Hiya hun! I also welcome you, and agree with bisco and sour, read a lot and, if you are able, donate as there is definitely a lot more info available in special donor sections. I have been both a plain member and a donor on and off over a few years at least, I lurk a lot as I am pretty shy about involvement... but recently have been trying to do more, contribute more.
It is pretty user friendly, but new posting folks have to cautious not to stray off topic, or ask questions before at least trying to search something themselves. Veterans here do understandably get frustrated when it comes to these areas.... once you have been around a little bit in terms of posting, likeable content etc, there seems to be a little bit more flexibility though.
Read up on payment options, you being in the UK, may have a few different options than those in the U.S.... especially with the European sources. Bitcoin seem to be a favorite, and there are several great options for super good meds from EU to UK. that use payment methods specific to your area.
When you do decide to order, make sure to check the thread for that particular vendor right before you place the order to be sure everything is still going well with the vendor. I have made the mistake of just placing an order with a previously used vendor, only to find out later problems have been occurring, or there is a foreign holiday I was not aware of.
If you don't see something you need, ask a vendor if they have access to your requested item. I have had a vendor help me multiple times this way. You can also use the search bar to look for info on your particular requested item.
Do be cautious about typing actual full names of a med in the forum, especially if it is a sensitive subject or item. This helps keep things on the "down low" so to speak. Non controlled meds seem to be ok to be more candid about, but for sensitive words, many posters will slightly disguise, like "m0rph€€n". The only problem with doing this, is it does makes it hard for a newbie to search a particular substance... I don't really know a way around this, except to simply take time to really read and poke around bf asking outright.
Online pharmaceutical is a huge world, there are tons of scams out there though, so always run a source through here first. I'm not saying there are not good sources out there that are not listed here, but if your just getting your sea legs with pharmacies, it is best to stick with a source that can be vetted. If you have a source you want to try, but don't see it here, just message admin and tell them about it. Ask if you may post a question about it, and where it would be appropriate to ask about an un-vetted source.
Hope these tips help! Super glad you popped in!
