Metabolic & Weight Loss

5-amino-1-methylquinolinium, 5-amino-1MQ, 5A1MQ, NNMTi (informal), 5-amino-1-methylquinolin-1-ium

5-Amino-1MQ is a synthetic small-molecule (quinolinium salt) inhibitor of the enzyme nicotinamide N-methyltransferase (NNMT) — it is NOT a peptide, despite being marketed and discussed alongside peptides in the research-chemical community. It is studied only in cell culture and mice as a candidate for obesity and metabolic disease, where NNMT inhibition reduced body weight and fat mass in diet-induced obese mice without changing food intake. It is not an approved medicine anywhere, and there are no published human clinical trials, no human pharmacokinetic data, and no placebo-controlled efficacy studies.

FTPP (Prohibitin-Targeted Proapoptotic Peptide)

Adipotide is included for complete PeptideGuide catalog coverage. Identity, evidence, regulatory status and safety claims are awaiting independent verification.

Acadesine, AICA-riboside, AICAr, 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside, AICA ribonucleoside, 5-amino-4-imidazolecarboxamide riboside

AICAR (acadesine) is an AMPK activator — a cell-permeable nucleoside/adenosine analog, not a peptide and not a SARM, with zero androgen-receptor activity. Its fame rests on a single rodent result — a ~44% endurance gain in sedentary mice (Narkar 2008) — that got it WADA-banned in 2009, while human efficacy for endurance or body composition remains unestablished. It is not an approved medicine for physique or performance: the clinical program ("acadesine") was terminated for futility in cardiac surgery and never reached approval.

Modified GLP-1 Analog

Altglutide is included for complete PeptideGuide catalog coverage. Identity, evidence, regulatory status and safety claims are awaiting independent verification.

LAT8881, LAT-8881, Anti-Obesity Drug 9604, Tyr-hGH(177-191)

AOD-9604 is the synthetic Y-start analog [F176Y]hGH(176-191), later developed as LAT8881. Its pivotal obesity trial did not show significant weight loss versus placebo, and that program ended in 2007. Three later registered pain studies also did not report a statistically significant primary efficacy result.

AM833, NN9838, NNC0174-0833

Cagrilintide is an investigational, long-acting amylin analogue studied alone and as the amylin component of CagriSema. No single-agent FDA or EU approval was identified as of 20 August 2026.

GW0742, GW610742, GW610742X

A synthetic, highly selective small-molecule PPARδ (PPARβ/δ) agonist and a close structural analog of cardarine (GW-501516), differing by a single extra fluorine atom — not a peptide and not a SARM. It exists only as a laboratory research-tool compound: never tested in humans, with no human safety data and no approval for human use anywhere. Not approved by any regulator; preclinical (animal/in-vitro) only.

Somatotropin (176-191), Native human growth hormone fragment 176-191

hGH Fragment 176-191 is the native C-terminal 16-amino-acid sequence of mature human growth hormone.

Rev-ErbA agonist SR9011, REV-ERB agonist SR9011, SR-9011

A synthetic agonist of the Rev-ErbA (REV-ERBα/β) circadian-clock and metabolic nuclear receptors — NOT a SARM and NOT a peptide — and the N-pentyl sister compound of SR9009 (stenabolic) from the same 2012 Scripps discovery program. Its "fat-loss/endurance" reputation rests entirely on rodent and cell studies, it has poor drug-like properties and documented off-target effects, and there are no human trials. Not approved for human use by any regulator; sold only as a research chemical.

SR9009, SR-9009, Stenabolic

A synthetic agonist of the Rev-ErbA (REV-ERBα/β) heme-binding circadian nuclear receptors — NOT a SARM and NOT a peptide — created in an academic lab (Scripps) as a tool compound to probe circadian and metabolic biology. Its "exercise in a bottle" reputation rests on a single 2012 mouse study using injections, and is undercut by essentially no oral bioavailability and documented off-target effects. Not approved for human use by any regulator; sold only as a research chemical.

BI 456906, BI-456906

Survodutide is an investigational, lipid-modified 29-residue peptide that agonizes the glucagon and GLP-1 receptors. Phase 3 trials report weight and MRI-measured liver-fat effects, while biopsy evidence supports MASH improvement without establishing fibrosis reversal.
