How can you know the size of your vial and how much vac water it can hold

Brand new and havent start my first peptide yet; still researching, lurking in groups, trying to learn and absorb as much as possible. There is so much conflicting data readily available. But I've landed here and feel safe, surrounded by knowledge and quality guidance. My first goal is to lose weight and increase energy so I've decided to try Reta. I'm also intrigued with KLOW because of the gut health and collagen benefits. I'm 58, my energy has tanked. I dont have significant food noise, fasting isnt an issue but it doesnt move the scale. I cant seem to find any information on how much time I should wait between adding an additional pep? IE if I begin with KLOW to build up gut health benefits before starting Reta, should I run a full 20 day cycle first? How long are you taking a pep before introducing a new one into your stack? I read that I'm throwing money away if I dont heal my mitochondria with SS-31 first. Is there any validity to that? Sorry for the essay, I promise I'm trying to research before reaching out for help.

At the end of the registration. It ask for Tax ID /EIN #. I don’t have one at this time so I can’t complete my registration. Is this normal for this site?
