Answers to the most common questions about our products, ordering process, shipping, and research use guidelines.
All Optimus Peptides compounds meet a minimum purity specification of greater than or equal to 99% before dispatch. Purity is documented on each batch Certificate of Analysis.
Yes. A batch-specific Certificate of Analysis is available for every product we supply. The CoA includes measured purity (%), confirmed molecular weight, net weight, and storage conditions.
To request your CoA, please contact us with your order reference number and the batch number printed on your vial. We will provide the CoA promptly by email.
All peptides are supplied as lyophilised (freeze-dried) powder in sealed amber glass vials with tamper-evident closures. Lyophilisation provides maximum stability for long-term storage and ease of reconstitution for research use.
Vials are not pre-reconstituted. You will need to reconstitute the peptide in the appropriate solvent for your research protocol - typically bacteriostatic water for injectable-grade applications, or a suitable research buffer.
Lyophilised (unopened): Store at −20°C in a dry environment, protected from light. Under these conditions, lyophilised peptides are stable for up to 24 months.
Reconstituted: Store at 2–8°C and use within 28 days (14 days for GHK-Cu). Avoid repeated freeze-thaw cycles, which can degrade peptide integrity. Aliquot reconstituted solutions for long-term storage if needed.
All storage recommendations are printed on the vial label and included in the Certificate of Analysis.
The appropriate reconstitution solvent depends on the specific peptide and its intended research application:
Always reconstitute by injecting solvent gently against the vial wall and allowing the powder to dissolve by swirling - do not shake or vortex.
All three are incretin-based metabolic peptides but differ in their receptor target profiles:

No. All products sold by Optimus Peptides are strictly for scientific research and in-vitro laboratory use only. They are not approved by the MHRA, FDA, or any other regulatory authority for human or veterinary administration. They have not undergone the clinical trials required for medical product approval and must not be used for diagnosis, treatment, or prevention of any medical condition.
In the United Kingdom, research peptides that are not designated as controlled substances may generally be supplied for legitimate scientific research purposes. However, the legal status of individual compounds varies and is subject to change. It is the buyer's sole responsibility to verify the legal status of the specific compound they wish to purchase in their jurisdiction before placing an order.
