At Puffin Peptides, we work with an established Canadian manufacturer and handle packaging and fulfilment here in Canada. Keeping the process close to home gives us better visibility into quality, consistency, packaging, and the batches moving through our catalogue.
That means clearer product information, accessible batch documentation, responsive local support, and a more dependable ordering experience from checkout to delivery.
Our focus is simple: well-made research products, straightforward information, and reliable Canadian service.
Target stubborn visceral fat with precision. Tesamorelin is a growth-hormone-releasing peptide designed to stimulate the body’s natural hormone production, supporting fat metabolism, lean tissue, recovery, and improved body composition—especially around the midsection.
TESAMORELIN is supplied as 5 mg of lyophilized powder in a sealed glass vial for laboratory research. Confirm the selected vial and batch details before preparation.
Tesamorelin is a stabilized synthetic analogue of growth-hormone-releasing hormone designed to activate GHRH signalling and stimulate endogenous growth-hormone secretion.
This 5 mg vial opens with 0.5 mL BAC water.
The default easy rule is 1 mg = 10 units on a U-100 syringe. Changing the water amount updates that relationship automatically.

A clear, quick look at what TESAMORELIN is, how it works, and why it is being studied.
Tesamorelin is best known for visceral abdominal fat, body composition, and growth-hormone release. It attracts people focused on the deeper belly fat that sits around internal organs.
Tesamorelin is a growth-hormone-releasing hormone analogue with human randomized-trial evidence for reducing visceral adipose tissue in people with HIV-associated abdominal fat accumulation. Evidence from that defined population should not automatically be generalized to all forms of obesity or body composition. [1–2]
It is the fat packed deeper inside the abdomen around the organs, not just the softer layer you can pinch. That deeper location is why it matters for more than appearance.
Visceral adipose tissue is fat stored within the abdominal cavity around internal organs, distinct from subcutaneous fat under the skin. It is measured more accurately with imaging than by appearance alone. [1–2]
Its strongest clinical connection is reducing excess visceral abdominal fat in a specific approved population. That is why it stands apart from general ‘lose weight everywhere’ products.
Randomized trials in HIV-associated abdominal adiposity found significant reductions in visceral adipose tissue, which is why tesamorelin has a more specific visceral-fat evidence base than general “fat-loss” compounds. [1–2]
No. Appetite control is not its main story. It encourages growth-hormone release, connecting it more directly to fat metabolism and body composition than hunger.
Tesamorelin acts through GHRH receptors to stimulate endogenous growth-hormone secretion and increase IGF-1; appetite suppression is not its primary established mechanism. [1–2]
Its reputation is specifically about deeper visceral fat, so it should not be described as a guaranteed spot-treatment for every kind of belly fat.
The strongest clinical evidence concerns visceral rather than subcutaneous abdominal fat. It should not be described as a guaranteed spot-reduction treatment for superficial fat. [1–2]
Semaglutide mainly helps control hunger and fullness. Tesamorelin works through growth-hormone signaling and is especially associated with deeper abdominal fat.
Tesamorelin stimulates the GH/IGF-1 axis and has specific visceral-fat evidence in an HIV-associated population; semaglutide is a GLP-1 receptor agonist with a much broader obesity/diabetes clinical program centred on appetite and metabolic regulation. [1–2]
Both encourage growth-hormone release, but Tesamorelin has a much more specific connection to visceral abdominal fat. Ipamorelin is discussed more broadly around recovery, sleep, and body composition.
Both can stimulate endogenous GH release, but tesamorelin is a GHRH analogue with substantial human clinical data in a defined visceral-adiposity indication; ipamorelin is a ghrelin-receptor/GH-secretagogue agonist with a much smaller clinical evidence base. [1–2]
Because stubborn belly fat is frustrating, and visceral fat is difficult to understand from the mirror alone. Tesamorelin gives that specific problem a more focused research story.
The interest is supported by actual randomized human data on visceral adipose tissue, not just mechanism. The key limitation is population specificity: the strongest trials were not general weight-loss studies in otherwise healthy adults. [1–2]

Nice site and helpful chat bot. I’ll be back again.
I can’t believe it but I’ve lost 30lb. It’s been 3 months and felt compelled to write a review. I know it’s not Puffin I have to thank but their site came up in google and brought me here. Thank youuuuuu! <3

Hi! I’m Ask Puffin. I can explain peptides in plain language and help with products, prices, stock, shipping, and site questions. What can I help with?
