Following a comprehensive, millennial-focused rebrand, Olympus Labs has reformulated some of their most effective products. One of the brand’s most popular supplements, K1ngs Blood, which was already one of our favorite testosterone boosters, has now gotten even better! In fact, it acts more like a hormone optimizer – it regulates healthy testosterone levels in men, as well as balances estrogen levels in women.
Hormonal Help for Everyone
This supplement has some incredible stuff to offer, and it’s ridiculously versatile, so there are a number of reasons to use it. After our analysis below, we realize that unlike other “testosterone boosters”, this one likely has enough clinically-backed ingredients to provide benefits even to healthy young males!
Read on for our in-depth breakdown of K1ngs Blood, where we’ll give you an ingredient-by-ingredient analysis, as well as potential uses and benefits! But first, make sure you check out PricePlow for price comparisons and sign up for Olympus Labs news and price alerts!

K1ngs Blood Ingredients
The following comes in a full day’s supply of eight capsules. We cover dosing below.
Mucuna Pruriens P.E. [(seed) std min. 20% L-Dopa] – 1.2g
K1ngs Blood comes out of the gate quick, hitting us with some well-dosed Mucuna pruriens. In fact, it’s a dose that practically nobody is using!
Also known as “velvet bean”, Mucuna pruriens is used for its high concentration of Levodopa (L-dopa). L-dopa is capable of boosting levels of the hormone dopamine within the body, and science has found many different potential uses for L-dopa that warrants its high placement on this label! But what about our hormones?
L-dopa and your hormones
Much of the focus with L-dopa revolves around its interactions with the pituitary gland, which is responsible for hormone secretion. Daily life can lead to large fluctuations in our hormonal levels, thanks to things like cortisol (from stress!) disrupting things. Thankfully, there are potential solutions for distorted hormones, and L-dopa is certainly one of them!
Researchers going as far back as 1972 knew that there was sufficient evidence of L-dopa acting as a hormonal balancer. After receiving 500mg of L-dopa, 7 of 9 male test subjects had decreased levels of luteinizing hormone, while simultaneously showing no difference in individual growth hormone levels. This is important, as high luteinizing hormone levels can yield infertility in both men and women, while high levels of growth hormone also bring their own set of issues. This suggests L-dopa is beneficial for regulating luteinizing hormone levels in both men and women, which is why it’s a worthy ingredient in a versatile product such as K1ngs Blood.
Another study, albeit conducted on individuals with a neurodegenerative disease, showed that L-dopa reduced cortisol levels. The researchers conducting this experiment then suggested similar results would occur in all subjects, which is encouraging. Lower levels of cortisol will help your body function as it should, which is crucial in keeping your hormones in sync. If you have too much cortisol, you can say goodbye to burning an appreciable amount of fat, so it’s great to see anything bring it down.
L-dopa and testosterone
In men specifically, L-dopa has been shown to decrease prolactin levels. Prolactin is responsible for stimulating milk production, especially after childbirth, and suppresses testosterone levels.
In one study, men consuming 5g of mucuna pruriens daily for three months were shown to have higher levels of fertility. In addition, these subjects had increased levels of testosterone, dopamine and adrenaline. Although this dose of mucuna pruriens (and in turn L-dopa) was extremely high, this bodes well for its ability to keep testosterone levels higher in men. However, it’s important to note that this study was conducted on infertile men, and similar research has not been conducted on fertile men.
Yielding around 250mg of actual L-dopa (from 1.2g at 20% standardization), we are getting more than most companies use in total mucuna, but there’s still room for even more from partnering supplements like Olympus Labs Superior Protein Muscle Building Edition. Also, most studies do suggest that benefits can be had at lower doses, and although the effects may not be as prominent, we’ll still take it!
Ginger Rhizomes (10:1) Extract – 1g
Don’t let the word “rhizomes” confuse you – ginger rhizomes is a fancy term for ginger stem extract! Essentially, the rhizome is the underground stem of the ginger plant, which is commonly extracted for its medicinal properties. We are all very familiar with ginger and its anti-inflammatory properties (which stem from a high concentration of gingerol),[5,6] but we must ask, what else is it contributing to this label?
The key is in the extract strength — a 10:1 extract is effectively like getting 10g of ginger powder, assuming we’re going after the constituents that possess the qualities we’re after.
The ginger-testosterone study in men
The main reason for Olympus Labs to include ginger is because of a study published in 2012 where 75 infertile men had an increase in testosterone of 17.7%! This came alongside the other benefits they were looking for, such as an increase in sperm count and viability. FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone) were also significantly increased.
The study was three months long, which is a good thing because we’ve seen other testosterone-boosting ingredients perk test up, only to have things return to baseline by the end of the month. These gains endured!
Rat studies confirm, but the dose matters
Several rat studies also demonstrate dose-dependent responses, with testosterone increases that were not statistically significant at 50mg/kg/day, while they were significant at 100mg/kg/day, 500mg/kg/day, 600mg/kg/day, and 1g/kg/day. Remember, rat doses do not convert directly to human doses, but if you consider K1ngs Blood to provide 10g ginger, we are right in line for gains given the data above.
