A research compound known as a synthetic ERR (Estrogen-Related Receptor) agonist that significantly increases metabolic rate and energy expenditure. SLU-PP-332 essentially amplifies the body’s exercise response pathways, leading to a short-term spike in calorie burn and endurance. In simple terms, it’s like a non-stimulant cardio enhancer – causing the body to burn more calories and use more fat for about 1.5 hours, making workouts more effective.

Boosts metabolic rate dramatically for a short period (~90 minutes), meaning more calories burned and more fat metabolized during that time
Improves insulin sensitivity, helping muscles uptake glucose more efficiently and lowering blood sugar levels
Enhances cellular respiration in muscle cells – essentially makes mitochondria burn fuel more efficiently and at a higher rate
Provides an acute surge in energy and endurance (users feel an increase in stamina and less fatigue during cardio)
Increases cardiovascular endurance and performance (heart and muscles work more effectively under strain)
Potential ancillary health benefits: good for heart health and kidney health (as per research on ERR agonists, which often show protective effects in these organs)
Shows experimental anti-cancer activity, particularly in prostate cancer models, by catabolizing (breaking down) cancer cell energy pathways – though this is a very specific and ongoing area of research
Take 1 mL (20 mg) sublingually once per day. For best results, use it 30–60 minutes before exercise, especially before cardio or high-intensity interval training. Administer sublingually (under the tongue) and hold for around 60 seconds, then swallow – this ensures faster absorption. If not exercising, it can be taken in the morning to boost resting metabolism, but the effects are most beneficial when paired with physical activity. Do not exceed 1 dose per day. Because the compound is quite potent in raising metabolism, starting at a lower dose (0.5 mL = 10 mg) for the first few days to assess tolerance is prudent. Important: Stay hydrated and monitor how you feel – if you experience excessive sweating, rapid heart rate, or dizziness, reduce dose or discontinue. Store the liquid at room temp away from sunlight.
SLU-PP-332 is an Estrogen-Related Receptor (ERR) agonist. ERRs (such as ERRα, ERRβ, ERRγ) are orphan nuclear receptors that regulate genes involved in energy expenditure and mitochondrial function. Unlike the name might imply, they don’t bind estrogen – instead, they control metabolic genes. When SLU-PP-332 activates ERR pathways, several things happen:
Increased expression of metabolic genes: It upregulates genes like Pdk4 (pyruvate dehydrogenase kinase 4) in muscle cells. PDK4 shifts the cell’s fuel usage from glucose towards fatty acids. This mimics a fasting or exercise state where the body burns more fat. That’s why SLU-PP-332 encourages the body to utilize fat for energy.
Enhanced mitochondrial respiration: Studies in cell lines (e.g., C2C12 muscle cells) have shown that activating ERR with compounds like this enhances the oxygen consumption rate of mitochondria. Essentially, cells burn nutrients faster and produce more ATP and heat – the basis of increased metabolic rate.
Increased oxidative muscle fibers: Long-term activation of ERR pathways tends to promote the formation of more oxidative (type I) muscle fibers, which are endurance fibers. This was seen as an increase in markers of oxidative metabolism in skeletal muscle tissue upon ERR agonism.
Acute effects on calorie burning: Immediately after dosing, SLU-PP-332 triggers a cascade that leads to ~90 minutes of heightened caloric expenditure and thermogenesis (heat production). Users literally run “hotter,” similar to how one feels during intense exercise or after taking a thermogenic compound, but notably without the use of a stimulant. It works at the muscle cellular level rather than through the nervous system.
Insulin sensitization: By improving muscle fuel uptake and usage, insulin works more effectively. ERR activation has been linked to improved glucose handling by muscles. The end result is like flipping a metabolic “turbo switch.” For about an hour and a half, the body is expending energy at an elevated rate (could be 5–10% above baseline metabolic rate, for example). In practical terms, if you normally burn 500 kcal during a certain workout, on SLU-PP-332 you might burn significantly more, and utilize more fat in the fuel mix. It’s akin to some effects of Rev-Erb agonists or AMPK activators, but through a distinct pathway (ERR). Interestingly, research noted improved aerobic performance in models treated with ERR agonists – likely due to more efficient energy production and reduced lactic acid buildup. The mention of being “good for heart and kidney health” and “catabolising prostate cancer cells” refers to experimental findings: ERRγ agonists have cardioprotective effects (by improving heart muscle metabolism) and in some lab studies, forcing cancer cells to over-metabolize can slow their growth. However, these are peripheral possible benefits under investigation and not primary reasons for fitness use.
This is a cutting-edge research compound; human use data is limited. Some users liken its effect to a non-jittery pre-workout that notably increases sweat and endurance. Always listen to your body – if you feel overly warm or uncomfortable, ensure you’re not in a hot environment and stay hydrated. There is no significant stimulant effect (it won’t give you a rush of adrenaline), so don’t expect a dramatic immediate “feel” beyond maybe some warmth. But the metabolic boost is real on a cellular level. It’s wise to avoid taking it late in the evening as an elevated metabolism could interfere with sleep onset for some (though it’s not a CNS stimulant). Also, given it works on nuclear receptors, consistency might yield better results (taking it daily around the same time). This compound amplifies an exercise response, so pairing it with actual exercise will maximize benefits – think of it as an exercise potentiator. Finally, keep it in a cool, dry place; being a research chemical, handle it with care and make sure to use accurate measuring tools (the dropper provided or an oral syringe) for dosing.
