Our Mission
At Optimal Bio Labs, we are driven by curiosity about how biology works. We created this company to provide the scientific community with the tools they need to study the building blocks of life.
Our team is fascinated by the science of aging and how the body functions at a cellular level. We know that as organisms age, their biological processes change. Researchers are working hard to understand things like metabolic pathways (how we use energy), tissue studies, and cellular communication. We are here to support that discovery.
We supply 99% pure peptides strictly for laboratory research. Peptides are short chains of amino acids commonly studied for their structural and biochemical properties in controlled research environments. By providing high-purity compounds, we help researchers get accurate data in their experiments.
Please Note: All products from Optimal Bio Labs are for Research Use Only (RUO). They are intended for laboratory, analytical, and in vitro testing. They are not food, medicine, or supplements. They are not approved by the FDA for human or veterinary use and are not intended to diagnose, treat, or cure any condition.

Do you offer custom synthesis or wholesale orders?
Yes. We can quote custom research sequences and bulk orders for Research Use Only (RUO) applications. Please contact us with project details, target quantity, and timeline.
When the water is added all the powdered peptide is not dissolving – why?
Research peptide compounds may be supplied in lyophilized form, which can appear unchanged immediately after liquid contact in laboratory settings. Optimal Bio Labs does not provide guidance on reconstitution, preparation, or administration. Researchers should follow protocols approved by their institution or laboratory SOPs
My vial appears empty—why?
Our research compound peptides are supplied as lyophilized powder without fillers. At 2–10 mg, the material can appear as a tiny pellets or cluster of powder on the glass. This is normal. Each lot is accurately weighed during filling and verified.
There’s a problem with my order—how do I get help?
Use the website contact form or email support@OptimalBioLabs.com. Include: Your name, email, and order number A brief description of the issue (missing/incorrect/damaged) Clear photos of the shipping box, packing materials, and any vial labels/lot numbers. We typically respond within 24–48 hours (Mon–Fri) and resolve issues promptly.
I haven’t received a tracking number—what should I do?
We email a tracking link as soon as a shipping label is created. Please: Check your spam/junk folder. Allow 1 business day for order processing; carrier scans can take another 24–48 hours to appear. If it’s been more than 2 business days since your confirmation email and you still don’t see tracking, contact support@OptimalHealthLab.com and […]

What does “Research Purposes Only” (RUO) mean?
RUO means the product is supplied for research and development—for in-vitro work, assay development, method validation, education, or other non-clinical laboratory uses. RUO products are not for human or animal administration, clinical use, or diagnostic use.
Do you provide reconstitution or dosing instructions?
No. We do not provide guidance on reconstitution, dosing, or administration. Use is restricted to laboratory research.
Are these products FDA-approved?
No. These items are not FDA-approved drugs, devices, foods, or cosmetics and are not intended to diagnose, treat, cure, or prevent any disease. Any FDA approvals that may exist for specific peptides in drug products do not apply to our RUO materials.
Who are these products for?
Our research compounds are sold sold exclusively for laboratory research purposes (RUO) to qualified purchasers operating within approved research environments. They are not for human or veterinary use, administration, compounding, or household/consumer applications.
How are your products tested?
Each lot is verified for identity and purity before released from the manufacture. In addition to the manufacture testing for purity, our products also have Certificate of Analysis (COA) from 3rd party testing companies located in the US. Our compounds are tested using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) for purity. Some third-party […]
