Ipamorelin 5mg

Ipamorelin is a synthetic pentapeptide developed in the 1990s as a growth hormone secretagogue. It contains the non-standard amino acid isobutyric acid and two D amino acids, including D-2-naphthylalanine, and is a growth hormone secretagogue receptor (GHS-R1a) agonist. Among the GHRP family, it is distinguished by its selectivity: it acts on growth hormone release from somatotrophs without the ACTH, cortisol, or prolactin release seen with GHRP-2 and GHRP-6.

Ipamorelin is used in ghrelin receptor pharmacology and pituitary signaling research. Provided as a lyophilized powder, 5 mg per vial.

Documented from receipt to release

Every catalogue item is identified by product, labelled size, and lot or batch. Receiving records preserve the supplier reference, arrival condition, and storage destination. A batch remains distinct in the catalogue so its documentation can be reviewed without relying on a general product claim.

Analytical records

Where a third-party laboratory report is available, the batch record links the reported purity, test date, method, laboratory, and report number to the uploaded certificate. A product-level purity statement is a catalogue specification, while the certificate records the result reported for one batch.

Release and status controls

• Confirm product identity and labelled amount against receiving records.
• Review packaging condition and storage history.
• Associate the analytical report with the correct batch.
• Mark one batch as current and preserve prior records as archived.
• Hold or remove catalogue availability when documentation is incomplete.
