Growth Hormone Peptides

Our growth hormone peptides cover both sides of the GH axis: GHRH analogues like sermorelin and tesamorelin, ghrelin receptor agonists like ipamorelin, plus IGF-1 LR3 and the fragment AOD-9604. All come as lyophilized vials.

What are growth hormone peptides?

Growth hormone release is controlled from two directions. GHRH (growth hormone-releasing hormone) tells the pituitary to release it, and ghrelin acting on the GHS-R receptor gives a second push. Research peptides exist for both pathways, which is why they’re so often paired.

Sermorelin is the first 29 amino acids of GHRH, tesamorelin is a stabilized full-length version, and CJC-1295 (no DAC) is a modified short form. On the ghrelin side, ipamorelin is the most selective option. Further down the chain, IGF-1 LR3 is a long-lasting version of the growth factor that GH triggers, and AOD-9604 is a fragment of GH itself.

How to choose growth hormone peptides

If you’re studying the GHRH receptor, choose sermorelin, tesamorelin or CJC-1295. For the ghrelin receptor, ipamorelin is the cleanest tool. To study both at once, the CJC-1295 and Ipamorelin blend puts them in one vial.

IGF-1 LR3 suits cell culture and receptor signaling work. AOD-9604 is the choice for fat metabolism and cartilage models, since it doesn’t act like full growth hormone.

Formats and prices at a glance

This range has 6 products: five lyophilized vials and one blend. Prices run from $49.99 to $74.99. Every product page lists the exact amount, the format and the SKU, so you can compare like for like before you order.

Quality, testing and storage

Most of our vials carry a QR code on the label that opens the certificate of analysis for that exact batch. Check the lot number on the COA against the vial before you open it, and keep a copy with your notes.

Store lyophilized vials in the fridge, or the freezer for long periods, and let them reach room temperature before opening. Sprays go in the fridge once opened. Capsules and lotions keep on a cool, dry shelf.

Pulses, half-life and pairing

Natural growth hormone is released in pulses, and much of the research on these peptides is about copying that pattern. Short-acting peptides like sermorelin and CJC-1295 (no DAC) give brief pulses. Tesamorelin is stabilized to last longer, and IGF-1 LR3 lasts for hours.

Pairing a GHRH analogue with a ghrelin receptor agonist is common because the two pathways add together. That’s the reasoning behind our CJC-1295 and Ipamorelin blend.

Growth hormone peptides FAQ

What’s the difference between GHRH analogues and GHRPs?

GHRH analogues act on the GHRH receptor, and GHRPs like ipamorelin act on the ghrelin receptor. Both lead to growth hormone release.

Does IGF-1 LR3 need a special solvent?

It often dissolves better with a little acetic acid. We sell it in 10ml vials.

Do you sell a CJC-1295 and Ipamorelin blend?

Yes, 5mg of each in one vial.

Are growth hormone peptides for human use?

No. They’re sold for laboratory research only.
