By the way, why did you bought 2 types of vitamin K2 + K1? In the study they used only mention K2.

I've read some of Shealy's stuff, and he does know a lot about natural health, etc. The guy is in his 80s and looks freakin great. But I strongly suspect this has to be bullshit for the following reasons: 1. If something sounds way too good to be true, it usually isn't. Average gain of 0.5" Girth from vitamins? One guy gained over an Inch in Girth? Really?? 2. There is no way a successful study of this magnitude, done in 2009, would not have been followed up or replicated. It just does not make sense. 3. Shealy wrote a paper in 1995 that references another paper by Brian Richards on "the Chartham method" paper... remember this being discussed on thunders and pegym ... its basically jelquing and pumping...again, never replicated, results sound too good... I figured 10 years ago that was also BS. In fact, I even tried it! (ps..dont ever jelq). If anyone wants to wager 10K USD that this will never be replicated, with a timeframe of 5 years. let me know... I accept paypal, lol.

It found that only 37 people had levels above 100 ng/ml (250 nmol/l). Only one person had true toxicity, at 364 ng/ml (899 nmol/l) (![8)](https://www.j4.phalloboards.info/media/kunena/emoticons/2.png "8)").In one case study, a woman had a level of 476 ng/ml (1,171 nmol/l) after taking a supplement that gave her 186,900 IU of vitamin D3 per day for two months (9).This was a whopping 47 times the generally recommended safe upper limit of 4,000 IU per day.The woman was admitted to the hospital after she experienced fatigue, forgetfulness, nausea, vomiting, slurred speech and other symptoms (9).Although only extremely large doses can cause toxicity so rapidly, even strong supporters of these supplements recommend an upper limit of 10,000 IU per day (3). > > A daily intake ranging from 40,000'100,000 IU (1000'2500 micrograms), for one to several months, has been shown to cause toxicity in humans (14, 18, 19, 20, 21).
