Tesamorelin stimulates the GHRH pathway. Human studies in HIV-associated abdominal fat accumulation have measured reduced visceral fat; that specific finding should not be confused with general body-weight loss.
Ipamorelin is investigated for ghrelin-receptor activity, growth-hormone release and gastrointestinal function. These are distinct research areas; the postoperative trial discussed below did not establish its primary recovery benefit.
This long-acting GHRH analogue has been studied for sustained stimulation of growth hormone and IGF-1. The research clarifies endocrine signaling; downstream benefits for recovery or body composition require their own clinical evidence.
This entry concerns GHRH-related signaling without the DAC modification. Understanding the precise molecule matters because published long-acting CJC-1295 results cannot be transferred directly to the non-DAC form.
GHRP-2 helps researchers examine growth-hormone release and appetite signaling. Human experiments show acute hormonal and food-intake effects; these findings are different from demonstrated improvements in muscle or recovery.
GHRP-6 is explored for its effects on the growth-hormone secretagogue pathway. Research helps explain hormone-release mechanisms and their interaction with GHRH; clinical body-composition benefits cannot be inferred from cell studies.
Hexarelin is investigated in growth-hormone and CD36-related pathways. Preclinical work on cholesterol transport offers a mechanistic reason to study cardiovascular biology, without establishing clinical heart protection.
IGF-1 LR3 is explored for growth-factor effects on muscle-cell proliferation and differentiation. Its potential applications concern tissue-growth biology; laboratory responses do not establish safe muscle-building benefits in people.
Kisspeptin-10 is studied as an upstream signal in the reproductive hormone axis. Human work shows stimulation of LH, helping researchers understand reproductive physiology without establishing a general fertility or libido benefit.
MGF-related research examines how muscle responds to mechanical stress and injury. Studies explore IGF-1 variants and cell-growth signals; these findings do not establish that externally administered MGF improves recovery.
PEG-MGF combines an MGF-related peptide concept with PEG modification. Researchers would need matching molecular specifications to evaluate persistence and biological activity; findings for non-PEG peptides are not equivalent.
PT-141, or bremelanotide, has human clinical evidence for specific desire and distress outcomes in women with hypoactive sexual desire disorder. These results concern a defined clinical setting, not a general enhancement effect.
Sermorelin is studied through the GHRH pathway that stimulates growth-hormone release. Human endocrine responses help explain its biology, but are not equivalent to demonstrated rejuvenation or fitness benefits.
