AICAR vs SLU-PP-332
vs 5-Amino-1MQ
Three distinct paths to the same destination: mitochondrial biogenesis and fat oxidation without exercise training. This comparison covers AMPK activation, ERR nuclear receptor agonism, and NNMT inhibition — and which mechanism fits which research question.
AICAR
Directly activates AMPK, the master cellular energy sensor. Rodent models show a 44% increase in running endurance without training.
Shop AICAR →SLU-PP-332
Activates oestrogen-related receptors that govern mitochondrial gene expression, mimicking the transcriptional adaptations of endurance training.
Shop SLU-PP-332 →5-Amino-1MQ
Blocks NNMT, preserving intracellular NAD+ and activating SIRT1 — an indirect route to the same fat-oxidation and thermogenesis outcomes.

Mechanism Deep Dive
AICAR — Direct AMPK Activation
AICAR converts intracellularly to ZMP, an AMP mimetic that directly activates AMPK — flipping the cellular switch from anabolic to catabolic metabolism. This triggers fat oxidation, mitochondrial biogenesis, and glucose uptake, the same downstream effects triggered by prolonged exercise.
Shop AICAR →SLU-PP-332 — ERR Nuclear Receptor Agonism
SLU-PP-332 activates ERRα and ERRγ, transcription factors that sit downstream of exercise-induced signalling and control the gene networks for mitochondrial biogenesis, fatty acid oxidation, and slow-twitch fibre conversion — effectively mimicking the transcriptional endpoint of an endurance training adaptation.
Shop SLU-PP-332 →5-Amino-1MQ — NNMT Inhibition
5-Amino-1MQ blocks NNMT, the enzyme that consumes nicotinamide (an NAD+ precursor) and SAM. By preserving both, it may raise intracellular NAD+ and activate SIRT1 — an indirect route to enhanced fat oxidation and thermogenesis that converges with AMPK and ERR pathways downstream.
Shop 5-Amino-1MQ →Which Compound Wins For Each Goal?
Direct AMPK / energy-sensing research
AICAR
The most direct and well-characterised AMPK activator among exercise mimetics, with the largest rodent endurance dataset.
Muscle fibre-type conversion research
SLU-PP-332
ERRα/γ agonism specifically drives slow-twitch (Type I) fibre conversion, a distinct effect not shared by AICAR or 5-Amino-1MQ.
NAD+-linked metabolic research
5-Amino-1MQ
The only one of the three that works through NAD+ preservation, making it a natural pairing with NAD+ or sirtuin-focused protocols.
Comparative exercise-mimetic mechanism studies
All three together
Running parallel protocols isolates AMPK-driven, ERR-driven, and NAD+-driven contributions to the same downstream metabolic phenotype.
Frequently Asked Questions
What do AICAR, SLU-PP-332, and 5-Amino-1MQ have in common?
All three are studied as 'exercise mimetics' — compounds that reproduce some of the metabolic adaptations of aerobic exercise (fat oxidation, mitochondrial biogenesis, endurance capacity) without physical training. Each reaches that outcome through a different molecular pathway.
What is the mechanistic difference between the three?
AICAR directly activates AMPK, the master cellular energy sensor. SLU-PP-332 activates ERRα/ERRγ nuclear receptors that control mitochondrial gene expression. 5-Amino-1MQ inhibits NNMT, an enzyme that otherwise depletes intracellular NAD+ — indirectly supporting the same metabolic pathways from a different angle.
Can these three compounds be researched together?
Because they act on distinct nodes of the same broader metabolic network (AMPK, ERR nuclear receptors, and NAD+ availability via NNMT), they are of interest for comparative or combinatorial protocols studying convergent versus independent effects on mitochondrial biogenesis and fat oxidation.
