- Growth hormone secretagogues—CJC-1295, ipamorelin, MK-677 (ibutamoren), GHRP-2—stimulate pituitary GH release, which elevates IGF-1 and activates hormone-sensitive lipase (HSL) in adipocytes. The lipolytic effect is real but indirect: GH signals fat cells to release stored triglycerides into circulation, but oxidation of those fatty acids still requires downstream enzymatic activation (CPT1, beta-oxidation enzymes in mitochondria). If NAD+ availability is low—because NNMT is high—the released fatty acids may be re-esterified and stored rather than oxidized.
- 5-Amino-1MQ addresses that bottleneck directly. By blocking NNMT and raising NAD+, it activates AMPK (AMP-activated protein kinase)—the master regulator that shifts cells from anabolic (storage) to catabolic (oxidation) mode. AMPK phosphorylates acetyl-CoA carboxylase (ACC), which reduces malonyl-CoA and disinhibits CPT1, the rate-limiting enzyme for mitochondrial fatty acid uptake. In other words: 5-amino-1MQ ensures that released fatty acids actually get burned.
- Our experience reviewing research protocols shows that growth hormone peptides and 5-amino-1MQ are not redundant—they're complementary. GH secretagogues mobilize fat from storage; 5-amino-1MQ ensures the mobilized fat is oxidized rather than re-stored. The 2021 study found that 5-amino-1MQ increased oxygen consumption (VO2) and energy expenditure without altering food intake or locomotor activity—suggesting the metabolic shift happens at the cellular level, not through behavioral or thermogenic pathways that GH peptides rely on.
