What is a peptide, actually?

Think of amino acids as Lego bricks. A peptide is just a short chain of them snapped together. Your body makes thousands — insulin is one you've probably heard of. Scientists can also build them in a lab, tweaking the chain so it lasts longer or hits a specific target. The vials on this site contain those lab-made chains as a freeze-dried powder.

So what do the weight-loss ones do?

After you eat, your gut releases hormones that tell your brain "we're full now." The compounds here are engineered copies of those hormones, modified to keep working for a week instead of a few minutes. There are three families on this site:

1. GLP-1s — the originals. Semaglutide is the active ingredient in Ozempic and Wegovy; tirzepatide is the one in Mounjaro and Zepbound. They're approved medicines with enormous trial programs behind them.

2. Dual and triple agonists — newer molecules that pull two or three levers at once (appetite plus calorie burn, for example). Most are still experimental, in late-stage human trials.

3. Amylin analogues — a different fullness signal, separate from the GLP-1 pathway. Also experimental.

What does "research use only" mean?

It means exactly what it says: these are laboratory chemicals for research. They are not medicines, not for human consumption, and we don't give medical advice. Every page on this site says it, because it matters.

How ordering works

1. Pick a compound. Each card tells you in one plain sentence what it is. The compare page lines all ten up side by side.

2. Choose a size and quantity. Prices are per vial in Canadian dollars. Buying more vials at once earns an automatic discount — 5% off two, up to 15% off five. No coupon codes, it's automatic.

3. Check out. Just your shipping details — no account needed. You'll get an order number instantly.

4. Pay by Interac e-Transfer. Send the total to orders@tnpsupply.ca with your order number in the note. Your package ships from Ontario as soon as payment lands, and arrives in 2–5 business days with tracking.

Words you'll see on this site

Lyophilized

Freeze-dried into a powder. It's how the compounds stay stable in the vial — a puff of white powder at the bottom.

Reconstitution

Dissolving that powder in sterile water before lab use. We can do it for you ($12/vial) or you can order the sterile water and do it in your own lab.

Vial

The little glass bottle. One vial = one unit of the listed size (e.g. one 10 mg vial).

HPLC

The lab test that measures purity. Our standard: 98% or higher, verified by an independent lab.

COA

Certificate of Analysis — the lab report proving what's in the vial. Every batch has one; ask us and we'll send it.

Batch

One production run. We match every COA to its batch number, so the report you see is for the vial you get.

Investigational

Still in human trials — not an approved medicine. We always say so plainly on the product page.

Agonist

A molecule that switches a receptor on — the opposite of a blocker. A "GLP-1 receptor agonist" activates the GLP-1 receptor, mimicking the body's own fullness signal.
