- 0:00There is a way to naturally increase your testosterone levels up to 700%
- 0:04with all the cost of any supplements or gym memberships.
- 0:07Make sure you watch until the end, as I'll be showing you exactly how to do this.
- 0:10Competition makes testosterone levels go through the roof.
- 0:13It is a single factor that increases testosterone levels more than anything else.
- 0:18More than lifting weights, more than supplements.
- 0:20Competition is hands down the greatest testosterone producer.
- 0:24Now this doesn't have to be physical competition, it would be mental competition.
- 0:27Anything that requires you defending your status or increasing your status
- 0:32will lead your testosterone levels going up.
- 0:34Now, there was a study in which six high level chest players were observed
- 0:38while competing against each other, and their testosterone levels were measured.
- 0:42And the results of this study were very, very interesting.
- 0:44Each time a player had to defend his status via playing a game of chess,
- 0:48his testosterone levels were rocketed going up on average 150%, which is a huge amount.
- 0:54But one of the six players had a testosterone increase of 600% potentially even higher than this.
- 1:00I'm going to stop you there.
- 1:03I know the study you're referring to.
- 1:04Challenging the top player a preliminary study on testosterone
- 1:07responds to an official chess tournament.
- 1:10And like he said, there were increases in testosterone.
- 1:12But this is what they looked like.
- 1:15Oh cool, the lines are all going up.
- 1:17But do you see this little number right here?
- 1:20Do you see what that is?
- 1:21That's a 250.
- 1:22Four of those players were below 250 at the start.
- 1:25Do you know what that means?
- 1:26Four of these players were hypogonatal.
- 1:28That means their testosterone didn't work properly in the first place.
- 1:31And I'm going to take a minor stab and say that these people don't just play chess once in a while.
- 1:35So if playing chess consistently raised your testosterone levels,
- 1:39why on earth are they hypogonatal?
- 1:41I'll tell you why, because testosterone raises in the context of competition,
- 1:45do not last.
- 1:46And the cute responses in testosterone do not make a difference in the long run
- 1:50to your overall testosterone levels.
- 1:52Stop listening to these entrepreneurial success gurus who couldn't understand a piece of literature
- 1:56if it slapped them in the face when they tell you that you can raise your testosterone levels by 600%.
- 2:01It's not happening.
- 2:02At least not in any meaningful context that is going to be helpful to you in any way.
- 2:06If you can't understand a study, you shouldn't be talking about it.

Can you naturally boost testosterone? What TikTok gets wrong
Quick answer
The video accurately identifies that acute testosterone elevations from competition are transient and do not reflect changes in baseline testosterone, which is the clinically relevant measure for evaluating hypogonadism. Four of the six chess players in the referenced study appear to have had total testosterone below 250 ng/dL, consistent with possible hypogonadism, though a single measurement cannot confirm diagnosis per Endocrine Society criteria. Anyone experiencing symptoms of low testosterone should seek a formal clinical evaluation rather than relying on lifestyle interventions promoted on social media.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "Can you naturally boost testosterone? What TikTok gets wrong" from TNF. We read the clip as a TRT social video fact-checks claim about Testosterone, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: The video accurately identifies that acute testosterone elevations from competition are transient and do not reflect changes in baseline testosterone, which is the clinically relevant measure for evaluating hypogonadism.
The reason this review is not generic is the source wording and the canonical claim label "trt replying to y2hrn increase your test levels greenscreenvideo." In this clip, the useful excerpt is: "There is a way to naturally increase your testosterone levels up to 700% with all the cost of any supplements or gym memberships." That wording changes the review because it points to Testosterone evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Cardiovascular Safety of Testosterone-Replacement Therapy (2023), Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline (2010), and Functional testosterone deficiency in aging men: Clinical impact, diagnostic pathways, and treatment strategies (2026), plus the creator's own wording. Testosterone decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What it helps with
- The video accurately identifies that acute testosterone elevations from competition are transient and do not reflect changes in baseline testosterone, which is the clinically relevant measure for evaluating hypogonadism. Four of the six chess players in the referenced study appear to have had total testosterone below 250 ng/dL, consistent with possible hypogonadism, though a single measurement cannot confirm diagnosis per Endocrine Society criteria. Anyone experiencing symptoms of low testosterone should seek a formal clinical evaluation rather than relying on lifestyle interventions promoted on social media.
