We got a trusty source for pharma grade pure beta lapachone (>98%) such the one used in the korean studies. The price is 250$ per gram. This is the very best price we got so far. If anyone found a better price, please contact us, but the source has to be reliable such the one we will use.
Knowing beta-lapachone has the half-life is beyond 24 hours, we can consider a low dose such as 50mg (also considering the HED) per day could be enough to get significant result from increasing energy, body fat loss / healthy weight (very interesting effect to monitor) and slowing aging.
If anyone is interested we can group buy it, but should ask for 10g production at least to get this price. If anyone is interested, please consider let a comment below.
Thank you !
