Tesamorelin

Tesamorelin, is a syntheitic peptide consiting of 44 amino acids. It is a growth-hormone-releasing hormone (GHRH) analogue researched for the treatment of HIV-associated lipodystrophy (dysfunctional, toxic fat deposition). It is also being researched for its ability to improve peripheral nerve health, slow the progression of mild cognitive impairment, and the reduction visceral fat. This peptide has been found to reduce adiposity by nearly 20% in this population [1]. Research suggests that tesamorelin is approximately 4 times more effective in reducing adiposity than all of the other available therapies combined [2].

Tesamorelin is a lab-made version of the body’s own GHRH signal. In plain terms, it’s designed to nudge the pituitary to release growth hormone in a natural, pulse-like manner, which then influences downstream IGF-1 and a range of metabolic readouts. That “signal-first” approach is why Tesamorelin shows up so often in metabolic and body-composition research.

In research settings, Tesamorelin is discussed around visceral fat (VAT) outcomes, liver and lipid markers, and glucose control after meals. Teams study questions like: how does a GHRH analogue affect fat distribution vs. total weight, what happens to triglycerides and liver enzymes, and how do insulin and IGF-1 move over time? There’s also interest in peripheral nerve health and mild cognitive impairment models—areas where researchers watch for changes in nerve-related measures and cognitive testing. These are research findings, not medical claims, and results depend on model, dose, and protocol.

What makes our Tesamorelin stand out is clean, verified quality. Each batch is identity-confirmed (e.g., mass spectrometry) and purity-checked by HPLC with ≥99% purity (typical). You receive a lot-specific Certificate of Analysis (COA) showing the real test data—proof on paper, not promises.

Consistency matters for reliable comparisons. We keep the same specification and analytical “fingerprint” from batch to batch and track every lot number, so when you reorder you can match the profile you liked and reduce variability in follow-ups and method development.

If you value clarity, documentation, and high purity, Tesamorelin from AI Peptides gives you exactly that—well-characterized material with transparent proof, ready for rigorous lab work.

Not for human or veterinary use. Made in USA

This product is intended as a research chemical only. Not for human use. Peptides will arrive in a lyophilized (powder) form for maximum stability.

Storage Instructions:

All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.

Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.

Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.

However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
