Let customers speak for us
from 17 reviewsSo my partner wanted to give these a trial! he is 55 and in his words it gave him more stamina, and increased his energy and focus levels, and did increase his libido as well as an enhanced performance so he tells me, he said they had no aftertaste and were easy to swallow, bearing in mind this is a supplement not a cure but i would suggest taking them for a while as like anything it takes time! i wasn't overall keen on the picture on the container.. but we ain't eating the container but surely theres a better image that could have been used? good amount of capsules and was pretty please with what i gainned from taking them!
Easy to use, effective supplement.
My husband, who wanted to explore options for enhancing his stamina and performance, even though I felt he didn’t need it, got this aptly named supplement. He was particularly interested in the idea of maintaining energy and endurance for longer, not just for the obvious use case but also during workouts instead of pre-workout drinks.
The supplement combines citrulline, known for its potential in boosting nitric oxide production, with resveratrol, which has various health benefits. My husband has found that it's easy to take and has helped him feel more energetic.
The capsules are easy to swallow thanks to their pretty standard small size, thus no taste can be noticed when taking them. There seems to be nothing wrong in terms of quality and there were no adverse reactions or side effects.
The value for money appears to be reasonable at 33p per capsule (66p per two-capsule serving).
As a guy in his late 40s, I haven't had any trouble with the physical side of my love life which would need little blue pills, but inevitably things decline a little as you get a little older, and things aren't always quite as intense or firm as they used to be - everything still works as before and it's still good, just dialled down a little bit in intensity and hardness, so I try supplements like this more out of curiosity to see if they can help without any real expectation that they will.,
I also take fenugreek - if you see my other reviews you can see I've had some success, but I was interested to see if these would add anything, as I was intrigued to see they are based on an actual clinical study.
It's early days, I'm less than halfway through the bottle, but I think I can see a subtle effect - just that extra little bit of intensity and firmness, reminding me of when I was younger. It's subtle, but I think it's genuinely there.
The ingredients are good for you anyway, and they're made in the UK so I trust that they will be safe to use, so they're worth a try.
The brand name made me smile a little ruefully, but you'd probably want to keep these hidden - they're certainly not discreetly packaged!
I'd finish them off and update the review if I notice any further improvement. I don't think you should expect miracles, but they're reasonably priced enough to be decent value and are worth a try to see if they give you that extra edge.
ultimately I was really looking for a new source of Citrulline for both athletics and sexual health and these appears to be of good quality, made in UK and the pill size is significantly smaller than many other suppliers.
I am a huge advocate for Citrulline - I know it works, and so finding an easy reliable source is very important.
The portion size here is in line with my beliefs and experiences, and the additional ingredients intrigue me, especially after further research, 150mg Resveratrol, and 5mg Black Pepper Extract.
This doesn't taste of anything at all and I know to be effective already and in line with my other supplies.
Good value for money at the current price.
Funny name mind.
I do not use prescription medication, but I was looking for something to enhance performance and add a bit more confidence. This really delivered. Within a few days, I noticed quicker response and a level of firmness I had not experienced in a long time. I take two capsules in the morning and that is it—no need to plan around it, just steady readiness when the moment calls for it. The effect feels natural rather than forced, and I have not experienced any unwanted side effects. If you are looking for something to help sharpen things without going down the prescription route, this is a solid and straightforward option.
It works! Harder, stiffer, and I think bigger erections achieved within days of taking the daily dosage. Need I say more.
I was going to attach a before and after picture with the review, but I think it would get removed 😂
I have documented the difference though, wanting to check my own anecdotal experience against the results of the studies.
I'm 100% getting harder (and bigger) erections since taking King Dong - I even took fully-erect measurements before and after. I'll be coy and only mention the actual difference (not the full measurement - it's not that impressive), and circumference is 0.3cm longer than before taking King Dong along with a lengthening from base-to-tip of just under 1cm - which is substantial! It's visibly bigger.
I know this isn't what the product is marketed-for, but it's clear that it is causing greater bloodflow and 'filling out' my penis more during an erection. It's also far easier for me to become aroused - I'm having to be careful what I'm thinking about whilst in public places or it could lead to a very embarrassing scene.
Please please please, launch a subscription option on your site. I do not want to be without this product. Ever.
Wasn't going to reorder because the price seems to have gone up since I last ordered on promotion.
However . . .
I went through my whole first pot consistently over 30 days, and thought that I didn't really feel much different - though, to be fair, I've never had a problem in that department, I just ordered this after seeing it on TikTok and wanted to see if it gave me a boost.
I ran out because I saw the price increase and wasn't bothered about re-ordering, but since coming off the first batch I have realised that frequency of sex with my partner has reduced. It could just be coincidence of course, but I have realised that it takes a bit more to get me aroused when I'm not taking King Dong. During the last batch we were having sex around 4-6 times per week and since I came off it, this has fallen to 2-3.
Like I say, I'm not sure if this is just coincidence or whether it was placebo effect whilst taking it, but something has definitely changed for the worse since coming off King Dong.
I've just placed another order now, and will report back on how it impacts bedroom activity! Seems to certainly help with arousal/ease of gaining an erection, which ultimately leads to more sexual activity.
I know the studies on which this is based were really small, so I was skeptical about the 'clinically-proven' claims but I have to say - this is the real deal. Noticeably harder, longer-lasting erections from day one. I do take Sildenafil too, with limited success - but since I've combined with King Dong I've had 100% success rate (touch wood). Excuse the pun!
The difference is definitely noticeable.
I'm fairly sexually active anyway with my long-term partner of over 27 years - we have sex at least 4 times a week (I know, I'm lucky!). I also masturbate a couple of times a week on-top of this.
Maybe 1/3-1/4 of the time, I notice during sex that I'm not 100% hard (maybe around 70-80%) - and strangely not always closer to one of the times that I've masturbated, it depends more on my mood/relaxation etc. Not enough to stop the show, but noticeable - not the maximum pump feeling I get on better days.
I've now been taking King Dong for over 3 weeks, daily, and I've not had anything less than maximum hardness during every sex session since I started. In fact, the pump sometimes starts to throb it's that intense - something I've not felt since my late teens/early twenties!
I've never needed V***ra or anything pharmaceutical to get going, but I ordered King Dong to just see if it could bring me back to full performance every time, and I am NOT disappointed. You've got yourself a customer for life.
Can't recommend this enough. I bought on the pre-order sale - a little dubious having tried these sorts of things before and having no joy, and also taking 5-6g of citrulline anyway daily.
Since the first dose, I definitely felt more 'activated' and ready to go much quicker than before.
The other evening, I was massaging my Wife's hair, she leaned her head back into my groin as I was massaging her head, and I started to get erect just from the pressure from the back of her head pressing on me. Needless to say we cut the massage short and took advantage of the situation 😉
I can't think of a better way to describe it than just feeling more 'activated' and ready to go! It's not like I'm walking around hard, but it seems like I need MUCH LESS stimulation than I did before to get going - and it's reaching peak hardness much more frequently, I can feel a throbbing almost immediately on getting hard, and my Wife has commented on me feeling much firmer/bigger during intercourse.
Top marks - awesome product.
I’m 72 and have been married for over fifty years. In recent times, I noticed my erections were weaker and harder to maintain, which left me feeling discouraged. My doctor recommended continuing my low-dose PDE5 inhibitor, but I still felt something was missing. Six weeks ago, I added King Dong to my nightly routine.
Prior to King Dong, I often struggled to achieve a fully rigid erection, even with medication. With King Dong, I now reach a strong 4/5 hardness on a consistent basis, and it lasts long enough for both my wife and me to fully enjoy the experience without interruptions.
My wife and I had grown accustomed to shorter, more tentative encounters. Since starting King Dong, our intimacy feels closer to how it was decades ago—longer, more satisfying, and decidedly more passionate. She remarked that I seem “younger” down there, and I feel that difference every time we’re together.
Beyond the physical aspect, King Dong has lent me a boost in confidence. I no longer approach our intimate moments with apprehension. Instead, I feel eager and prepared, which has positively influenced our relationship and overall sense of closeness.
Gentle Side Effects: At my age, I worry about adding supplements. King Dong’s ingredients have actually led to reduced blood pressure readings at the doctors too, from 146/87 down to 132/85! I don't know if this is from the more frequent sex I'm now having and the stress relief this brings, or if it's from the supplement itself. I did some reading on citrulline/resveratrol and blood pressure and it does seem it could be the supplement. So an added benefit!
King Dong is not a magic cure—my age still dictates a slower response—but it has restored a level of performance and enjoyment I feared was gone forever.
Feel like I'm spending my life with a constant boner. No idea if it's the placebo effect or if it's the actual supplement working, but things just feel different - almost constantly pulsating, like I'm constantly aware of what's in my pants. Not necessarily just when erect, it just feels ALIVE. Can't recommend enough.
If you’re a thirty-something or forty-something dude who’s been sidelined by ED—especially one that’s post-injury or post-stress—King Dong is like the wingman you didn’t know you needed. It’s not a miracle overnight fix, but by Week 3, you’ll be reclaiming your bedroom kingdom faster than you can say “testicular fortitude.” As for my marriage: my wife remarked, “I forgot how fun you could be.” I’m pretty sure her grin could be seen from space. King Dong didn’t just get my flair back; it gave us a brand-new lease on our sex life. Recommended for anyone ready to trade in the floppy shrimp for a full-fledged lobster.
