There are two forms of 1,4 andro that Bulk sells: one is a dione and the other a diol. How do they differ and for what purposes is each better suited? It seems the FAQ section refers to the dione in the recommended stacks; am I correct in this? Also, my understanding is that 1,4 andro is extracted from cow feces. Now, I have no problem with this in principle but I am concerned about the possible transmission of bse because the lower intestine of cows along with their nervous tissue can harbor the pathogen. Is there anything that is done in the manufacturing process to ensure that the cattle are free of disease or to ensure that the prohormone itself is not contaminated?

Well, I've been reading about the upcoming ban. It looks all but certain. For those of us who wish to stockpile PHs could you recommend the best ones and the best methods to do this. Man, I feel like I'm talking about a preban assault rifle magazine! This is so ridiculous but then again those preban firearm parts are desirable now. Thanks for your help.

The dione is probably preferable since it has established positive feedback and doesn't have many estrogenic effects to begin with.

1,4-andro is not extracted from cow feces. It appears in cow feces when the cows are fed progesterone, but the 1,4-andro you find in supplements is synthesized.

My recommendation for stocking up is to buy bulk powders, vacuum sealed.

OK thanks for the info. Who says synthetic is never better than natural.
