Glycerol pulls water into muscle cells for deep cellular hydration, translating to harder, fuller contractions every rep.
🔄 Full-Cycle NO Delivery:
Citrulline → Arginine → Agmatine—our layered NO-precursor stack drives blood flow from multiple angles for peak vascularity.
⏳ Extended Pump Duration:
Agmatine blocks NO-breakdown enzymes, locking in your pumps set after set and keeping that “just-popped” feeling longer.
🏃 Improved Muscular Endurance:
Sustained vasodilation means better nutrient and oxygen delivery—push deeper into your workouts with less fatigue.
🌬️ Lower Perceived Effort:
By enhancing blood flow and hydration, Psycho Syrup makes each set feel smoother and less taxing on your CNS.
💪 Reduced Post-Workout Soreness:
Optimized circulation and cellular hydration help clear metabolites faster, so you bounce back quicker.
😊 Euphoric Pump Buzz:
Agmatine’s dopamine-supporting action adds a subtle mood boost—enjoy that feel-good side of the pump with zero stimulants.
Ingredients
Glycerol: 10g / 20g
Glycerol is an osmolyte — meaning it pulls water into muscle cells, leading to deep cellular hydration and skin-splitting pumps.
It’s one of the few ingredients clinically shown to induce true hyperhydration, which translates to more volume, more endurance, and harder contractions.
Benefits:
Increased power output
Improved muscular endurance
Fuller, longer-lasting pumps
L-Citrulline: 1.5g / 3g
L-Citrulline kickstarts the nitric oxide pathway by converting to L-Arginine, elevating NO levels more effectively than Arginine itself.
This makes Citrulline the front end of the pump cycle — driving blood flow, boosting performance, and reducing fatigue.
Benefits:
Increased nitric oxide production → bigger pumps
Improved power output
Reduced muscle soreness
Enhanced endurance
Lower perceived effort during training
L-Arginine: 500mg / 1000mg
L-Arginine continues the nitric oxide cycle, acting as a direct NO precursor.In combination with Citrulline, it helps flood the bloodstream with nitric oxide, increasing vasodilation and endurance.
Benefits:
Increased nitric oxide production → more vascularity
Lower blood pressure
Lower triglycerides
Improved VO2 max
Enhanced endurance
Arginine also metabolizes into Agmatine, continuing the cycle.
Agmatine Sulfate: 750mg / 1500mg
Agmatine is the final stage of the nitric oxide pump stack.It not only promotes vasodilation but also inhibits the enzymes that break down nitric oxide — keeping pumps locked in longer.Plus, it boosts dopamine for mood and motivation.
Benefits:
Strong vasodilation → extreme pumps
Dopamine support → enhanced mood and motivation
Protection against oxidative stress and cellular damage
Inhibition of nitric oxide breakdown → longer pump duration
Neuroprotection
PUMPS ON DEMON TIME

Its new to me but its an effective preworkout no doubt, id buy it again 💯.
The Diffrence in the pump is ridiculous. Last chest day i had a fullscoop of Edge of insanity with a cap of Psycho Syrup. By the end of the session my triceps and chest had practically exploded. I could not get over the leve of pump I had engorged myself with. Had me feeling myself forsure. love the stuff for sure
Stuffs great and kicks in quick I get more pumps in the gym and I can go heavy I like to stack it with edge of insanity preworkout and the psycho pharma creatine thunderstruck works well also! Just absolutely great and glad I found a brand that works for me! Preworkout tastes great! Just A+ product and I've gotten great results with psycho pharma and their products!
I've tried a few other glycerol based pre workouts and this one is the smoothest and tastiest one by far with the same effects. Im very impressed by it.
Definitely a great mix of Glycerol and L Citrulline!!!
I mostly use half scoops from all the strong brands like Gorilla Mind, Bucked Up and Psycho Pharma. Definitely hydrated throughout the day of workout 💪 I can easily stay in the gym for at least 2 hours jumping around between machines while most guys already leaving by 45 minutes 😆🔥
This is a lot like a vitamin. You take it and assume it's working. I can't say if my pumps or better or whatnot with it, but I do like to add it to my preworkout. I can't consume yohimbine, otherwise I'd take Edge, but instead I take a different product, one that contains 350mg of caffeine, plus Psycho Syrup, 30mg of maltodextrin, one tablespoon of MCT oil, and a pinch of sea salt.
I like adding this to my preworkout stack because I feel it does help in concert with these other items.
What throws me off and might throw you off is that it's called "Psycho," and I guess one just expects to "feel" a product that called "psycho." I guess that's on me.
But I'll tell you this: when I read Eric's email and saw this was on sale, I restocked. So I like it enough to buy it again.
This is a product I've recently purchased and I haven't used it long enough to give an opinion. If it's like the other products from this company I'm sure it will be great!
I have both the unflavored and flavored. the pump from these are insane. I will always restock these when I run low. highly recommended for those who want no caffeine but an insane pump!
I absolutely love this stuff. Ive mix it with multiple flavors and they all tasted great. When it first came out the lid design wasnt good and leaked like crazy in a gym bag. Im glad to see they fixed it.
Juicy pumps that’s not for chumps!
Taste of the unflavored is alright if not a little bitter by itself but when mixed in with edge of insanity it hits hard
Holy pump! Best pre-workout I have ever taken. Fast into the system, great pump, more endurance, fast recovery. Oh, and it tastes f'n great. Do yourself a favor and order purple drank today.
