Research use only (RUO); not for human consumption, veterinary use, food, cosmetic, or in vivo application.\u003c\/p\u003e\n\u003cp\u003eIGF-1 LR3 is a recombinant analog of insulin-like growth factor 1 that binds the IGF-1 receptor. An added N-terminal extension and a single substitution are the modifications reported to lower its affinity for the binding proteins that normally sequester native IGF-1. Supplied as a lyophilised powder in a sealed 1 mg vial for laboratory use.\u003c\/p\u003e\n\u003cp\u003eGHRH analogs (tesamorelin, sermorelin, CJC-1295) and GHRPs \/ growth-hormone secretagogues (ipamorelin, hexarelin) act on distinct receptors upstream of the somatotropic axis. They are structurally and pharmacologically separate classes despite frequent co-study.\u003c\/p\u003e\u003c\/section\u003e\u003csection class=\"tc-facts-strip\" style=\"margin:24px 0;padding:16px;border:1px solid #e5e5e5;border-radius:8px;background:#fafafa;\"\u003e\u003ch3 style=\"margin:0 0 12px;font-size:16px;\"\u003eBatch-linked analytical facts\u003c\/h3\u003e\n\u003ctable style=\"border-collapse:collapse;margin:0 0 8px;font-size:15px;\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eAnalytical lab\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003eFreedom Diagnostics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eAssay purity\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e99.14%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eIdentity method\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003eLC-MS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eAssay method\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003eFull panel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eBatch\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e2606120650\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eLot\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e140-01-DK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:6px 12px 6px 0;font-weight:600;\"\u003eTest date\u003c\/th\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e2026-06-15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin:12px 0 0;\"\u003e\u003cstrong\u003eIdentity attested:\u003c\/strong\u003e batch identity confirmed by mass-spec against the linked certificate of analysis — see the linked COA for the analyte and method.\u003c\/p\u003e\n\u003cp style=\"margin:12px 0 0;font-size:13px;color:#555;\"\u003eValues above are derived from our reading of the accredited-lab Certificate of Analysis for this batch; the linked lab-issued PDF governs.
