Both companies closed their doors due to sourcing issues..which is unfortunate.

However, I have a new source for all the products those two companies provided called Amino Asylum.
Here is a link to the review I did on them:

Yes. Science.bio has the best quality I’ve found.

Here is a link to their Nootropics

My first order was on September 2018 from Amazon where it had 92% lab test in the review field. This year on January I looked directly to their website as Amazon banned selling Sarms and it has still same effects. Currently using S4 and GW. It is very rare to find a company who is selling legit sarms in pills.

Yes, you need to check out optimizedpeptides.com

This is the only American made amino-peptide company that does 3rd party testing on every single batch of product and publishes the HPCL/purity testing for customers view before buying. I actually did a whole article on TB-500 not too long ago which I mentioned using Optimized Peptides product as my go-to source.

You can see my TB-500 article where I reviewed their product here (there is also a coupon later in the article too):

Their peptides look pretty good but I do not have any experience with their products
