A few of us in my family recently tried a research compound. Two also added a second peptide, two others a different combo, mixing in NAD+ throughout. Not much before-and-after difference noticed. Reactions to NAD+ varied from nothing to mild chest stimulation for a few minutes. Weeks later, took the same amount again yesterday, felt within seconds an adrenaline-like chest sensation that intensified fast and spread through my whole body. Genuinely strong. Had to sit down, worried I might pass out. Hands tingly, lightheaded. Faded after about a minute. Told another family member, who said he and a fourth person went through something similar. The second person tried less next morning, comparable reaction despite feeling nothing before, described as almost out-of-body.
