Everything you need to know about research peptides, ordering, and handling your products safely.
General Questions
What are peptides?
Peptides are short chains of amino acids — the same building blocks that make up proteins in your body. Many occur naturally and play important roles in cell-to-cell signaling. The peptides sold by LuxeX Labs are synthetic versions supplied in lyophilized (freeze-dried) powder form for research purposes.
What does “For Research Use Only” mean?
All products sold by LuxeX Labs are intended strictly for laboratory research and scientific study. They are not approved by the FDA for human consumption, and we do not make any medical claims. By purchasing, you confirm you are a qualified researcher using these compounds in a research context only.
What does lyophilized mean?
Lyophilized means freeze-dried. Peptides are supplied in this powder form because it extends shelf life and stability during shipping and storage. Before research use, the powder must be reconstituted (dissolved) in a suitable liquid — typically bacteriostatic water.
Are your peptides third-party tested?
Yes. All of our peptides are verified by Janoshik Analytical using HPLC and LC-MS testing to confirm identity and purity. You can find the Certificate of Analysis (COA) linked directly on each product page. If it’s not tested, we don’t sell it.
What is a Certificate of Analysis (COA)?
A COA is a document from an independent third-party laboratory verifying a product’s identity, purity, and quality. Our COAs are conducted by Janoshik Analytical, one of the most respected testing labs in the research peptide space. Every COA is linked on the respective product page.
Handling & Reconstitution
What is bacteriostatic water and do I need it?
Bacteriostatic water (BW) is sterile water containing 0.9% benzyl alcohol, which prevents bacterial growth and allows the same vial to be accessed multiple times safely. It is the standard reconstitution solution for research peptides and is strongly recommended over plain sterile water. We sell it in 3mL and 10mL vials.
How do I reconstitute a lyophilized peptide?
Reconstitution is the process of dissolving the freeze-dried powder in bacteriostatic water. General process:
- Gather your peptide vial, bacteriostatic water, and a clean insulin syringe.
- Wipe both vial tops with an alcohol swab and let dry.
- Draw the desired amount of bacteriostatic water into the syringe.
- Insert the needle at an angle and slowly push the water down the inside wall of the vial — do not inject directly onto the powder.
- Do not shake. Gently swirl or roll the vial until the powder is fully dissolved. The solution should be clear.
- Store the reconstituted vial in the refrigerator at 2–8°C.
How much bacteriostatic water should I use?
The amount of bacteriostatic water used determines the concentration of your solution. A common starting point is 1–2mL per vial, but the exact volume depends on the peptide’s mass and the concentration needed for the research protocol. Use a reconstitution calculator to find the right ratio.
What syringes do I need?
Standard insulin syringes (U-100, 1mL) with a 29–31 gauge needle are commonly used in research for drawing bacteriostatic water and handling reconstituted solutions. These are available at most pharmacies without a prescription.
Storage
How should I store my peptides?
Lyophilized peptides should be stored in a cool, dry place away from direct light. For long-term storage, keep them in the freezer at -20°C. Once reconstituted, store the solution in the refrigerator at 2–8°C and avoid repeated freeze-thaw cycles, which can degrade peptide quality.
How long do reconstituted peptides last?
When reconstituted with bacteriostatic water and refrigerated at 2–8°C, most peptides remain stable for 4–6 weeks. Dry lyophilized peptides stored in the freezer can last 1–2 years or longer. Always check for visible changes in color, clarity, or particulates before research use.
Do peptides need to stay cold during shipping?
Lyophilized peptides are stable at room temperature for short periods and are routinely shipped without refrigeration. The freeze-dried form is specifically designed to be stable in transit. Once received, transfer them to a refrigerator or freezer for storage.
Products
What is the difference between CJC-1295 with DAC and without DAC?
Both are GHRH analogues, but the key difference is duration. CJC-1295 without DAC has a short half-life (~30 minutes), producing a sharp, pulsatile GH release. CJC-1295 with DAC incorporates a Drug Affinity Complex that extends its half-life to approximately 6–8 days, allowing for less frequent dosing in research protocols.
What is the difference between BPC-157 and TB-500?
Both are studied for tissue repair, but through different mechanisms. BPC-157 is researched primarily for gut healing, tendon repair, and local inflammation reduction. TB-500 (Thymosin Beta-4) acts more systemically, promoting cell migration, new blood vessel formation, and muscle fiber repair throughout the body. Their mechanisms are thought to be complementary, which is why we offer them as a combined product.
Can peptides be mixed together?
Some peptides are commonly studied together in research protocols — such as CJC-1295 and Ipamorelin, or BPC-157 and TB-500. Whether they can be combined depends on compatibility and the specific research being conducted. Always consult relevant scientific literature for guidance on your protocol.
