Growth Hormone Research Catalog

Growth hormone secretagogues and GHRH analogues for laboratory research, including CJC-1295 DAC, ipamorelin, tesamorelin and IGF-1 LR3.

Compounds here are studied for their action on growth hormone release or on downstream signaling. They differ in half-life, receptor target and stability, so read each product page rather than treating the category as interchangeable. Confirm reconstitution and storage requirements against your own protocol.

The compounds here reach the growth hormone axis by three different routes, and the distinction matters more than the category name suggests. Tesamorelin is a GHRH analogue stabilised against DPP-4 cleavage; CJC-1295 DAC is a GHRH analogue extended instead by covalent albumin binding; ipamorelin does not touch the GHRH receptor at all and acts at the ghrelin receptor. IGF-1 LR3 sits downstream of all three, at the growth factor rather than the secretagogue end. Study designs frequently pair one GHRH-axis compound with one ghrelin-receptor compound to test whether the two pathways are additive, so read the mechanism line on each product page before treating any two as substitutes.

Handling separates this group more sharply than mechanism does. Tesamorelin, CJC-1295 DAC and ipamorelin are refrigerated at 2-8°C; IGF-LR3 is stored at -20°C and records an explicit instruction to avoid freeze-thaw, which is the one handling constraint in this category that changes how material is aliquoted rather than merely where it is kept. That difference follows from what the molecules are: the three secretagogues are short peptides, while IGF-1 LR3 is a 83-residue protein analogue with tertiary structure to lose. Tesamorelin and CJC-1295 DAC additionally record protection from light. Request the batch documentation for the exact material, and read a purity figure alongside identity and content rather than on its own.

Growth Hormone Research Catalog questions

What is listed under Growth Hormone?

Four listings: CJC-1295 DAC, IGF-LR3, Ipamorelin and Tesamorelin 20mg. Each is grouped here by the research area its published literature addresses, not by any effect. Open a listing to read its description, the sizes offered and the specifications recorded for it.

How are the listings under Growth Hormone stored?

This category spans three storage requirements, so they are not interchangeable on handling: CJC-1295 DAC and Tesamorelin 20mg — refrigerate at 2-8°C, protect from light; IGF-LR3 — store at -20°C, avoid freeze-thaw; Ipamorelin — refrigerate at 2-8°C. Each product page carries its own storage line, and that is the one that governs. How stable is a lyophilised peptide in storage? covers what temperature and residual moisture do to dried material.

Which listings under Growth Hormone need reconstitution?

CJC-1295 DAC, IGF-LR3, Ipamorelin and Tesamorelin 20mg are supplied as lyophilized powder and require a diluent. Bacteriostatic water is stocked separately in 3mL and 10mL vials. Savage Labs does not specify a reconstitution volume, a working concentration, or a basis for calculating either — those are determined by the protocol the material is used in, not by this catalog.

What purity is reported across Growth Hormone?

Reported purity differs by listing: 99.0% for CJC-1295 DAC; 99% for IGF-LR3; 99.2% for Ipamorelin; 99.5% for Tesamorelin 20mg. Each figure is what was reported for that batch. A purity figure is a chromatographic measurement and does not on its own establish identity or how much peptide a vial holds — purity, identity and content are three separate measurements. Ask for the batch documentation covering the material you intend to order.
