Why buy Tesamorelin Research Peptide from TrueBond Labs
Lot certificate, published
An independent third-party lab tested our published tesamorelin lot, confirmed identity and reported HPLC purity of at least 99%. Read the tesamorelin certificate before you order, then check it against the lot code on your vial.
44 residues, tesamorelin only
Tesamorelin is one of the longest peptides we carry, at 44 residues, about one and a half times the length of sermorelin. Each vial holds 10mg of lyophilized tesamorelin in a sealed 3 mL vial, with nothing else blended in, so the certificate covers a single compound.
How it compares
Sermorelin is the first 29 residues of GHRH with nothing added. CJC-1295 No DAC keeps 29 residues and swaps four. Tesamorelin is the longer, modified one. All three are on our research peptides page.
What is Tesamorelin?
Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone built on the full 44-amino-acid sequence, GHRH (1-44). What sets it apart from the native sequence is a trans-3-hexenoyl group attached at the N-terminus, the start of the chain. Hexenoyl is a short six-carbon chain with one double bond, and trans-3 describes where that double bond sits and how it's oriented.
Tesamorelin appears in published laboratory research on growth-hormone-axis signaling. Because it carries the whole 44-residue sequence plus that one added group, it's a distinct compound from the shorter GRF (1-29) analogues, even though its first 29 residues match sermorelin's. It's supplied as freeze-dried powder for in-vitro laboratory research only.

Tesamorelin Research Peptide: frequently asked questions
What is tesamorelin?
Tesamorelin is a 44-amino-acid synthetic GHRH analogue with a trans-3-hexenoyl group on its N-terminus. It's in the same broad class as sermorelin and CJC-1295 No DAC. We sell it as a 10mg lyophilized vial for laboratory research use only, not for human or animal use.
What is the difference between tesamorelin and sermorelin?
Sermorelin is a 29-residue fragment of GHRH with nothing added. Tesamorelin uses all 44 residues and adds a hexenoyl group at the start of the chain. So tesamorelin is the longer, modified one, and sermorelin is the shorter, unmodified one. Our sermorelin vs tesamorelin page lays out the two row by row.
Tesamorelin vs CJC-1295: what's the difference?
Both are GHRH analogues, but they're built differently. CJC-1295 No DAC is 29 residues with four swapped amino acids. Tesamorelin is the full 44-residue sequence with a hexenoyl group added at the N-terminus. Each is sold as its own 10mg vial with its own lot code.
Is your tesamorelin third-party tested?
Yes. An independent US lab tested our published lot. The certificate sits on our lab reports page under its lot code, with the test date and purity figure as the lab printed them.
How should I store tesamorelin?
Keep the sealed vial frozen at −20°C (−4°F) and out of the light. Lyophilized tesamorelin holds for 24+ months under those conditions. Try to avoid repeated freeze/thaw.
Where can I buy tesamorelin in the USA?
You can buy it here. Order before 2PM ET on a weekday and it leaves our Fort Lauderdale, Florida warehouse the same day by USPS with tracking. Guest checkout is open, and a free research account gets you a one-time first-order discount. Buyers must be 21 or older.
