I wanted to share this report with the community. It relates to MT-1 (aka Melanotan-1, Afamelanotide) and its effect on the cardiovascular system. I discussed it at length with Anthropic and decided it was interesting enough that maybe others would like to see. The subject matter is how MT-1 may protect the vascular system from atherosclerosis. And no, this is not the entire work of an AI engine, but I did use Anthropic to discuss, analyze, and to produce a tight legible report. I will attach the .pdf for those interested.

Abstract

Activation of the Melanocortin 1 Receptor (MC1R) has emerged as a potential protective mechanism in the development and progression of atherosclerosis. MC1R signaling regulates macrophage lipid handling, inflammatory signaling, endothelial function, and plaque composition. Experimental evidence demonstrates that MC1R activation reduces foam cell formation, enhances reverse cholesterol transport, stabilizes atherosclerotic plaques, and improves vascular biology. Synthetic agonists such as Afamelanotide — also known as Melanotan-I (MT-1) or NDP-MSH — mimic endogenous melanocortin peptides and may amplify these protective pathways. Although current evidence is largely derived from mechanistic studies and animal models, the biological framework suggests MC1R agonism could represent a disease-modifying strategy for atherosclerosis.

Would the same thing apply to MT-2?
That's a good question. From what I know, MT2 is more promiscuous than MT1, meaning it affects more Melanocortin 1 Receptors than MT1 does, notably MC4R. I believe MT2 is also harder on your cardiovascular parameters, BP, HR, than MT1. I just ran the question thru an AI because I didn't want to guess at anything else:

kinda what i wrote down. EDIT: I notice no MC3R activity from MT1 but I think that's wrong.

If you are after the cardiovascular benefits, I'd stick to MT-1.
 
I should add to this writeup as well. MT-1 should also activate AMPK and downregulate mTORc.

I've attached a figure for it all. This is really something novel (to me at least).

Do you guys want me to add the writeup for this?

Knock yourself out. Blind us with science. I even like some bro science with a Freudian analysis, haha.

Have you also looked into the supplement natto? I take that now, along with vitamin K2 (MK7). But I am overdue to try my MT1.

Glad to see MT1 has more benefits than I thought. There is also some overlap with all of the melanocortin receptors (MC1R through MC5R), including with using setmelanotide and PT-141.

yes, nattokinase, I have some, but i dropped it because I'm on a very heavy supplement stack. Here it is. I do use K2 with vit D. I wish I noted the brand that used 5000 iu vitD and 200 K2, someone posted and I wasn't paying attention.

Is this the same natto that Chopped likes to throw in the basket to fuck with people? Its a fermented soybean paste that looks disgusting and apparently smells awful.

It tastes yummy, especially in rice balls. Though it has the texture of something some people might not care for.
