Enhanced Labs Maximus Pump: Stim-Free Pre-Workout
Maximus Pump is a fully caffeine-free pre-workout designed around four performance pillars—pumps, strength, endurance, and focus—using 17+ synergistic ingredients and 8 patented compounds to deliver a comprehensive training experience without stimulants.
No caffeine means no jitters, no crash, and no sleep disruption—making it equally effective for early morning sessions, late-night training, or stacking with a separate stimulant pre-workout on heavy days.
Quick Specs
- Serving size: 1 scoop (20.53g) | 20 servings per container
- Stimulant status: 100% caffeine-free
- Key doses: 8g L-Citrulline, 3.2g Beta Alanine, 3g HydroPrime™, 3g Betaine Anhydrous, 1.5g Nitrosigine®
- Patented compounds: 8 (Nitrosigine®, HydroPrime™, PeakO2®, ElevATP®, EndoFlo™, GeniusPure™, NeuroRush™, S7®)
- Made in an FDA-inspected facility
Four Performance Pathways Explained
Rather than relying on caffeine to drive every aspect of performance, Maximus Pump addresses pumps, strength output, endurance, and cognitive focus through dedicated ingredient groups that work simultaneously across each training session.
Pump & Vascularity
L-Citrulline (8g), Nitrosigine® (1.5g), HydroPrime™ Glycerol (3g), Beet Root Powder (500mg), and L-Norvaline (100mg) work together to support nitric oxide production and promote enhanced blood flow and muscle fullness during training.
Strength & Metabolic Support
Vitamins B3 and B12 alongside ElevATP® (150mg) and Himalayan Pink Salt (100mg sodium) help support cellular energy production and electrolyte balance to promote sustained power output throughout the session.
Endurance & Fatigue Resistance
Beta Alanine (3.2g) and Betaine Anhydrous (3g) help buffer lactic acid accumulation, while PeakO2® (1g) and EndoFlo™ (200mg) work to support oxygen utilization and help maintain training capacity over time.
Focus & Mind-Muscle Connection
GeniusPure™ Alpha GPC 90% (150mg), NeuroRush™ (100mg), and Huperzine Extract (10mg) promote cognitive sharpness and help maintain concentration throughout training without stimulant-driven anxiety.
Full Ingredient Profile
Pump & Blood Flow Compounds
- L-Citrulline 8g: Full clinical dose to support nitric oxide synthesis and promote muscular blood flow and endurance.
- HydroPrime™ Glycerol 65% — 3g: Patented high-purity glycerol that promotes hyperhydration in muscle tissue for increased fullness and pump.
- Nitrosigine® 1.5g: Patented inositol-stabilized arginine silicate shown to support arginine levels and help maintain nitric oxide production before and during exercise.
- Beet Root Powder 500mg: Natural source of dietary nitrates to further support blood flow pathways.
- L-Norvaline 100mg: Arginase inhibitor that helps extend nitric oxide activity by reducing arginase breakdown.
Strength & Energy Support
- Betaine Anhydrous 3g: Promotes cellular hydration and supports strength and power output at clinical dosing.
- ElevATP® 150mg: Patented ancient peat and apple extract blend studied for its role in supporting intracellular ATP production.
- Vitamin B3 (Niacin) 20mg NE (125% DV): Supports energy metabolism and promotes healthy blood flow through vasodilatory mechanisms.
- Vitamin B12 (Methylcobalamin) 250mcg (10,417% DV): Active form of B12 to support energy production and red blood cell formation.
- Sodium (Himalayan Pink Salt) 100mg: Electrolyte support for hydration balance and sustained energy during extended sessions.
Endurance & Resilience
- Beta Alanine 3.2g: Full clinical dose to help buffer muscle acidity and support muscular endurance during high-intensity efforts.
- PeakO2® 1g: Patented adaptogenic mushroom blend (Cordyceps, Reishi, King Trumpet, Shiitake, Lion's Mane, Turkey Tail) to help support oxygen utilization, VO2 max, and training capacity.
- EndoFlo™ 200mg: Patented blend of Mangifera indica, Kaempferia parvifloria, Ginkgo biloba, and Pinus massoniana to promote endothelial function and blood flow efficiency.
- S7® 50mg: Patented plant-based antioxidant complex (Green Coffee, Green Tea, Turmeric, Tart Cherry, Blueberry, Broccoli, Kale) to help reduce oxidative stress during training.
Focus & Cognitive Support
- GeniusPure™ Alpha GPC 90% — 150mg: Premium high-bioavailability choline source that promotes acetylcholine production to support focus and mind-muscle connection.
- NeuroRush™ 100mg: Patented Coffee arabica fruit extract studied for its role in supporting cognitive performance and mental clarity.
- Huperzine A Extract 10mg (std. 1%): Acetylcholinesterase inhibitor that helps sustain acetylcholine levels to support prolonged mental sharpness during training.
Synergistic Formula Design
Maximus Pump is structured so each performance layer reinforces the others: the pump complex drives blood delivery, the endurance stack keeps muscles working efficiently, the strength support feeds cellular energy, and the nootropic layer maintains the cognitive output needed to capitalize on the physical effect.
Pump Synergy Deep Dive
L-Citrulline raises plasma arginine; Nitrosigine® extends and stabilizes that arginine pool; HydroPrime™ promotes intracellular water retention; Beet Root adds dietary nitrate substrate; and L-Norvaline blocks the enzyme that would otherwise break down arginine—creating a full-circle pump system at every step of the nitric oxide pathway.
Stim-Free Versatility
Because Maximus Pump contains zero caffeine, it can be used at any time of day. On heavy training days, Enhanced Labs recommends stacking it with Maximus Stim to layer stimulant-driven energy on top of the pump and endurance foundation already in place.

