D-Serine

Relentless Improvement is an approved brand of nootropics from the Reddit nootropics approved vendor list. Their main problem is they often discontinue products, so I'm not sure how long this is going to be around.The form of serine usually found from other vendors is L-serine, which is **not** the natural form of serine present in the body and brain.D-Serine is the correct isomer of serine present in the body and brain, and it's unusual to be able to find it available from anyone. Relentless Improvement so far seems to be the only source, so get it while you can!

D-Serrine is a fascinating Nootropic, if you are concerned about NMDA receptor hypofunction and want to take steps towards remediating it. I hope the company keeps this in stock and ensures quality. I will keep buying in size!

Took my first dose today and I feel uplifted.😀

A a single capsule makes me sleep deeply with absolutely no grogginess the next morning. I have meaningful and enjoyable dreams. This is very simply the most effective sleep aid I have ever tried. Back ordered because of what I suppose must be high demand.

Not for me.

dont trust it

I plan to send off a couple of capsules to a lab to see what they contain. D-Serine is hard to find except as a powder which is hard to work with, so I'm glad I found this.
