Name: Testagen
SKU: TESTA-TESTAGEN
Price: 80.00 USD
Availability: InStock

Original price was: $100.00.Current price is: $80.00.

Testagen is a synthetic tetrapeptide (Lys-Glu-Asp-Gly, KEDG) from the Khavinson short-peptide series. It contains no steroid nucleus and is unrelated to androgens chemically; it is a four-residue peptide. It has the molecular formula C₁₇H₂₉N₅O₉, a molecular weight of approximately 447.44 g/mol. Its sequence is Lys-Glu-Asp-Gly (KEDG). KEDG is reported to penetrate cultured cells and their nuclei, to bind deoxyribooligonucleotides with sequence preference, and to associate with histones H1, H2B, H3 and H4. These are in-vitro and modeling findings. Supplied as a white to off-white lyophilized powder, stored refrigerated at 2–8 °C. This product is strictly for research purposes only.

WHOLESALE KIT — IMPORTANT ORDER INFORMATION

This is a wholesale 10-vial program. Kits are fulfilled directly through our international manufacturing and fulfillment network rather than from standard retail inventory, allowing us to offer genuine bulk pricing.

Please review the following before adding a kit to your cart:

Longer processing time: Wholesale kit orders may require 5–10 business days of processing before carrier transit begins. This is longer than standard single-vial orders.
Ships internationally: Wholesale kits are fulfilled from Hong Kong and shipped worldwide. International transit and customs processing may add additional delivery time.
Wholesale packaging: Vials may arrive without individual retail packaging or retail-style labels. Product identification and batch information should be verified using your order details and the applicable COA / batch documentation.
Lyophilized powder appearance may vary: Freeze-dried powder may shift, fragment, or separate during transportation. Changes in the physical appearance of the lyophilized puck are not, by themselves, considered a product defect.
