Buy Ipamorelin UK, Tesamorelin UK and IGF-LR3 UK
Ipamorelin is a selective GHRP (growth hormone releasing peptide) studied for its clean GH-pulse profile without significant cortisol or prolactin influence. Tesamorelin is a GHRH analogue studied extensively in metabolic research. IGF-LR3 is a long-arginine variant of IGF-1 with extended in-vitro half-life.
All three are supplied by Pondok as lyophilised research-grade material with full batch documentation. Every batch is independently HPLC tested with a verified Certificate of Analysis, shipped with fast next-day UK delivery from Pondok Peptides, a trusted UK peptide supplier.
GHRP, GHRH and IGF-1 explained
GHRPs (such as Ipamorelin) act on the ghrelin receptor to trigger GH release. GHRH analogues (such as Tesamorelin) work through the GHRH receptor to extend GH pulse amplitude. IGF-1 variants (such as IGF-LR3) are downstream signalling molecules studied independently from upstream GH triggers.
Pondok stocks one representative compound from each of the three classes so researchers can study the full pathway.
Verification 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 growth hormone 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 cleanest GHRP for laboratory work?+
Ipamorelin is generally considered the most selective GHRP in current literature, with minimal effect on 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 test growth hormone peptides?+
Yes. Every Ipamorelin, Tesamorelin and IGF-LR3 batch is independently HPLC tested. COAs are downloadable from each product page.
