Research Only

These products are intended for laboratory research purposes only, and are not for human or animal consumption. The products are not intended to diagnose, treat, cure, or prevent any disease. The products should not be used as a food, drug, cosmetic, or other household use. By accessing this website or purchasing from this website, you agree that that it is your sole responsibility to ensure compliance with applicable laws and regulations within your jurisdiction; and you understand and acknowledge that no information on this website should be construed as medical advice.

We verify every batch of every product through accredited, independent third-party laboratories. Since each product requires unique analytical methods and equipment, we collaborate with specialized laboratories and PhDs in analytical and organic chemistry to design our testing protocols.

Analytical techniques we utilize include: NMR, FTIR, HPLC, LC-MS, GC-MS, TLC, ICP-MS, Gravimetry, UV-Vis, Titration, Melting Point, and Organoleptics.
We primarily test for purity, content, sterility, and endotoxins (LPS).

Lab results are available here: View Lab Results.
If a specific test is outdated or not listed, please contact us.

Variations in color, texture, odor or even biochemical properties may occur due to polymorphy (differences in crystal structure).These variations do not compromise product quality.

Our peptides are provided in lyophilized powder form to ensure maximum stability. In any other format, peptide integrity would rapidly degrade before reaching the customer.

  • Optimal storage: Below –20 °C.
  • Short-term storage: Refrigeration at 4 °C for up to 2 years.
  • Room temperature tolerance: 4–6 weeks with minimal degradation if protected from direct sunlight (suitable for international shipping).

Images on our site display white tops for illustration purposes only. In practice, vial tops may vary in color to help our staff distinguish products during processing.

Lyophilized peptides typically form a solid cake. However, during transit, the cake may break or appear uneven. This is an aesthetic issue only and does not impact quality, potency, or purity.

Some peptides and proteins may appear larger due to buffering requirements. This is normal.

Storage instructions are provided on each product listing and product label.

  • General storage: Store in a cool, dry place away from heat, moisture, and sunlight.
  • Best practice: Refrigeration or freezing is recommended for long-term stability.

Solution-based products may occasionally:

  • Crystallize (form flakes)
  • Precipitate (fall out of suspension)
  • Separate (form layers)
  • Lose homogeneity

This typically occurs during cold transit or accidental freezing. To restore uniformity:

  1. Warm the vial in 50–70 °C water for 5–10 minutes.
  2. Shake vigorously to re-suspend.

If the product does not return to homogeneity, please contact us.

All molecules degrade over time, but proper storage significantly slows this process.

  • Low temperature exposure: Generally safe; may cause precipitation in solutions but does not accelerate degradation.
  • High temperature exposure: Prolonged exposure may accelerate degradation.
    • Example: A product requiring room temperature storage exposed to 115 °F for a few days will not show measurable degradation once properly stored again.
  • Cold-storage products (–20 °C): Short-term exposure (<24h) to ambient temperatures does not significantly degrade the product unless oxygen, moisture, or sunlight are also present.

These products are intended for laboratory research purposes only, and are not for human or animal consumption. The products are not intended to diagnose, treat, cure, or prevent any disease. The products should not be used as a food, drug, cosmetic, or other household use. In the event of accidental exposure or ingestion:

  • Contact your local toxicologist. United States: Poison Help Line — 1-800-222-1222
  • Seek immediate medical attention.
  • Always handle products using proper PPE.
  • Refer to the product’s SDS for safety guidelines.