- Geniole et al. (2017, Hormones and Behavior) analyzed 45 studies and confirmed competition produces a real but short-lived testosterone rise, typically resolving within 60 to 90 minutes.
- No peer-reviewed evidence shows repeated competitive activity raises baseline total or free testosterone in healthy or hypogonadal men over the long term.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.

Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @t_nutrition_fitness actually say?
The video opens with a bold claim from another creator: competition can raise testosterone "up to 700%" with no supplements or gym fees required. The original creator cites a chess tournament study showing players' testosterone rose an average of 150%, with one player hitting 600%. Then @t_nutrition_fitness steps in to fact-check it, and honestly, the rebuttal is sharper than most of what you see in this space.
The debunker's core argument is this: four of the six chess players in the study started with testosterone below 250 ng/dL, which is clinically low. His point lands. If competitive chess consistently elevated testosterone in any meaningful way, regular players wouldn't be walking around hypogonadal. He wraps up by calling out "entrepreneurial success gurus" who misread studies, then plugs a home testing service with a discount code.
Does the science back this up?
Yes, mostly. Acute testosterone responses to competition are real and well-documented, but they are transient. They do not restructure your baseline hormonal profile.
The study referenced appears to be Mazur et al. (1992, Hormones and Behavior), which examined testosterone responses in competitive chess players. That and related work from Booth et al. (1989, Psychosomatic Medicine) confirm that winning a competition, or even anticipating one, can produce short-lived testosterone elevations. A meta-analysis by Geniole et al. (2017, Hormones and Behavior) reviewed 45 studies and found a consistent but modest "winner effect" on testosterone. The effect is real. It is also temporary, typically resolving within 60 to 90 minutes post-competition. There is no peer-reviewed evidence that repeated competitive activity translates into sustained increases in baseline free or total testosterone in healthy or hypogonadal men.
What did they get wrong (or right)?
@t_nutrition_fitness gets the main point right, and deserves credit for reading the actual data rather than the headline. The observation that four players had baseline testosterone below 250 ng/dL is a genuinely important catch that undermines the original creator's argument at its foundation.
That said, a few things are worth flagging. First, the "700%" figure in the title and the "600%" figure in the chess study are not the same claim, and conflating them muddies the rebuttal slightly. Second, while hypogonadism in the chess players is a reasonable inference from the data shown, we should be careful: a single morning measurement is not a clinical diagnosis of hypogonadism. The Endocrine Society guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism) require two separate fasting morning measurements below 300 ng/dL plus symptoms before a diagnosis is made. The debunker is probably right, but "hypogonatal" as a definitive label from one data point is a slight overreach. The overall conclusion, that competition-driven testosterone spikes don't meaningfully raise your long-term levels, is solid.
What should you actually know?
Testosterone levels fluctuate constantly in response to sleep, stress, diet, physical activity, and yes, competition. None of those acute fluctuations are the same as raising your set point. Think of it like body temperature spiking after exercise. The spike is real; it doesn't mean you now run hotter permanently.
If you have symptoms of low testosterone, such as fatigue, reduced libido, loss of muscle mass, or mood changes, the right move is not to play more chess. It is to get a proper blood panel done, ideally total testosterone, free testosterone, LH, FSH, and SHBG, on two separate mornings. Home testing kits like the one plugged at the end of the video can be a reasonable starting point for awareness, but they are not a substitute for clinical evaluation. A FormBlends-affiliated clinician can review your full hormone panel and discuss whether any intervention is appropriate for your specific situation.
- Acute competition raises testosterone temporarily, but does not change baseline levels.
- The chess study data was misread by the original creator and correctly challenged by @t_nutrition_fitness.
- Suspected hypogonadism requires clinical confirmation, not a single data point.
