Ipamorelin, Tesamorelin and IGF-LR3 reference material
Ipamorelin is a selective GHRP reference peptide studied for receptor signalling at the ghrelin receptor in vitro. Tesamorelin is a GHRH analogue widely referenced in endocrine signalling research. IGF-LR3 is a long-arginine variant of IGF-1 with extended in-vitro half-life used as a reference compound.
All three are supplied by Pondok as lyophilised research-grade material with full batch documentation. Every batch is independently HPLC characterised with a verified Certificate of Analysis, supplied for in-vitro laboratory research only by Pondok Peptides, a UK research peptide supplier.
GHRP, GHRH and IGF-1 receptor signalling overview
GHRPs (such as Ipamorelin) are referenced as ghrelin receptor research peptides. GHRH analogues (such as Tesamorelin) are referenced as GHRH receptor research peptides. IGF-1 variants (such as IGF-LR3) are downstream signalling reference molecules studied independently in vitro.
Pondok stocks one representative compound from each of the three classes so researchers can study the full endocrine signalling pathway.
Analytical characterisation and purity
Each Ipamorelin, Tesamorelin and IGF-LR3 batch ships with a Certificate of Analysis confirming identity and HPLC purity. Lyophilised under controlled conditions and stored cold from synthesis to dispatch.
Storage
Store lyophilised endocrine research peptides at minus 20 degrees Celsius long term. IGF-LR3 in particular benefits from minimised freeze-thaw exposure. After reconstitution, refrigerate at 2 to 8 degrees Celsius and use within 28 days.
Frequently Asked Questions
What is the most selective GHRP reference peptide in current literature?+
Ipamorelin is generally referenced as the most selective GHRP in current literature, with minimal cross-activity in receptor signalling studies at the cortisol or prolactin pathways.
What is the difference between IGF-1 and IGF-LR3?+
IGF-LR3 is a long-arginine analogue of IGF-1 with an extended half-life in vitro and reduced binding to IGF binding proteins.
Is Tesamorelin a GHRH or a GHRP?+
Tesamorelin is a GHRH (growth hormone releasing hormone) analogue, not a GHRP. They act on different receptors.
Do you third-party characterise endocrine research peptides?+
Yes. Every Ipamorelin, Tesamorelin and IGF-LR3 batch is independently HPLC characterised. COAs are downloadable from each product page.
