@WowwyZowwy My rat's first NAD shot was buffered, and it was fine with a very minor sting. Second was my own supply (not realizing there was unbuffered) and it stung like a mother-f-er. Never again. So there is your answer as far as I'm concerned.
I'm just about to start SS-31, but anecdotes from other peptide forums is that it needs 4-8 weeks and you won't really know it's working. That said you need to do the Mots AFTER your cycle of SS-31 or you're just wasting it. You can run NAD alongside it however.
Also, I suspect the Reta is what is dragging you down, b/c at just 1.5mg it F's me up for a good 48 hours where I could just lay in bed if that was an option. It weens for me as the week goes on since I do weekly shots. I would also advise you dose down on the Reta. It's not about upping the dose, it's about finding that sweet spot and I'm very adamant about this. People have this inertia where they must dose up and get more benefits, but it doesn't work like that and is actually harmful plus you are just wasting product. Find the sweet spot and stay there.