I love indie authors
Format: Kindle
Let me preface this by saying—writing a book is HARD! Coming up with characters so real that they take on a life of their own, building an entire world, the political/magic system. Designing all of this is no easy feat.
That being said.
This book had so. Much. Potential. I was so excited to read this book, and I plan to finish it for the sake of finishing it. But. At this point, I would have set I’d aside as a DNF. The book could have benefited from some form of a developmental editor, or an in depth beta reader. I will say this. Within 5 chapters, there are so many… phrases that I’ve highlight that I’ve latched onto. Phrases about books and storms that were written BEAUTIFULLY! So, bravo Linton for hitting the nail on the head as to why readers disappear like they do!
However, 5 chapters in and I can already guess where a majority of the story is going. But that’s also because I read like a mad-woman and have read this particular type of story, many different ways. Enemies to lovers where the FMC isn’t who she thinks she is. I am all about supporting indie authors. BUT. I also feel like criticism should be constructive, and not degrading. So if I could give this book a 4 1/2, strictly because I know the work the author put into this, I would. So if you’re looking for an easy read with characters that aren’t hard to follow, look no further! They are easy to love and easy to care for. One of the biggest issues they lacked, to me, was depth and plausible reactions to their situations. JD, you have done BEAUTIFULLY writing this book. I applaud and will continue to buy your books in the future. My BIGGEST recommendation is to definitely hire some form of an editor for any upcoming books. Or in turn, I will be happy to beta read for you. Should my opinion change of the book by the time I finish, I will happily get on here and say I was wrong, delete this review and post a different one. Until then…

this book set my soul ablaze! <3
Format: Paperback, Format: Paperback
"i had never really cared about the weather before, but now, clear skies meant everything to me, and i was grateful to see another calm morning."
this book. this book!
i loved the last storm so much. the writing style. the descriptions. the world-building. the characters. the plot twists. the tropes. the sexual tension. the—everything. everything was magic.
the last storm follows our two main characters, ara and rogue, giving us dual POV from both characters (which i loved, btw). ara, a human girl who has been locked away in her father’s estate most of her life, just wants to see the world. all she dreams of is seeing what else is out there. but when her father announces her engagement, she knows that dream will become nothing more than just that—a dream.
rogue, the fae king, is tired of the attacks being rained down on his people. in hopes of finding out the human king adon’s secrets, rogue infiltrates auryna’s borders. in his last resort to gain information, he visits the local pub. to his surprise, the general’s precious only child is sitting at the bar, drink round after round of mead. now he just needs to figure out how to take her without anyone noticing.
first and foremost, let’s talk about the endless list of my favorite tropes and aspects that this book had.
›› enemies to lovers
›› fated mates
›› one bed
›› the chosen one
›› elemental magic
›› actually good and shocking plot twists!!!
›› badass female lead
›› morally-grey love interest
›› fae/human war
›› force proximity
›› touch her and die
›› who did this to you?
›› captor/captive
›› praise k!nk (panting profusely)
“you are entirely the opposite of everything that i am, and i would gladly wear your shackles if it meant i could have you.”
it’s been a long while since i read a book i liked this much. but i just loved this book. it set my soul ablaze. thank you to the author for writing this beautiful story and for blessing me with an eARC! i loved it so much that i immediately bought the paperback upon release!
every aspect of this book was just beautiful. i was blown away by the way the world was described, the way feelings were portrayed, the way the elements were used in the fae’s magic. it just—AHHH! i just absolutely adored it all. i cannot wait for the second book to release next year!
also the way he calls her “little storm” sets my heart on fire.
this was a fast-paced read and if you are a lover of acotar, fbaa, deal with the elf king, or any other similar books, then please stop everything you’re doing and read this book right now. you won’t regret it.
thank you again, jd linton, for giving me the privilege of reading your arc and for blessing this world with the world you created. <3
"something about him pulled me in, like a moth to a flame, and it felt as if i was just waiting for the inevitable burn that came with flying too close to the fire."

