If you can pay with a credit card you're paying too much. This might be worth it if you just want to see if peptides are for you but make sure that when you buy you're buying what's known as a 'kit', which is typically 10 vials of the peptide. The vendors that show up in ads on Facebook/Reddit/TikTok and at the top of google search are selling you a single vial for the price of a kit
Don't buy direct from China, but if you're not dealing with a chink you're paying too much. Look for someone who only operates via Telegram and/or Discord and has a US warehouse that they ship from. You'll likely email them to set up the order manually and receive responses in the middle of the night
The reason you want a US warehouse over direct from china despite it being slightly more expensive, on top of faster shipping and no chance of seizure, is that if you get seized you might lose TSA pre-check and/or Global Entry if you're signed up for those services
If the vendor DMs you first it's a scammer, you will 100% receive friend requests/DMs from impersonators when you join their discord/TG
You'll need crypto. Make sure you know the basics like how to send coins on the various networks because if you do it wrong there's no way to fix it. Don't send direct from an exchange or you might lose your exchange account, you'll basically need to do it the way you do to send crypto to the farms where you go through an intermediate personal wallet like Exodus etc.
You want a vendor who has Janoshik results, and ideally a vendor that sells enough volume that there are 3rd party testing groups also testing their peptides just to keep them honest. Alternatively, you can sacrifice one vial from your kit and send it to Janoshik yourself, the testing is $300 which is probably more than you'll pay for the kit which is why testing groups are so valuable.
If you can't get syringes without a prescription in your state you can still get veterinary syringes on Amazon. Alternatively you can shop around and find a diabetes supplier who just doesn't give a shit and will send you diabetes syringes regardless of the law. Easy Touch and BH Supplies are both good and available on amazon. 31 gauge needles hurt less but if you're fat-fingered they're easy to bend. 29 gauge 3/8" or 5/16" are plenty comfortable, I do use 31 gauge/5/16" myself without much trouble. You can buy them in .3ml, .5ml, and 1ml, no real reason not to buy 1ml since they're all the same price
You'll also need bacteriostatic water, Hospira is the gold standard. Technically this is another prescription-only thing in a lot of places but none of the places that sell it seem to care. Peptidetest is probably the best place to buy it. Don't buy research bac water on amazon it's mostly untreated tapwater. Lambda is ok-ish if you just refuse to source Hospira, the rest are trash. If you search Hospira on Amazon you'll get bootleg imitation Hospira that I haven't seen tested but it's very likely garbage. Hospira seems expensive but when you realize how little you actually need of it you'll realize it's worth the small premium over the cheaper alternatives
In addition to the diabetes syringes I mentioned, they're not necessary but I also have some beefy 3ml 23gauge/1" needles for reconstitution. The vials are vacuum sealed and 3ml, the vacuum seal makes it very hard to draw a shot if you don't add air, so I like to draw the amount of water I need, then fill the rest of the syringe with air, and shoot that in all at once, then shoot in additional air prior to drawing each shot. You could do your shots with these but most peptides want to be injected into fat tissue and if you're slim enough 1" might be too long, not to mention 23g needles are way thicker than 29-31g and can cause bleeding/bruising
