About our gh secretagogues range
Growth hormone secretagogues act through two main receptor systems: the GHRH receptor (CJC-1295 with and without DAC, tesamorelin, sermorelin) and the ghrelin receptor GHS-R1a (ipamorelin, GHRP-2, GHRP-6, hexarelin). This category also includes IGF-1 LR3, a widely used cell culture growth factor.
Each page explains where the compound sits in the GH axis and how it compares with its closest relatives, so you can choose the right tool compound for your study design.
Frequently asked questions

How is quality documented?+
Batches are sent to an independent laboratory for HPLC purity analysis and mass spectrometry identity confirmation. Certificates of analysis are published on our Lab Reports page and linked from each product page as they are issued.
How should I store lyophilised peptides?+
For long-term storage keep sealed vials frozen at -20°C, away from light and moisture. For short periods, 2 to 8°C refrigeration is suitable. Lyophilised peptides tolerate room temperature during transit.
Are research peptides legal to buy in the UK?+
Many research peptides are not licensed medicines and may be sold for laboratory research, provided they are not marketed or supplied for human use. The regulatory status of individual substances can change, so buyers are responsible for checking the rules that apply to their own work.
Who can order from Vyrax Labs?+
Orders are accepted from adults aged 18 or over who are buying for legitimate laboratory, analytical or educational research. Every order includes a confirmation that the materials will not be used in humans or animals.
