-
Recovery
Tissue and joint repair research using BPC-157, TB-500, and combined stacks. These compounds are widely studied in pre-clinical models for their role in musculoskeletal healing and recovery timelines.
-
GH / Anti-Ageing
Growth hormone research covering Ipamorelin, CJC-1295, and Tesamorelin. Commonly used in studies looking at GH secretion pathways, body composition, and age-related decline in hormone output.
-
Weight Management
Metabolic and body composition research with AOD-9604 and Retatrutide. Both compounds are studied for their effects on adipose tissue regulation and appetite-related signalling pathways.
-
Longevity
Cellular health and ageing research using GHK-Cu, NAD+, and MOTS-C. These peptides feature heavily in studies on mitochondrial function, cellular senescence, and long-term tissue maintenance.
-
Nootropics
Cognitive and neurological research with Semax and Selank. Both are studied for their effects on BDNF expression, stress response, and short-term cognitive performance in research models.
-
Sleep & Recovery
Sleep cycle and restorative research centred on DSIP. Studied for its role in regulating sleep-wake patterns and supporting recovery-focused research protocols.
