This category covers compounds used to study the growth hormone axis and wider endocrine signalling: GHRH and ghrelin (GHS-R1a) receptor activity, pulsatile growth hormone release, IGF-1 receptor signalling and the hypothalamic control of pituitary hormones, in cell-based assays and animal models.

The range includes the GHRH analogues CJC-1295, CJC-1295 DAC and Tesamorelin; Ipamorelin, a selective ghrelin-receptor agonist; IGF1-LR3, a long-acting IGF-1 analogue widely used in cell-culture work; AOD9604, a modified fragment of the growth hormone C-terminus; and Kisspeptin 10, studied for its role upstream of the reproductive hormone axis.

Where a batch has been tested, its certificate of analysis is published in our lab reports with the batch number, test date and method. All products are supplied for in-vitro laboratory research only and are not for human or veterinary use.
