Retatrutide vs Sermorelin (GRF 1-29): research peptide comparison (UK)
Retatrutide 30 mg compared with Sermorelin (GRF 1-29) 5 mg for UK laboratory supply: identity, documentation, storage, and how Solent lists both. Research use only.
Two defined materials
Retatrutide and Sermorelin (GRF 1-29) are separate catalogue entries. A synthetic lipidated peptide studied as a triple agonist of the GLP-1, GIP and glucagon receptors in experimental models. A synthetic analogue of the first 29 amino acids of growth-hormone-releasing hormone (GHRH 1–29), studied in research into GHRH-receptor signalling and the GH axis in experimental models. Neither is a licensed medicine. Solent does not recommend one over the other for any biological effect — choose by the protocol you have written.
Retatrutide
Retatrutide 30 mg is listed under metabolic. CAS 2381089-83-2. Purity ≥ 99% (HPLC). Packed as lyophilised powder and dispatched from Southampton.
Sermorelin (GRF 1-29)
Sermorelin (GRF 1-29) 5 mg is listed under gh axis. CAS 86168-78-7. Purity ≥ 99% (HPLC). Same standard: HPLC identity, lot number on the vial.
Buying both in the UK
UK laboratories can order Retatrutide and Sermorelin (GRF 1-29) on the same research invoice from the cheapest HPLC ≥99% Southampton catalogue we record. Next-working-day courier to most mainland postcodes. Confirm research-use-only at checkout.
