Frequently Asked Questions

No. All products sold by Ascend Labs 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.

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 utilized 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).

Certificates of Analysis (COA) are available upon request. If you need a specific test result, please contact us at support@ascendlabs.com.

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.

• 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)

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

Yes. 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 in the vial due to buffering requirements. This is normal.

Some liquid products may crystallize, precipitate, separate into layers, or lose homogeneity. To restore:

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

• Low temperature exposure: Generally safe; may cause precipitation in solutions but does not accelerate degradation
• High temperature exposure: Prolonged exposure may accelerate degradation. However, 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

• 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

Orders placed before 12:00 PM PST typically ship the same day (about 90% of the time). Orders placed after 12:00 PM PST will ship the following business day.

Our shipping hours are Monday–Friday, 9:00 AM to 5:00 PM PST. We do not ship on Saturdays, Sundays, or federal holidays.

Total delivery timeframes:

• Standard: 1 day processing + 3–6 days shipping = 4–7 business days
• Express: 1 day processing + 2–4 days shipping = 3–5 business days
• High Volume Periods: 2–3 days processing + 3–7 days shipping = 5–10 business days

All timeframes are estimates. Actual delivery times may vary due to weather, holidays, order volume, or courier delays beyond our control.

Once your order ships, you will receive a confirmation email containing your tracking number. You can use this tracking number to track directly with the corresponding courier.

If your label has been printed and there has been no tracking update, it most likely means we're still processing your order. Please check the tracking again in 2–3 days. If there are still no updates after that time, contact us.

Once an order is placed, we have a very limited window to modify or cancel it due to our commitment to rapid shipping times. We cannot guarantee that cancellations or modifications will be possible; however, we will make our best attempts to accommodate if possible, with no guarantees.

Please double-check your shipping address carefully, as entering an incorrect address constitutes user error and is not the responsibility of Ascend Labs.

If tracking shows delivered but you haven't received your package:

1. Check with neighboring suites, facilities, or building reception
2. Contact the courier's local office for GPS delivery coordinates and recipient confirmation
3. If the courier confirms correct delivery, allow 1 week for the package to appear before contacting us
