Overview
Description
A growth hormone–releasing peptide researched for supporting endogenous growth hormone signaling with a strong emphasis on visceral-fat–related pathways. Often selected for waistline refinement goals while preserving recovery and lean mass support.
Tesamorelin is commonly explored in research for metabolic and abdominal fat distribution pathways, making it a premium option for body-composition optimization and longevity-focused protocols.
Scientific Overview
Tesamorelin is a synthetic growth hormone–releasing hormone (GHRH) analog designed to stimulate pulsatile growth hormone secretion from the pituitary. It has been studied for effects on visceral adipose tissue and metabolic biomarkers in experimental settings, with ongoing research interest in body composition, recovery-related pathways, and downstream IGF-1 dynamics.

Frequently asked questions
Yes. Every batch of Tesamorelin 10mg undergoes independent third-party testing using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). The Certificate of Analysis is published and accessible from the product page.
Tesamorelin 10mg sold by MHS Longevity is verified to 99%+ purity, with the result documented in each batch's Certificate of Analysis. Anything below that threshold is rejected before release.
The Certificate of Analysis for Tesamorelin 10mg is available directly from the product page and on our Third-Party Test Results page. Each COA includes the batch identifier, test date, testing method, and verified purity percentage.
Tesamorelin 10mg ships from our US-based facility with standard or expedited options. Orders over $150 qualify for free standard US shipping. All orders are packaged discreetly with documented handling protocols.
No. Tesamorelin 10mg is supplied strictly for laboratory research purposes only. It is not approved by the FDA for human or veterinary use, and it is not intended to diagnose, treat, cure, or prevent any disease.
MHS Longevity is a veteran-owned operation focused on pharmaceutical-grade research compounds. We source from vetted manufacturers, batch-test independently with HPLC and Mass Spectrometry, and publish every Certificate of Analysis. Pricing is transparent and the testing process is documented end-to-end.
Tesamorelin has a molecular weight of approximately 5135.8 g/mol, with the empirical formula reported on each batch's Certificate of Analysis. The N-terminal trans-3-hexenoyl modification contributes a specific mass shift relative to unmodified GHRH(1-44) and is confirmed by Mass Spectrometry.
All three are GHRH-receptor agonists, but they differ in length and modification. Sermorelin is unmodified GHRH(1-29). CJC-1295 No-DAC is Modified GRF(1-29) — the same length as Sermorelin but with four stabilizing substitutions. Tesamorelin is the full 44-amino-acid GHRH(1-44) with an N-terminal acyl modification. The longer length and the N-terminal modification together give tesamorelin distinct pharmacokinetic properties in the published research.
Tesamorelin is sent to an independent third-party laboratory for HPLC and Mass Spectrometry analysis before each batch is released. The lab's identifier and test date are published on the Certificate of Analysis for that batch, including explicit confirmation of the N-terminal modification.
FDA-approved pharmaceutical preparations of tesamorelin are formulated injectable products produced under pharmaceutical-manufacturing standards and distributed through prescription channels for a specific approved clinical indication. Research-grade Tesamorelin is a lyophilized peptide supplied for laboratory study only — it is not formulated, not pharmaceutical-grade, and not approved for human use. The molecule itself is the same active species; the regulatory status, formulation, and intended use are entirely different.

Research details — Tesamorelin 10mg
Tesamorelin is a synthetic 44-amino-acid analogue of growth-hormone-releasing hormone (GHRH), structurally based on the full-length GHRH(1-44) with an N-terminal modification that improves protease resistance. It is one of the more thoroughly studied GHRH analogues in both preclinical and clinical research, with a published literature focused on the growth-hormone axis and visceral-adipose-tissue endpoints. The form supplied here is for laboratory research only.
What is Tesamorelin?
Tesamorelin is GHRH(1-44) with a trans-3-hexenoyl group attached to the N-terminus. The N-terminal acyl modification prevents rapid cleavage by dipeptidyl peptidase-4 (DPP-4), extending the molecule's half-life relative to native GHRH. The full sequence is otherwise identical to human GHRH(1-44). It is supplied as a lyophilized white powder for laboratory reconstitution.
Research context
Published research on tesamorelin spans GHRH-receptor pharmacology, growth-hormone pulsatility, IGF-1 axis dynamics, and a body of clinical literature focused on visceral adipose tissue in specific patient populations. Tesamorelin is frequently referenced as a longer, more potent GHRH analogue than CJC-1295 No-DAC (30 amino acids) or Sermorelin (29 amino acids), reflecting its full-length GHRH backbone with stabilizing N-terminal modification. Researchers should evaluate primary sources directly.
How Tesamorelin quality is verified
Every batch of MHS Longevity Tesamorelin is submitted to an independent third-party laboratory before release:
- HPLC separates components and measures the tesamorelin peak as a percentage of total peak area. Anything below 99% is rejected.
- Mass Spectrometry is especially informative for tesamorelin: it confirms both the full 44-residue length (long peptides accumulate truncation errors that HPLC alone may not resolve) and that the trans-3-hexenoyl N-terminal modification was correctly attached. A high-quality MS result documents both.
What a Tesamorelin Certificate of Analysis shows
- Compound name and structural designation. Tesamorelin, with the full 44-amino-acid GHRH(1-44) sequence and the trans-3-hexenoyl N-terminal modification notation.
- Batch identifier. The unique ID linking certificate to vial.
- Test date. When the analysis was performed.
- Method. HPLC, MS, or both, with column and mobile-phase notes.
- Verified purity %. The HPLC result. We require 99%+.
- Lab and signatures. The independent lab performing the analysis.
Storage and handling (research lab context)
Lyophilized Tesamorelin should be stored at -20°C or below for extended stability. Once reconstituted in bacteriostatic water, the solution is typically held at 2–8°C and used within the documented stability window. Long peptides like tesamorelin benefit from minimized freeze–thaw cycling and from single-use aliquoting where possible. Standard aseptic technique applies during reconstitution.

Where to buy Tesamorelin 10mg
The same eight questions apply whether you're buying Tesamorelin 10mgfrom us or anywhere else. Vendors who can't answer any of them are worth a closer look.
Vendor evaluation checklist
1. Is the Certificate of Analysis public and downloadable?
A vendor unwilling to publish HPLC/MS results for the batch you're buying has nothing to verify their purity claim against.
2. Which testing method was used — HPLC, Mass Spectrometry, or both?
HPLC measures purity. Mass Spectrometry confirms the molecule's identity. Reputable batches go through both.
3. What's the verified purity percentage on the published COA?
Industry research standard is 99%+. Below that, you're paying for a compound diluted with synthesis byproducts.
4. Where does the product ship from?
US-based fulfillment generally means shorter handling times, customs-free delivery, and clearer return remedies.
5. Is the price published at a single list rate, or hidden behind tier locks?
Opaque pricing is a yellow flag. Transparent vendors quote the same number to every customer.
6. What's the free-shipping threshold, if any?
Compare the all-in cost (product + shipping + handling) — not just the headline price.
7. How is the product stored prior to shipment?
Lyophilized peptides degrade with temperature swings. Vendors should disclose temperature-controlled storage.
8. Is there a documented damage-claim and return policy?
Discreet shipping carries handling risk. A clear, written policy protects you when something goes wrong.
