Growth Hormone & Muscle Research Peptides
Nothing in this category has a third-party purity result yet. That’s the first thing worth knowing, and we’d rather put it here than let you find it product by product.
Four compounds sit here across three different mechanism classes, and one of them isn’t a peptide analogue at all. Only Ipamorelin can be bought today.
Nothing here is approved for human use in Canada. We publish no dosing, no protocols and no stacks.
What's here, what it targets, and what has been tested
| Compound | Class and target | Purity | Available now |
|---|---|---|---|
| Ipamorelin | Selective secretagogue, ghrelin receptor. CAS 170851-70-4, 711.9 g/mol | Not tested | In stock, 2mg, 5mg, 10mg |
| CJC-1295 (no DAC) | GHRH analogue, also called Modified GRF 1-29. CAS 863288-34-0, 3,367.97 Da | Not tested | Out of stock, 5mg and 10mg |
| Tesamorelin | GHRH analogue. CAS 218949-48-5, 5,136 g/mol | Not tested | Out of stock, 2mg to 20mg |
| HGH (Somatropin) | Recombinant human growth hormone, not an analogue. Supplied in IU, not mg | Not tested | No price, cannot be ordered |
Four blanks in the purity column, and we're not going to fill them with a manufacturer's own claim dressed up as independent. Where we have a certificate elsewhere on the site, it names the laboratory and the batch. Here we have none.
The nearest certificate is in another category. The CJC-1295 without DAC plus Ipamorelin blend carries a Medutest certificate reporting 99.27%, and it sits in peptide blends and stacks. Read that page before you weigh the figure: the certificate's identity data describes CJC-1295 alone rather than the blend, which is a limitation we have raised with the laboratory.
Three mechanism classes, and one of these is not a peptide analogue
The category name flattens three genuinely different things.
Secretagogues act at the ghrelin receptor. Ipamorelin is the one here, described in the literature as a selective growth hormone secretagogue and studied in a rodent gastric dysmotility model.1
GHRH analogues act at a different receptor entirely. CJC-1295 without DAC and Tesamorelin are both in this class.2 Tesamorelin has been studied in a randomised placebo-controlled trial in patients with type 2 diabetes, which examined safety and metabolic effects.3 That trial tested a pharmaceutical preparation in a supervised clinical setting, not a research vial.
HGH is neither. Somatropin is recombinant human growth hormone itself, the protein rather than a compound that acts on the systems producing it. That's why it's supplied in international units instead of milligrams, and it's the reason it doesn't belong in the same comparison as the other three.
That distinction is also why the ghrelin-receptor and GHRH-receptor compounds get paired in research: they act on different receptors, so they aren't alternatives to each other.
CJC-1295 without DAC is not sermorelin, and not CJC-1295 with DAC
Three molecules, overlapping names, easy to confuse. The no-DAC form is also called Modified GRF 1-29 and carries CAS 863288-34-0 at 3,367.97 Da. Sermorelin's CAS is 86168-78-7. The DAC version has a molecular weight of 3,647.2. If a listing prints sermorelin's identity data on a CJC-1295 page, that tells you how carefully the rest of it was written.
Regulatory status in Canada
Health Canada regulates injectable peptides as drugs and has stated in writing that labelling one "for research use only" doesn't remove it from that regulation.4 Every compound on this page is supplied for laboratory research use only, and nothing here is approved for human or veterinary use.
HGH carries the most exposure of anything in this category. Human growth hormone appears by name on the seized-product list in Health Canada's notice,5 and licensed somatropin products exist as prescription medicines. Research-grade material of the same protein is not those products, and clinical evidence for them does not transfer to a vial bought online.
Buying growth hormone peptides in Canada
Only Ipamorelin can be ordered today, in 2mg, 5mg and 10mg. CJC-1295 (no DAC) and Tesamorelin are listed but out of stock, and HGH has no price set, so it cannot be bought at all regardless of what its stock label says. Each product page shows its own current state, which is more reliable than this one.
Everything ships as lyophilised powder and needs bacteriostatic water, which we stock separately. Compare on price per milligram rather than price per vial, except for HGH, where international units and milligrams are not the same unit and cannot be compared directly.

Common questions
What are growth hormone peptides? A loose grouping for compounds that interact with the growth hormone axis. Here that means one ghrelin-receptor secretagogue, two GHRH analogues, and recombinant growth hormone itself. They aren't interchangeable and they don't act on the same receptor.
Which of these has a certificate of analysis? None of the four. The closest is the CJC-1295 without DAC plus Ipamorelin blend at 99.27%, which is a different product in a different category.
Why is HGH sold in IU rather than mg? Because somatropin is the recombinant protein itself and is conventionally measured in international units. That also means its price cannot be compared per milligram against the other three.
Can I buy HGH? Not at present. It has no price set. It's also the compound in this category with the greatest regulatory exposure.
What's the difference between a secretagogue and a GHRH analogue? The receptor. Secretagogues act at the ghrelin receptor, GHRH analogues at the growth hormone releasing hormone receptor. That difference is why the two classes get studied together rather than as substitutes.
Are they safe? No safety profile has been established for any of these as supplied here, and none has a purity assay either, so there is less information behind this category than any other on the site. We'd rather say that than imply otherwise.
Are they legal in Canada? Health Canada regulates injectable peptides as drugs, and research use labelling doesn't change that. Nothing here is approved for use in a person, we won't supply dosing, and buying a vial doesn't make its use lawful.
How long does reconstituted material last? Much less time than sealed lyophilised powder. Reconstitution shortens the usable life considerably, which is why the vials ship as dry powder.
