Listen what you obviously miss by all these posts is nobody cares for your word because you are not selling a song but steroids... people request analytical data only. How do you figure 99.2% purity? Have you tested and can you present us these results? If the cost of free samples is not a problem for you I am sure lab testing must not be either. Knowing also your address is public, can you post a picture of your facility?
Now on the subject of pricing I believe your operating model is eliminated the middle man (distributor) and prices are perhaps acceptable. Knowing how cheap bulk raw powder is looks like you can still be profitable. But still, it's not so hard for people to come up with an idea to make/sell own brew hence how UGLs pop. For all we know all your products could have been made with the same raw material any child on reddit can get.
All in all your approach of convincing people how altruistic you are is a waste if no concrete proof of your quality can be presented.