This is why we’re excited to see a monster 1g 10:1 dose here – and we’re not even done with the benefits of ginger:
Ginger helps relieve muscle soreness
Olympus Labs wants to make sure you’re feeling good each and every day, and giving you a healthy dose of ginger in K1ngs Blood is perfect for that. Specifically, ginger has been shown to reduce muscle soreness. Research has shown that at a daily dose of 2g raw extract, ginger tends to help alleviate day-to-day muscle pain, an effect likely stemming from the root’s anti-inflammatory properties. That’s important, as it means you’ll be better equipped to hit the gym hard each and every training day! Assuming Olympus Labs has extracted the parts that make this anti-soreness effect work, our 10g equivalent is more than enough here.
It helps keep your heart healthy
Cardiovascular health cannot be overstated, and, it’s no surprise that Olympus Labs wants to enhance it to some degree here. In a study published in 2015, ginger extract was shown to lower blood sugar in fasted diabetics. It also improved haemoglobin A1c (HbA1c) levels, which is a strong sign of potential long-term blood sugar level stabilization. This same study also found ginger had lowered lipid peroxidation. These are all precursors of heart disease, which means that ginger can help reduce the risk of heart disease. The above benefits are why we also see ginger in the revamped Olympus Labs Ignit3 fat burner.
Ginger and the menstrual cycle
Playing more into the “hormonal balancer” for females that K1ngs Blood claims to be, it turns out that ginger may help reduce menstrual pain. One study from 2009 cited that women who ingested 1g of ginger for the first 3 days of their menstrual cycle reported significant pain reduction. In fact, the researchers found that ginger had the same effects as common pain relievers like ibuprofen.
Regardless of how or where, research consistently shows that ginger helps reduce nagging pain and soreness. There’s no reason not to include it in your diet, and we love getting an extra 1g (10g equivalent!) here in K1ngs Blood.
KSM-66Ⓡ∞ Ashwagandha Extract (made with certified organic ashwagandha) (Withania somnifera) (root) (standardized to minimum 5% total withanolides) – 600mg
Because K1ngs Blood was created to optimize your hormones, it needs some sort of defense against things that could disrupt harmonized levels. Otherwise, things like stress will initiate chaos-causing cortisol levels. Luckily, Olympus Labs has employed one of the best cortisol defenders we have in the popular adaptogenic herb, ashwagandha.
Balancing testosterone and cortisol
When cortisol levels get too high, your body produces less testosterone and burns less fat. In order to keep your testosterone where it should be, without necessarily boosting them, things like ashwagandha are an intriguing option.
A study published in 2012 showed that subjects suffering from chronic stress saw significantly reduced stress levels after consuming 600g of highly concentrated ashwagandha per day for 60 days. Infertile men have yielded testosterone gains by as much as 14-40% with ashwagandha, and another got 10-22%!
Even in healthy young men, which is what most Olympus Labs K1ngs Blood users will be, ashwagandha showed a 15% boost on its own! This is huge, as the ingredient has shown to work for nearly everyone.
K1ngs Blood packs the dose that works!
Most of the tests on ashwagandha that have been published use the 600mg dose that we see here. It’s the clinical dose, and all of the purported benefits of the plant are tied to it. We love seeing the clinical dose here, and have no doubts that you’ll feel less stressed.
In addition, KSM-66 is extremely well-studied, and has had zero reported serious complaints that we’re aware of. At this point a brand needs to make a pretty strong argument when using something other than KSM-66 ashwagandha for hormonal purposes.
Indole-3-Carbinol (I3C) – 400mg
Calling on the powers of multiple cruciferous vegetables, Indole-3-Carbinol has grown in popularity in recent years. Although its typically cited for its potential anti-cancer properties, there is some promise for its use in hormone balance, as well.
I3C has been shown to keep estrogen levels in balance, by either decreasing high levels or raising low levels. In small doses, some research has also shown that it can inhibit aromatase enzymes from converting testosterone into estrogen.
I3C doesn’t strictly lower estrogen levels. It helps maintain consistent levels, meaning it’s safe for use for both men and women looking to keep hormonal balance!
EuryGold™ (Eurycoma Longifolia) (Root) (Std. Extract to 28% Glycosaponins, 20% Polysaccharides) – 300mg
Eurycoma longifolia, also known as Tongkat Ali or Longjack, is commonly found in hormonal supplements. We’ll briefly talk about its benefits here, but feel free to check out our massive post on it — see our Tongkat Ali page!
Longjack is typically used to boost libido and virility.[16,17] In addition, it has also shown potential to balance testosterone levels. In fact, one study has even shown that Longjack may be as equally as effective as testosterone replacement therapy (TRT).
EuryGold™ seems to be relatively new to the supplement industry – it’s a standardized extracts that looks up to par with other options, so we’ll trust Olympus Labs’ judgement on this one!
