What exactly is Tirzepatide, and why do research programs pick the 30mg tier?
Tirzepatide is a 39-amino-acid dual receptor agonist that engages both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. It has been studied extensively in pre-clinical incretin-axis and glycemic-control research where hitting both receptor arms at once is the design variable. The 30mg per vial tier is Prescott’s standard research tier — enough peptide mass to hold a stable working stock across several weeks of dosing without stepping up to the 60mg extended-cohort format.
What does this specific lot’s CoA cover?
Every Tirzepatide lot is characterised by reverse-phase HPLC for peptide purity and by mass spectrometry against the theoretical 39-residue monoisotopic mass, including confirmation of the C20 fatty-acid diacid side chain. Lot-specific certificates of analysis are being catalogued and will be posted to the product page as they are released.
How do I reconstitute a 30mg Tirzepatide vial?
- Warm the vial to room temperature and clean the stopper with an alcohol swab.
- Draw 1 to 2 mL of bacteriostatic water into a sterile syringe.
- Inject slowly against the vial wall so the lyophilized cake wets from the outside in.
- Rotate — do not shake — until the solution is fully clear.
- Store the reconstituted vial at 2 to 8 °C and use within 30 days.
Tirzepatide 30mg vs the 60mg TR60 tier
TR30 is the standard research tier for cohorts of ordinary size or dosing schedules that fit inside a several-week working stock. TR60 doubles the peptide mass per vial and is the extended-cohort choice — bulk in-vitro incubations, long dose-ranging series, or programmes wanting to cut per-vial reconstitution overhead in half. Both tiers are the same molecule; the pick is a logistics call.
How does Tirzepatide compare with Retatrutide?
Tirzepatide is a dual GIP + GLP-1 receptor agonist. Retatrutide (Prescott SKU RT10) is a triple agonist that adds a glucagon receptor arm to the same GIP + GLP-1 pair. Programmes comparing double- vs triple-incretin coverage typically stock both molecules and treat receptor coverage as the independent variable.
