Quick answers

What is TESA?

Growth-hormone-releasing factor analog. Lyophilized powder, 2mg, 5mg or 10mg per vial.

Is TESA third-party tested?

Yes. Janoshik Analytical, an independent laboratory, tested TESA 10mg. The certificate of analysis is published on the product page with the lab's verification key, so it can be checked against the laboratory's own record. 2 other strengths don't have a published certificate yet.

What strengths of TESA are available, and what do they cost?

TESA comes in 2mg for $22.99 (restocking), 5mg for $39.99 (restocking) and 10mg for $88.00.

How fast does TESA ship?

Orders placed before 2 PM Central ship the same business day, tracked, in insulated packaging. Standard U.S. shipping is free on orders over $300, and international shipping is a flat $50. 1 of 3 strengths is in stock right now.

How should TESA be stored?

Keep the lyophilized vial sealed, dry and away from light. For long-term storage of lyophilized material, −20 °C is the common working standard; 2–8 °C refrigeration suits material in active use. Let a cold vial come to room temperature before opening it, so moisture doesn't condense inside.