PrimaVieⓇª (Shilajit Fulvic Acid Complex) – 200mg
Shilajit is growing in popularity in testosterone supplements, and it’s no surprise as to why. It has roots in ayurvedic tradition, which also happened to bring us ashwagandha. It also seems to work similarly to Longjack!
Shilajit works to keep testosterone levels elevated. It also has been shown to improve muscle pliability and recovery.
On a personal note, I anecdotally swear by this ingredient — I was using it when we conceived. Shilajit plays backup to Longjack here — they’re often paired together — and we love this reinforcement of hormonal balance!
Royal Jelly (3:1) Extract – 100mg
Royal jelly is a substance produced by honey bees to help feed queen bees (hence the name). You can typically find it sold for its use in treating chronic diseases, as it contains many different glycoproteins that have their individual reported benefits. But, we think it’s on this label for one specific reason, and like ginger, it has to do with the menstrual cycle.
While there is a lot of research on what royal jelly can do, there is only a small amount that revolves around the hormones, specifically. One study cites that postmenopausal women had reduction in back pain and anxiety, although these women ingested 800mg daily for 12 weeks. We have much less than that here, and combined with that fact that more research is needed regardless, we can’t really concluded that it plays a huge part in this product.
Cnidium monnieri extract [(fruit) 70% Osthole] – 80mg
We wouldn’t be truly breaking down an Olympus Labs supplement if we didn’t get to cover an ingredient that hails from Traditional Chinese Medicine!
Osthole is derived from the Cnidium monnieri plant, and have long been used for its supposed antiviral properties. But, Olympus Labs is sure to include it on this label, as research has shown that osthole may benefit both male and female hormonal function.
Osthole has been used as an erection-promoting herb in TCM, and some research exists to back it up. In vitro, it appears to promote erections, depending on dosage, through decreasing nitric oxide synthase inhibitor levels. Although this hasn’t been tested in humans yet, there does seem to be some potential.
One study has also shown that osthole increases testosterone and luteinizing hormone. However, this study was conducted using rats, and no further research exists.
Wanting to study osthole and its potential in treatment for menopause, scientists constructed a research model using mice. They found that osthole was sufficient in protecting against bone loss, showing potential in treating postmenopausal osteoporosis. However, these same researchers did note that they couldn’t find any other areas related to estrogen metabolism where osthole played a role.
Magnesium Aspartate (Providing 90mg Magnesium, 22.5% USRDA)
Olympus Labs always does a great job of helping to fill our dietary magnesium gap. This is one of the most prevalent deficiencies in the standard western diet, and always encourage users to check their diet to see how much they need to supplement.
When magnesium is deficient, testosterone production can be impaired, anxiety may rise, sleep quality can go down[32,33] (which in turn is bad for growth hormone, diet, testosterone, muscle-building, etc), and more. Don’t ignore this critical mineral!
90mg is a safe topper dose for your day, and welcome addition to any diet. If you’re severely deficient, you may need more, but if you get too much, you may end up in the bathroom.
Magnesium Aspartate is well-known since it’s the form used in “ZMA” formulas.
Zinc Bisglycinate Chelate (Providing 10mg Zinc, 66% USRDA)
Similar to the magnesium above, getting enough zinc can “rescue” many ailing functions you didn’t even know you were experiencing due to something so simple!
When you’re deficient, you can easily have lower testosterone, an impaired immune system, and a weakened libido. It even increases plasma IGF-1 when supplemented!
This is a chelated form, which we love because it increases absorption. Our small intestines do not absorb minerals that well, but they do absorb amino acids like glycine. So by binding the zinc to glycine, we effectively “Trojan horse” the zinc into our systems for better absorption!
The dosages above are for eight capsules — the daily dose. We suggest breaking this into two different 4-capsule doses, both taken at meals (roughly 12 hours apart if possible).
8am / 8pm is usually a good strategy.
Conclusion: K1ngs stay kings!
In true Olympus Labs style, we have a monstrously-loaded, clinically-dosed supplement that does not shy away from Chinese medicine. They take things we already like, and add even more, teaching us a few things along the way.
Truth be told, natural testosterone boosters are typically for guys over the age of 35, but this one’s to the point where we’re confident even young healthy guys are going to get at least a small bit of benefit too.
In K1ngs Blood, Olympus Labs is unleashing a versatile hormone optimizer. While most hormone-related supplements focus on either men or women, exclusively, K1ngs Blood doesn’t need to. Each ingredient has potential benefit to either sex, without inducing any peripheral drawbacks. That makes it safe to use if you want to revise your hormone levels, whether you’re male or female.
It also makes it extremely stackable! If you’re a man trying to “more aggressively” raise testosterone levels, this can be paired with something like Olympus Labs Ar1macare Pro. On the natural side, a stack with Olympus Labs Test1fy could be good, and to further protect on the estrogen end, Olympus Labs Elim1nate also supports hormonal balance.
If you want some help in keeping your hormones in check, and your body running as it should, make sure you have something like K1ngs Blood in your arsenal! Prices and Olympus Labs News Alerts are available below, courtesy PricePlow:
