@chasvitalityrx's free testosterone claims, fact-checked
Quick answer
The creator promotes boron supplementation and lifestyle changes as a strategy to lower SHBG and increase free testosterone bioavailability, framing this as an alternative to TRT. The SHBG-testosterone binding physiology is accurately described, and the referenced Naghii et al. (2011) boron study is legitimate but based on only eight participants. Men experiencing symptoms of low testosterone with borderline total levels should have free testosterone and SHBG measured clinically, as elevated SHBG can have underlying causes that supplements will not address.
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 @chasvitalityrx actually say?
The creator's core argument is that most men are obsessing over total testosterone while ignoring free testosterone, and that SHBG is the real villain. They claim "only 1 to 3% of your testosterone is actually free and working" and that a 10mg daily boron supplement can "reduce SHBG by 10% within hours." They also stack in vitamin D at 5,000 IU, compound lifting, meditation, and sleep as a non-injection protocol for feeling hormonal benefits without touching total T numbers. The pitch is framed as a smarter alternative to TRT.
To their credit, they at least promised a study link. Whether that link actually appeared is a different question.
Does the science back this up?
Partially, yes. The boron claim has real, if limited, evidence behind it. But "within hours" and "10%" are doing a lot of heavy lifting in that sentence, and the research is thinner than the creator implies.
The most-cited study here is Naghii et al. (2011, Journal of Trace Elements in Medicine and Biology), which found that men supplementing with 10mg of boron daily for one week showed a significant reduction in SHBG and an increase in free testosterone. The "within hours" angle likely refers to the same paper's acute measurement at 6 hours post-dose, where free testosterone rose and SHBG declined. Those results are real. But the sample size was eight men. Eight. That's not a clinical trial, that's a pilot study. The effect size and the mechanism still need replication in larger, controlled populations before anyone should be telling half a million TikTok viewers this "actually works."
The 1-3% free testosterone figure is accurate. Roughly 2% of circulating testosterone is unbound, with the remainder split between SHBG-bound (roughly 44-65%) and albumin-bound (30-54%), per Vermeulen et al. (1999, Journal of Clinical Endocrinology and Metabolism).
What did they get wrong (or right)?
They got the physiology directionally right. SHBG does bind testosterone and render a significant portion biologically inactive. Free testosterone is a more clinically meaningful number for symptom correlation in many cases, and this point is genuinely underappreciated in online testosterone discourse.
What they got wrong: the certainty. Saying boron "actually works" as a "hack" based on one eight-person pilot study is irresponsible framing. The creator says "I'll put the study link in the captions so don't at me" as if a single citation ends the debate. It doesn't. The Naghii study is real science, but it's preliminary science.
The vitamin D recommendation also has some support. Low vitamin D is associated with lower testosterone and higher SHBG in observational data (Pilz et al., 2011, Hormone and Metabolic Research), but supplementation trials haven't consistently shown dramatic free testosterone increases in men who aren't severely deficient. The dose they mention (5,000 IU daily) is above standard recommendations and could cause toxicity in some individuals over time. That deserves a caveat they didn't give.
The compound lifting and sleep advice? Solid. No argument there.
What should you actually know?
Free testosterone matters, and your doctor may not be checking it. If you're symptomatic, ask for a full panel that includes free testosterone, SHBG, LH, and FSH, not just total testosterone. A high total T with high SHBG can still leave you feeling terrible.
Boron supplementation is low-risk at 10mg and may have a modest SHBG-lowering effect, but you should treat it as a preliminary finding, not a proven protocol. The evidence base is a single small pilot study. If that gets replicated in a proper RCT, the story changes. It hasn't yet.
More importantly: if your SHBG is genuinely elevated and your free testosterone is low, that's a clinical finding worth investigating with a provider. There are identifiable causes, including thyroid dysfunction, liver disease, and certain medications, that won't respond to boron. Treating a symptom cluster with supplements while an underlying condition goes undiagnosed is not a "hack." It's a delay.
The framing of this as a TRT alternative is where things get genuinely misleading. For men with clinical hypogonadism, lifestyle optimization and boron supplementation are not equivalent to hormone therapy. They're not in the same category.
Bottom line
This video is better than most testosterone content on TikTok. The SHBG explanation is accurate, the boron citation is real, and the lifestyle advice is reasonable. But the confidence level is set about three notches higher than the evidence warrants. Know the difference between a promising pilot study and a proven protocol before you restructure your supplement stack around it.

What it helps with
- The creator promotes boron supplementation and lifestyle changes as a strategy to lower SHBG and increase free testosterone bioavailability, framing this as an alternative to TRT. The SHBG-testosterone binding physiology is accurately described, and the referenced Naghii et al. (2011) boron study is legitimate but based on only eight participants. Men experiencing symptoms of low testosterone with borderline total levels should have free testosterone and SHBG measured clinically, as elevated SHBG can have underlying causes that supplements will not address.
- Roughly 2% of circulating testosterone is free and biologically active; the rest is bound to SHBG or albumin (Vermeulen et al., 1999, JCEM).
- Naghii et al. (2011) found 10mg daily boron reduced SHBG and increased free testosterone, but the entire study population was 8 men, making broad recommendations premature.
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.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

- Roughly 2% of circulating testosterone is free and biologically active; the rest is bound to SHBG or albumin (Vermeulen et al., 1999, JCEM).
- Naghii et al. (2011) found 10mg daily boron reduced SHBG and increased free testosterone, but the entire study population was 8 men, making broad recommendations premature.
- Elevated SHBG can result from thyroid dysfunction, liver disease, or certain medications, conditions that will not respond to boron or vitamin D supplementation.
- Vitamin D deficiency is associated with lower testosterone in observational studies, but supplementation in non-deficient men has not consistently produced measurable free testosterone increases in RCT data.
- A standard testosterone blood panel often reports only total testosterone; if you are symptomatic, ask your provider specifically for free testosterone and SHBG measurements.
- Compound resistance training is one of the better-supported lifestyle interventions for modestly reducing SHBG, with multiple studies showing acute and chronic effects on hormone binding proteins.
- Framing boron supplementation as a TRT alternative is clinically inaccurate; for men with diagnosed hypogonadism, the two are not interchangeable and that conflation can delay appropriate care.
