At Puffin Peptides, our research peptides are sourced from Canada’s largest premium peptide manufacturer, then packaged and shipped here in Canada. Keeping production close to home gives us greater oversight of quality, consistency, packaging, and every batch that leaves our facility.
Working with an established Canadian manufacturer gives us clearer control from sourcing through fulfilment. The result is a more transparent, dependable source for high-quality research peptides, backed by batch documentation and responsive local support.
From sourcing to delivery, our focus is simple: premium Canadian research products, reliable service, and a standard of quality researchers can trust.
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 use.
Most vials are prepared using 2 mL bacteriostatic water unless otherwise noted.
Slowly add the water down the inside wall of the vial and gently swirl until dissolved.

Tesamorelin is a stabilized GHRH analogue studied in pituitary growth-hormone release and downstream IGF signalling. Tesamorelin is selected when a stabilized GHRH analogue fits the study better than a shorter native fragment.
Researchers may compare tesamorelin with sermorelin or modified GRF to study how stabilization changes GHRH-pathway exposure. They may also measure GH pulses and downstream IGF-1 separately from visceral-fat or other longer-term endpoints. They may also keep HIV-lipodystrophy trial evidence separate from general obesity, anti-aging, or performance claims.
Tesamorelin activates the GHRH receptor upstream of endogenous growth-hormone release. A trans-3-hexenoic-acid modification improves resistance to enzymatic breakdown. In plain language, it extends a GHRH-like signal rather than supplying HGH directly. FDA-approved Egrifta products are indicated to reduce excess abdominal fat in adults with HIV and lipodystrophy. They are not indicated for general weight loss. This research vial is not Egrifta and is not a prescription or clinically equivalent product.
Visceral-fat reduction was shown in HIV lipodystrophy trials. Randomized studies of the regulated tesamorelin product demonstrated changes in visceral adipose tissue in adults with HIV-associated lipodystrophy. The population and indication are essential context. Read a pivotal peer-reviewed trial. Approved does not mean general weight loss. The approved label is narrow and explicitly distinct from routine obesity management. Product pages should preserve that distinction rather than generalizing the result. Review the FDA application record. Upstream GHRH is not direct HGH. Tesamorelin depends on pituitary responsiveness and endogenous release. Somatropin activates growth-hormone receptors after direct exposure.

BPC-157 arrived clean and well protected. The 10 mg label was easy to read, and I found the batch details without having to hunt for them.
Quick update on the Tirzepatide: ordering was simple, tracking appeared after the first scan, and everything in the mailer looked tidy.
This was my first time ordering Semaglutide. The strength options were clear and the storage notes were right where I expected them to be.
Short and sweet—Retatrutide was well packed, clearly labelled and exactly as listed.
I took a minute to compare the TB-500 options before choosing 10 mg. The page made that easy, and the parcel arrived in good condition.
Product, documentation, shipping and support answers—without making you hunt through the site.
Yes. Puffin Peptides sources its research peptides from Canada’s largest premium peptide manufacturer, then labels, packages, and ships them from Canada. Product and batch information remains tied to each vial.
No. All Puffin Peptides products are supplied strictly for laboratory research and analytical use. They are not for human or veterinary consumption and are not represented as medicines, treatments, supplements, or substitutes for approved products.
Yes. Batch-specific documentation is published for the applicable product strength and lot when available. Open Batch details on the product page; if a document has not yet been published, contact support with the product name, strength, and lot number.
A lyophilized peptide is a peptide that has been freeze-dried into a powder by removing water under controlled low-temperature and vacuum conditions. This format supports stability during storage and allows the material to be prepared according to the product label and research protocol.
Always follow the storage instructions for the exact product and lot. Unless otherwise stated, keep unprepared lyophilized vials cool and dry, away from heat, moisture, and direct sunlight. Refrigerate prepared vials at 2–8°C and avoid repeated freeze-thaw cycles.
No. The correct diluent, volume, and preparation method can vary by product. Most Puffin lyophilized vials use 2 mL of bacteriostatic water unless the product page or vial label says otherwise. Add liquid slowly down the inside wall, gently swirl, and never shake the vial.
Select the vial strength, enter the planned water volume, and add a target amount if you want a measurement-volume result. The calculator displays the resulting concentration and measurement for laboratory planning only. Confirm the vial label and research protocol before preparation.
