FAQs

Peptides—short chains of amino acids—form the very building blocks of proteins and act as powerful messengers throughout the body. By tuning key biological pathways, they can promote youthful, firm skin, help dial down inflammation, and support healthy weight regulation.

Research peptides and compounds are substances used in scientific and medical research to study biochemical and physiological processes. These products are not approved for human use or consumption and are intended solely for in vitro and lab research purposes only.

Absolutely. Every compound we provide is accompanied by third-party COAs (Certificates of Analysis) verifying purity, identity, and safety for research. Our commitment to quality ensures researchers get accurate and reproducible results.

No. All products from Optim Chems are not intended for human use and are sold strictly for laboratory research only. They are not drugs, supplements, or treatments.

At Optim, we formulate NAD⁺ to the highest purity—but even the best preparations can sometimes crystallize if concentration, temperature or humidity fluctuate. Here’s how to get your solution back to full strength and keep it that way:

1. Why Crystallization Happens

• Over-concentration: Evaporation or high initial concentration can push NAD⁺ past its solubility limit.

• Low temperature: Chilling below room temperature encourages crystal formation.

• Moisture & light exposure: Humidity or UV can destabilize the solution.

2. Gentle Redissolution

1. Prepare a 37 °C water bath (warm—but not hot).

2. Submerge the vial (cap tightly closed) for 5–10 minutes.

3. Gently invert or swirl the vial—avoid vigorous shaking.

4. Confirm clarity: Once all crystals dissolve, the solution should be uniformly clear.

Tip: If stubborn crystals remain, add a small volume of bacteriostatic water (e.g. 0.1–0.2 mL) to lower the concentration before repeating the warm-bath step.

3. Optim Storage Best Practices

• Temperature: 2–8 °C (refrigerated); avoid freeze-thaw cycles.

• Light: Keep in amber vials or store in darkness.

• Humidity: Store in a desiccated cabinet or sealed container.

• Concentration: If you routinely see crystals, dilute to ≤10 mg/mL.

By following these steps, your Optim NAD⁺ will remain stable, clear, and ready for precise research applications.

Q1: What is peptide reconstitution?
A1: Peptide reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide into a sterile liquid solvent to create a usable research solution. This is a standard step before applying peptides in experimental protocols.

Q2: How do I reconstitute a 10 mg peptide?
A2: A typical guideline is to add 1 mL of solvent per 10 mg of peptide. This results in a 10 mg/mL solution—a common concentration in research settings.

• For reference:
  • 2.5 mg = 25 IU
  • 5 mg = 50 IU
  • 10 mg = 100 IU

Q3: What solvent should I use?
A3: Solvent selection depends on the peptide’s solubility. The most commonly used solvents include:

• Bacteriostatic Water (0.9% benzyl alcohol): Ideal for extended storage

• Sterile Water for Injection (SWFI): Best for immediate use

• Acetic Acid (0.6%–1%): Helpful for stubborn peptides that resist dissolving

Q4: How do I properly reconstitute the peptide?
A4: Follow these steps for safe and effective reconstitution:

1. Sanitize your workspace and tools to maintain sterility.

2. Add solvent slowly: Use 1 mL per 10 mg, 2 mL for 20 mg, or 3 mL for 30 mg.

3. Dissolve gently: Tilt or swirl the vial—do not shake vigorously to avoid damaging the peptide bonds.

4. Inspect the solution: It should be clear. If particles remain, gently swirl again and allow more time to dissolve.

Q5: How should I store reconstituted peptides?
A5: After reconstitution, peptides should be aliquoted and stored at -20°C to -80°C to avoid degradation. Minimize freeze-thaw cycles by dividing into smaller portions if possible.

Q6: Can I adjust the solvent volume?
A6: Absolutely. You can modify the reconstitution volume to achieve your desired concentration.
For example:

• Using 2 mL with 10 mg = 5 mg/mL

• Using 0.5 mL with 10 mg = 20 mg/mL
  Always adjust your dosing calculations accordingly based on the final concentration.
