Anxious and Told You're Fine? Peptides for Mental Support
from Med Matrix Method · host Med Matrix
Cognitive peptides have become one of the loudest conversations in the nootropic and longevity space, and one of the least understood. Dr. Sasha Rose and Colin Renaud, PA-C talk through Selank and Semax: what they are, what the research has actually evaluated, and where the honest limits sit.Colin is careful with the evidence. Much of what exists is laboratory and animal work. Some human trials were conducted in Russia. Semax only recently entered the FDA compounding conversation when the Pharmacy Compounding Advisory Committee discussed Semax-related substances. Animal data on BDNF is a reason to study something, not proof that it works in people.Dr. Rose keeps returning to the foundation underneath any of it. Sleep, nutrients, blood sugar, inflammation and stress physiology. B12, folate, iron, vitamin D and thiamine, and what they have to do with fatigue and cognition. Both are direct that none of this replaces psychiatric care, and that someone already on psychiatric medication needs their prescribing provider in the conversation.For educational purposes only. Not medical or psychiatric advice. Selank and Semax are not FDA approved in the United States. If you are experiencing thoughts of self-harm or symptoms that feel unsafe, seek urgent help. In the US, call or text 988.
