5-amino-1MQ side effects and risks

An experimental NNMT blocker with animal findings, no human dosing trials and uncertain risks.

Also called: 5-Amino-1MQ, 5-amino-1-methylquinolinium, 5A1MQ, 5-AMQ, 5A-1MQ, 5-amino-1-methylquinolinium iodide, 5-amino-1-methylquinolinium chloride.

NNMT inhibitors · Small-molecule nicotinamide N-methyltransferase inhibitor · Evidence: Animal studies only.

Reported side effects

  • Stomach upset or nausea: Community reports; no controlled human rate., moderate. Stop and seek review if symptoms persist. (source)
  • Injection stinging or skin bumps: Anecdotal reports; no measured rate., mild. Persistent redness, warmth or swelling needs assessment. (source)
  • Dull or blunted emotions: One oral use report, more noticeable with higher doses., moderate. Stop and discuss new mood changes with a clinician. (source)
  • Sleepiness: Reported in oral users and after 3 mg subcutaneous; frequency unknown., moderate. Avoid driving when sleepy and review new symptoms. (source)
  • Frequent urination: One oral 50 mg report; identity and cause were unconfirmed., moderate. New persistent thirst or urination needs medical review. (source)
  • Illness after mixed injections: One teaching case; compound specific causation and rates are unknown., serious. Seek urgent care for systemic illness or dark/low urine. (source)

Stop and get help if

  • Dark urine or much less urine, especially with vomiting or muscle pain: Stop use and get urgent medical assessment.
  • Breathing trouble, throat swelling, collapse or severe chest symptoms after an injection: Call emergency services now.
  • Fever, shaking chills, rapidly spreading redness or feeling very ill after injection: Seek urgent care for possible infection or a contaminated injection.

Who should avoid it

  • pregnant: Avoid exposure. Pregnancy safety and fetal effects have not been established.
  • breastfeeding: Avoid exposure. Transfer into milk and infant safety are unknown.
  • tryingToConceive: Fertility effects and a safe interval before conception are unknown.
  • under18: No pediatric dosing or safety study was found.
  • kidneyDisease: Human clearance and dose adjustment are unknown; kidney-model benefits do not establish safety in kidney disease.
  • liverDisease: Human liver safety and dose adjustment are unknown. Improved mouse liver tests do not establish human safety.
  • diabetes: Mouse glucose effects raise a theoretical interaction concern with diabetes medicines; the human effect is unknown.
  • heartCondition: Stressed blood-vessel cells had lower viability with NNMT inhibition; clinical heart effects are unknown.
  • psychiatricCondition: Mood blunting is anecdotal. A lab MAO-A signal raises an untested medication-interaction concern.
  • activeCancer: Cancer experiments are not human cancer treatment evidence. Review use with the oncology team.
  • surgeryPlanned: Tell the surgical team about use; no evidence-based stop interval or anesthesia interaction study was found.
  • testedAthlete: S0 covers unapproved pharmacological drugs at all times. Applying that rule here is a class-rule interpretation.

Interactions

  • Insulin and sulfonylureas: Additive glucose lowering is theoretical from mouse findings. No human interaction study supports a medicine-dose change.
  • Serotonergic medicines: Lab MAO-A inhibition raises an untested interaction concern. Whether human exposure affects serotonin is unknown.
  • MAO inhibitors and stimulants: A lab MAO-A signal warrants medicine review. This is not proof that 5-amino-1MQ acts as a clinical MAOI.
  • GLP-1-based medicines: Users combine them, but added benefit, tolerability and effects on oral-drug absorption have not been tested in humans.
  • Anticoagulants and medicines needing close level control: No human interaction study was found. Effects on anticoagulation, drug levels or oral absorption are unknown.
  • Duplicate 5-amino-1MQ products: Capsules, blends and different salts may contain the same active molecule. Combining them can duplicate exposure.

Product quality risks

  • No independent peer-reviewed survey of marketed 5-amino-1MQ products was found. Its mislabeling and contamination rates are unknown.
  • FDA documented sterility failures at a facility making this compound. Its endotoxin-positive vial was NAD+, not 5-amino-1MQ.
  • A user suspected a wrong ingredient after marked urination; no lab result confirmed a diuretic or counterfeit product.
  • An HPLC purity percentage alone does not establish identity, milligrams per vial, sterility or freedom from bacterial toxins.
