Buy Tesamorelin UK
Research-grade Tesamorelin 10mg — ≥99% HPLC purity, Janoshik independently verified, shipped same-day from our UK warehouse.
What It Actually Is
Tesamorelin is a synthetic version of growth hormone-releasing hormone (GHRH) — the signal your pituitary normally listens for before releasing growth hormone.
The clever part is in the chemistry. Native GHRH falls apart quickly in the body, so tesamorelin carries a small modification on one end of the molecule that makes it far more stable while keeping the same shape the GHRH receptor recognises. The result is a peptide that does the same job as the natural signal, but lasts long enough to actually be studied. It was developed by Theratechnologies and sits in the same broad family as sermorelin and CJC-1295.
We supply it as a lyophilised research compound, ≥99% purity, made under controlled conditions. The current UK-warehoused batch tests at 99.120% by HPLC.
Why It Gets So Much Research Attention
The first GHRH analogue to actually get approved
Most research peptides live their whole lives in the lab. Tesamorelin is one of the rare exceptions. In 2010 it became the first — and to date only — GHRH analogue to win full FDA approval, marketed as Egrifta and indicated to reduce excess visceral abdominal fat in a specific patient population.
That visceral-fat finding is the headline. In the published trials, tesamorelin lowered visceral adipose tissue (the deep belly fat wrapped around the organs) by a meaningful margin over roughly six months — without the blunt-instrument approach of injecting growth hormone directly.
The mechanism is what makes researchers lean in: rather than flooding the system with external growth hormone, tesamorelin nudges the pituitary to release its own in natural pulses, which then raises IGF-1. Because the body’s own feedback loop stays intact, it behaves very differently from exogenous GH. That’s also why it’s since been explored in research well beyond its original approval — liver fat and non-alcoholic fatty liver disease, lipid markers, and cognition among them.
The above describes the published clinical and regulatory record for context only. Momentum Peptides supplies tesamorelin strictly for in-vitro laboratory research — nothing here is guidance for human use.
How It Compares
Tesamorelin vs the other GHRH peptides
| Compound | What it is | Why researchers use it |
|---|---|---|
| Tesamorelin | Stabilised full-length GHRH(1–44) | The clinically-validated GHRH analogue; visceral fat & GH-axis research |
| CJC-1295 | GHRH analogue (±DAC) | Extended half-life; usually paired with a GHRP |
| Sermorelin | GHRH(1–29) fragment | Shorter-acting GHRH reference compound |
| Ipamorelin | GHRP / ghrelin-receptor agonist | Different receptor entirely — often studied alongside a GHRH peptide |

Handling & Storage
Reconstitute with sterile bacteriostatic water and swirl gently rather than shaking. Store the lyophilised vial cool, dry and away from light, where it’s stable for up to two years; keep reconstituted solution refrigerated at 2–8°C and don’t put it through repeated freeze–thaw cycles. Handle in a controlled lab environment using standard aseptic technique.
Common Questions
- Where can I buy Tesamorelin in the UK?
- We hold Tesamorelin 10mg in our UK warehouse and dispatch same-day with 24-hour tracked delivery. Every batch is ≥99% HPLC purity and independently checked by Janoshik Analytical — the current batch (MP-TES10-0426) came back at 99.120%, and the certificate is on the product page if you want to read it yourself.
- What makes Tesamorelin interesting to researchers?
- It’s the first — and so far only — GHRH analogue to earn full FDA approval. That clinical track record is unusual for a peptide of this kind, which is exactly why it turns up so often in the published research on the growth-hormone axis and visceral fat.
- What was Tesamorelin originally approved for?
- In the clinical literature, tesamorelin is the active ingredient in a prescription medicine (Egrifta) approved by the US FDA in 2010 to reduce excess visceral abdominal fat in a specific patient group. We supply it strictly as a research compound — this is background on the published record, not guidance for use.
- How is Tesamorelin different from CJC-1295?
- Both are GHRH analogues, but tesamorelin is a stabilised full-length GHRH(1–44) molecule with a long clinical research history, whereas CJC-1295 is typically studied for its extended half-life and is often paired with a GHRP like Ipamorelin. Different tools, different research questions.
- How should Tesamorelin be stored?
- Keep the lyophilised vial cool, dry and out of direct light — it’s stable that way for up to 24 months. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and avoid repeated freeze–thaw cycles.
