COA PublishedWhat's in the Vial
Add bacteriostatic water slowly along the vial wall. Gently invert 5–6 times — do not shake. Refrigerate at 2–8 °C; use within 30 days. Do not freeze reconstituted solution.
General Protocol Ranges
These are published research ranges — not a prescription. Your physician finalizes your protocol.
Research protocols typically follow a weekly dose escalation: 0.25 mg for 4 weeks, 0.5 mg for 4 weeks, then titrate to 1 mg or 2.4 mg depending on endpoint and tolerability. Once weekly subcutaneous injection in the abdomen, thigh, or upper arm.
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.

Research-grade semaglutide is supplied as lyophilized powder for investigational reconstitution — not as a pre-filled pen device. The active compound is identical, but it is not a finished drug product and is supplied for research use only. A physician must oversee any protocol.
Published preclinical and clinical literature covers HbA1c reduction in T2DM models, body weight reduction in obesity models, cardiovascular risk markers, and emerging neuroprotective signals. Your physician will design a protocol matched to your specific research question.
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.
