COA PublishedWhat's in the Vial
Add bacteriostatic water slowly. Gently invert — do not shake. Refrigerate at 2–8 °C; use within 30 days. Tirzepatide is a larger peptide — allow 2–3 minutes for complete dissolution.
General Protocol Ranges
These are published research ranges — not a prescription. Your physician finalizes your protocol.
Published dose escalation protocols begin at 2.5 mg once weekly for 4 weeks, increasing by 2.5 mg every 4 weeks to a maximum of 15 mg. Once weekly subcutaneous injection. Physician oversight required for escalation decisions.
Why Physician Oversight?
SourcePeptideCo does not dispense research-grade peptides without licensed physician oversight. This isn't a formality — these compounds interact with individual biochemistry in ways that require clinical judgment.
Our process: you submit a consultation intake, a coordinator matches you with a licensed physician in your state within one business day, and the physician designs a protocol appropriate to your research goals and health profile.
No physician sign-off, no order. That's the standard we hold to.

GIP (glucose-dependent insulinotropic polypeptide) is an incretin hormone that potentiates insulin secretion and promotes adipocyte differentiation. Activating both GIP and GLP-1 receptors simultaneously produces additive or synergistic metabolic effects compared to GLP-1 alone — particularly in weight loss models.
Head-to-head clinical studies (SURMOUNT, SURPASS) showed tirzepatide achieving greater mean body weight reduction and HbA1c reductions vs. semaglutide at comparable time points. Individual response varies — your physician will assess which compound fits your protocol.
Lyophilized peptide powder: store at −20 °C for long-term (up to 24 months) or at 4 °C for up to 6 months. Once reconstituted: refrigerate at 2–8 °C, use within the timeframe specified on your product (typically 14–30 days). Avoid repeated freeze-thaw cycles.
Our lyophilized peptides carry a 24-month expiry from manufacture date as printed on the batch label. Each COA confirms the exact lot date and expiry. Once reconstituted, shelf life drops significantly — see the reconstitution notes for your specific compound.
SourcePeptideCo operates through a licensed physician network. Peptide research compounds can interact with medications, contraindicate with certain conditions, and require clinical judgment for correct dosing. We don't sell without physician oversight — not as a formality, but because the oversight is part of the value.
A Certificate of Analysis (COA) documents the test results for a specific production batch. It certifies identity (the peptide is what we say it is), purity (by HPLC-UV), molecular mass (by LC-MS), endotoxin levels, and sterility. Every batch is tested by an independent ISO 17025-accredited laboratory.
