Growth Hormone Secretagogue Research Peptides
These compounds fall into two mechanistic families: GHRH analogs that act on the GHRH receptor, and ghrelin-receptor (GHS-R1a) agonists. Research interest lies in their differing selectivity profiles and effects on pulsatile secretion in animal models.

Direct comparisons in this area
Shortlisting within a research area is where most of these decisions actually get made, so the pairs are compared on the same measured figures rather than on claims.
Ipamorelin vs CJC-1295 (no DAC)
Ghrelin receptor agonism versus GHRH receptor agonism — different receptors, frequently studied together for that reason.
CJC-1295 (no DAC) vs Tesamorelin
Truncated GHRH(1-29) against full-length GHRH(1-44). Sequence length is the whole distinction and it is routinely glossed over.
IGF-1 LR3 vs Tesamorelin
Direct IGF-1 receptor agonism versus upstream GHRH stimulation — acting at opposite ends of the same axis.

IGF-1 LR3 vs Ipamorelin
