What did @thetestosteroneconsultant actually say?
The creator claims that three days after drinking a homemade "natural testosterone shake," he woke up with morning erections "for the first time in a very long time." He then pivots to a framework: morning wood depends on testosterone, stress hormones, sleep quality, and nitric oxide levels. The shake, he says, "addresses all four factors," especially when taken post-workout. To get the recipe, you have to comment "shake" and receive a direct message, a classic lead-generation funnel.
It is worth naming what this actually is: a personal anecdote used to sell access to a guide. There is no ingredient list disclosed, no dosage, no peer review. The "three days later" claim is presented as evidence. It is not evidence. It is a story.
Does the science back this up?
The four-factor framework he describes is broadly consistent with physiology, even if the delivery is oversimplified. The claim that a single shake can meaningfully move all four variables simultaneously, especially within 72 hours, is not supported by any clinical literature.
Morning erections, technically called nocturnal penile tumescence (NPT), are driven by REM sleep cycles and are sensitive to testosterone levels, but the relationship is more complex than the video implies. Testosterone affects NPT threshold, but men with low-normal testosterone can still have regular morning erections. Seftel et al. (2004, Journal of Urology) found NPT is a useful but imperfect proxy for erectile function. Regarding nitric oxide: L-arginine and L-citrulline supplementation has shown modest effects on blood flow in some trials, but Cormio et al. (2011, Urology) found meaningful improvement only at 2.5g/day of oral L-citrulline, over weeks, not days. Cortisol suppressing testosterone is real physiology. Leproult and Van Cauter (2011, JAMA) confirmed that sleep restriction reduces testosterone. But a shake does not fix sleep.
What did they get wrong (or right)?
Credit where it is due: the four factors he names, testosterone, cortisol, sleep, and nitric oxide, are genuinely relevant to erectile function and morning erections. That part is defensible physiology, even if it is simplified for an Instagram audience.
What he got wrong, or at minimum wildly overstated, is the timeline and the mechanism. "Three days later" is not how nutritional interventions work at a biological level. Testosterone does not meaningfully rise from food or standard supplements in 72 hours. A meta-analysis by Bhasin et al. (2010, Journal of Clinical Endocrinology and Metabolism) makes clear that testosterone normalization from lifestyle interventions takes weeks to months, not days. The three-day anecdote is almost certainly a placebo response, regression to the mean, or sleep improvement from changing his routine, none of which are the shake. Attributing it to the shake is causal overreach. Also, gating the ingredient list behind a DM is a red flag. If the ingredients were just food, there would be no reason to withhold them.
What should you actually know?
Morning erections are a legitimate health signal. Regular NPT is associated with intact vascular and hormonal function, and a sudden or prolonged absence is worth discussing with a physician, not fixing with a shake recipe from Instagram DMs.
If your morning erections have disappeared or significantly declined, the appropriate next step is bloodwork: total testosterone, free testosterone, SHBG, LH, FSH, prolactin, and a metabolic panel. These tests exist precisely because the causes are many and the treatments differ. Low testosterone from primary hypogonadism is a different clinical picture from suppressed LH from stress or obesity, and neither is solved by a post-workout smoothie. The Sleep Foundation and multiple urological guidelines consistently point to sleep apnea as an underdiagnosed driver of both low testosterone and poor erectile function. A shake cannot treat sleep apnea. If you are chasing this kind of content because something feels off hormonally, that is a valid concern. It just deserves a real clinical evaluation, not a DM funnel.
