Tesa Lyophilized Research Peptide
Tesa is a stabilized analogue of full-length growth hormone-releasing hormone (GHRH 1-44), modified at the N-terminus to resist enzymatic breakdown. It is supplied in 5mg, 10mg, 20mg and 30mg lyophilized vials.
Research Applications
Tesa is studied for GHRH receptor activation and the downstream regulation of growth hormone and IGF-1 signaling. Lab research focuses on pituitary signaling, lipid metabolism pathways, and comparisons with shorter GHRH fragments.
Why Researchers Choose It
- Full-length, stabilized GHRH analogue
- Four vial sizes up to 30mg
- Lyophilized for stability in storage and transit
- Batch-tracked with third-party COA testing

Frequently Asked Questions
How is Tesa different from Sermo?
Tesa is based on the full 44–amino acid GHRH sequence with a stabilizing modification, while Sermo uses the shorter 1-29 fragment.
Is there a blend with Ipamo?
Yes. A combined Tesa/Ipamo vial is also available.
Does this product come with a Certificate of Analysis?
Yes. Every batch is supported by independent third-party analytical testing confirming identity and purity.
What does lyophilized mean?
Lyophilized means freeze-dried. Removing water this way gives the peptide a stable powder form that holds up well in storage and shipping.
Is this product approved for human or animal use?
No. It is sold strictly for in-vitro laboratory research.
