Very interesting study, not only because of the obvious social implications, but also because it confirms the anabolic effects of the vitamin D/K combination, as well as the likely androgenic effects of vitamin D.
Another interesting finding from the study below shows, that the length and thickness are increased - a reliable sign of the androgenic effects of the vitamin D/K combination, which are also confirmed by the patients' increased libido and sense of vitality.
I believe vitamin K also has androgenic effects, given the changes it causes in men's jaws. If higher doses were used (the study used 100 micrograms daily) then the effects would be much more pronounced. The only drawback of this study is that the daily dose of vitamin D used was quite high (50,000 IU). However, the authors are well aware of the risks of hypercalcaemia and carefully monitor their patients, but fortunately have not noticed such side effects. The duration of treatment is 3-6 months.
Personally, I would prefer a vitamin D dose of around 5000 IU per day and a higher dose of vitamin K2 (MK-4) in the range of 10 mg-15 mg per day, as shown in the muscle anabolism study above. In fact, according to the same study , a low K2 dose of about 1mg might be considered sufficient. However, I've read a number of other studies on humans with vitamin K2 (MK-4) and they all claim that the benefits to bone, muscle and brain are probably increased by at least a 5 mg daily dose, and, given that vitamin K2 (MK-4)really has no known drawbacks (other than cost), I think that trying 10 mg-15 mg daily may accelerate the onset of the “ benefits“ mentioned in the study below.
I just took a dose of this combination using our products Calcirol (D3) и Kuinon (K2, MK4). Incidentally, it may be even more effective if the D/K combination is used topically (on the penis) as this may improve the effectiveness and accordingly lower the risk of side effects from D3 (hypercalcemia).

“...Fourteen male friends were invited to participate in a research project. They signed an informed consent form which explained the project and agreed to have blood drawn initially and whenever possible at 3 and 6 months after taking daily 50,000 units of D 3 and 100 mcg of vitamin K2. K2 is generally considered to be synergistic with D3 in enhancing deposits of calcium into bone. They were instructed to take no calcium supplements while on the D 3. They also agreed to have the senior author measure their flaccid stretched penis or to provide digital photos showing length and circumference of their erect penis initially and at 3 and 6 months.”
“...The two earlier studies, which demonstrated penis enlargement,5,6 used vacuum pumps that required 30 minutes of daily vacuum pumping to achieve enlargement of up to 1 inch in length (average 0.67 inches) up to 0.75 inches in circumference (average 0.55 inches). Interestingly, it is reported that surgical enhancement results in only 1-2 cm increase in length and 2.5 cm augmentation in circumference! [7]. In the current study, average increase in length of 0.46 inches and circumference of 0.523 inches is highly statistically significant and approximately equal to that obtained with vacuum pumps or surgical augmentation.”
“…The only known risk of large doses of vitamin D3 is excessive blood calcium levels with potential kidney damage. For that reason, individuals taking the large dosage of D3 are advised to avoid calcium supplements. In this current study, serum calcium levels at 3 and 6 months were all within the normal range. The physiological explanation for apparent androgenic effects of vitamin D3 are not simple, although plasma levels of vitamin D metabolites have been reported to have an effect upon sexual maturation and growth.11 There is some evidence that vitamin D3 is an androgen agonist and binds to Androgen Receptors.12,13 Much further work will be needed to explore this as a possible mechanism for enhanced penis augmentation with vitamin D.”
