthesis runs.
Actually, one thing buyers don't always think about is that the peptide's molecular weight varies by sequence—GLP-1(7-36) amide is about 3297 g/mol, while liraglutide base is closer to 3756 g/mol—so your dosing calculations need to account for that. We include teh exact MW on each COA, but we've had labs mix up sequences and underdose their assays. appearance is white to off-white powder, and if it's yellow or clumpy, that's a red flag for moisture exposure.
Solid-phase synthesis with preparative HPLC purification keeps batch-to-batch variation low, typically within 0.5% purity between lots. For research use only, obviously—not for human or veterinary application. The endotoxin level is <1.0 EU/mg, which is tighter than many suppliers' 5 EU/mg spec, but if you need lower for sensitive cell work, we can discuss custom purification at higher cost.
MOQ varies by peptide, but we typically start at 10 mg per vial. If you need a custom amount, just reach out and we can work something out.
Standard lead time is 7-14 business days after order confirmation, depending on batch size and current production schedule. We can expedite if needed.
Yes, every batch comes with a COA that shows HPLC purity (≥99%), MS confirmation, amino acid analysis, and endotoxin levels (<1.0 EU/mg). It's your proof of quality.
Absolutely—we use solid-phase synthesis, so we can tailor the sequence to your specs. Packaging size is flexible too, just let us know the vial quantity or bulk requirement.
Keep it at -20°C in a desiccated environment, sealed in the original vial under inert gas. Avoid moisture and repeated freeze-thaw cycles to preserve stability.
