Very satisfied with the quality!
review by Tobias on 6/21/2019
I've ordered L-Serine capsules to prevent Alzheimer (the research is still speculative but given that there is no adverse effect of L-Serine, it appears to be a no-regret move to take it prophylactically). My internet search came up with Jo Mar Labs as the second-cheapest provider. The first provider I tried (the cheapest one) had very bad quality (some capsules were only partially filled, other capsules were broken). The capsules I've received from Jo Mar Labs, by contrast, didn't have any issues - they were all intact, clean, and reliably filled with a white powder that I trust to be L-Serine! :) I plan to update this review in about 40 years indicating whether the capsules also have succeeded in keeping Alzheimer away from me... ;)