Fun, both heartwarming and heartbreaking
Format: Kindle
Only my second first person written selection, I am still getting used to that aspect, but unlike my first, I enjoyed that the story was told through both MCs. A great enemies to lovers, forced proximity, fated love etc, that resonated to me. There were some small twists that I could see coming, but also a few that I didn’t quite see until the characters were also seeing. Personally, I am more interested in the story than the spice, but with that said, it was well seasoned! I am kind of new to the spice world so I can’t say for sure how this would rate, but it definitely had some heat. I am very glad I happened across this author, and I do plan on also reading the next book….if nothing else, just to see for myself the “transformation” of the characters I’ve grown to love!

😍😍 BEST DEBUT NOVEL EVER
Format: Paperback
I’m having trouble finding accurate words to describe the way this book made me feel, but I am going to do my best.
To start off with basic elements, the character and world building are phenomenal. I feel a strong bond to not only the two main characters, Ara and Rogue, but to each and every character introduced throughout the book. The author did a stellar job of giving each of them unique personhood. All of the scenes are beautifully described. So much so that throughout the entirety of the book, I could see every scene: the towns, the castles, the meadows, the landscape. I have had difficulty with this and with distinguishing between outlying characters while reading in the past, but I did not have to think to remember details of world or character building because they flowed naturally within the story and were described well. I have read book series before that made me want to be a part of that world, but I actually felt like I got to step into Auryna and Ravaryn!
The plot twists!! Although this is not a suspense novel, it still had me on a rollercoaster of emotions and on the edge of my seat from beginning to end. I haven’t cried actual tears over a book since I was in high school (and I’ve read a LOT). This book finally broke the floodgates in the final few chapters. Multiple times. And we love a good cliffhanger. It truly made me FEEL.
THE SPICE is a solid 3.5/5. Some of the scenes had me flushed, some had me taking notes, some just had my jaw slack and my mouth hanging open. Bravo, JD Linton, bravo.
The relationships: friendships, family, romantic, ALL of the relationships in this book have so much meaning. The author does a great job at making you feel the love, the anger, the peace, the frustrations, the safety, the familiarity, etc. between the characters.
Ara and Rogue. I can not say enough and I also do not want to say too much. Just know that I feel like I know them both, to their core. I know what their childhood looks likes, their darkest moments, their biggest fears, their dreams and passions, what they want in life… The POV switches were seamless. I am so happy this author decided to let us see from both sets of eyes.
I can not wait for book two after that cliffhanger. And there is SO much potential for at least one prequel, I can’t wait to see where this author goes! I hope this series continues and flourishes. Fingers crossed!

Amazing!
Format: Kindle, Format: Kindle
This book was phenomenal, I devoured it within a few days! For this being a debut novel, it is fantastic and I would’ve thought the author was a seasoned author. I have zero complaints about this book.
Let me start by saying that the world building was phenomenal. I could picture everything in my head because of how detailed it was — that’s how good it was written. And I absolutely love the “captive/captor” trope so much, it’s become one of my favorite tropes, so I was pleasantly surprised to see that this book had that.
I loved the banter between Rogue and Ara — they’re both snarky and witty, plus with the romantic tension, it made the dialogue that much better. Speaking of romantic tension, yes there is spice but not so much of it that it overrides the plot, which I loved. For me, this would probably be on the 3/5 level of spice.
This book had a ton of plot twists and I thoroughly enjoyed it.
