Growth hormone secretagogue receptor (GHSR) agonists like GHRP-2 are well known for their ability to produce large spikes in GHlevels. These spikes, while providing a number of interesting and important benefits in animal models, are also shortlived because thehalf life of most GHSR agonists is relatively short, To achieve long-term GH level increases, it is possible to use a GHRH analogue likemodified GRF. This provides a long-term increase in both basal and peak GH levels, but nowhere near the kind of GH spike that aGHSR agonists provides. in addition, animal models show that GHRH analogues are susceptible to somatostatin interference, whichcan offset increases in GH levels.
To get the best of both worlds, research into combining GHSR agonists and GHRH analogues is being undertaken. One particularhresearched combination is modified GRF with GHRP-2[4]. The synergy provides increased basal and peak levels of GH as wel asmeasured spikes that boost the benefits of both peptides in ways that simply increasing one or the other cannot
The net result of combining these peptides is improved GH release and substantial shifts in metabolism away from fat deposition.Lean body mass is increased substantially, insulin levels fall, and blood sugar becomes more requlatedl2i-4. There is even evidenceto show that both peptides, but particularly ipamorelin, can help to improve bone mineral density and bone healths.
