Semaglutide aka sema- Ozempic or Wegovy active ingredient
Tirzepatide aka tirz- Zepbound or Mounjaro active ingredient
There are other options too, and other peptides, but don't touch them without way more research than just my dinky little thread. You're here because you're getting away from compounding, stick with what you know. Baby steps.
You're going to need bacteriostatic (bac) water, syringes, and your active ingredients. You may also want to filter. I don't filter, so I'm no help there, sorry.
Some people discussed it here but I will be zero help.
Bac water- Get Hospira brand. You're saving thousands of dollars, just get the good stuff so you don't have to worry about sterility or whatever.
Hospira Thread. Bac water is technically only good for a month after puncturing the vial, and is stored at room temperature in the dark. If you want to use it longer, that's on you. Yes, you'll throw out a lot. It's cheap anyway.
Syringes- There are many options, and lots of people have opinions. Some people like to get refillable pens. Personally, I use 1ml 30 gague 5/16 inch insulin syringes and they work perfectly fine and are cheap. I just get the generic ones off Amazon. Make sure you look into your local laws for syringe disposal, don't risk some poor sanitation worker getting stabbed with your old needles, that's gross and inconsiderate.
Someone recently shared this link to a free disposal container for sharps.
The Good Stuff:
Vendors
Don't assume a vendor is safe or good just because they've posted an advertisement here.
Take a look at the available sales. Look at what payment methods they accept- a few take credit cards, not many. You're probably going to have to use PayPal (not a good idea, PayPal can ban you for any or no reason), Alibaba, bank transfer, or cryptocurrency. Then use the search bar to see what people have to say about the vendor you're interested in. We're very opinionated here, you'll probably find a lot. No one is going to tell you "buy from this one!" because this is grey market, they've all got plus sides and down sides and have pretty much all had some sort of scandal. Do your own searches and decide which risks you're willing to take. Never be the first person to buy from a new vendor. Don't buy if the product isn't being tested unless you plan to test yourself. Consider sending your own product in for testing (janoshik is gold standard but there are others) but if not, make sure you're buying from someone that other people post the results from, or join a group buy where you all buy from the same batch and send something in to be tested together. Don't just blindly trust the tests posted by a vendor, they could be from a different batch, they could be photo shopped. This is your health we're talking about here. Vendors come and go, don't trust they have your best interest at heart no matter how many times they call you honey or dear or how hot their profile picture is. This thread discusses crypto. Some domestic sellers take credit cards, but you will pay a premium for that convenience. It's still much cheaper than name brand or compound.
Note: if you're buying from overseas, it can take weeks to arrive. You won't always get a tracking number. This is also normal.
