Hi Michael - Welcome to Pherotalk. 
Yes, delivery to Europe is excellent and there are quite a few of us on this side of the pond.
Also, AD’s delivery is one of the very best - I can only think of one other company that can match its speed and reliability to the UK - and its even better than many UK/EU sellers, who can take weeks. DHL is also far less likely to be hit by a customs charge than any other firm, so the cost of delivery is often cheaper than it initially looks. 
Where to start - Yes, P75 is an interesting product but I really wouldn’t suggest to a beginner. All the Putatives, MX’s and Experimones are experimental products that are sold without warranty on the understanding that their properties are still under evaluation and not proven.
And P75 is one of the more unpredictable ones - for starters it is difficult to use and dose without moderation from more social pheros and if you overdo it, you can get very edgy/uncomfortable responses. It is also best in a low dose, without monumental quantities of other products (eg IO or MX297) to soften its hit.
You would be far better to look at the consumer line to start off with - these are far better understood and tested products that give reliable results and are sold with an excellent warranty, should you find them unusable.
Ammo is good - an all round social/sexy/masculine vibe that is usable in most situations.
TUTH - A very sexually overt product that is intended for established sexual partners - but it it is also usable in clubs, parties and raunchy/uninhibited situations but liable to backfire in the likes of work/polite company. You would generally moderate it a bit with the likes of IO or IS.
Instant Shine - IS is one of the most all round good products that AD sells - a happy/feelgood social product that is great on its own and combines very well with Ammo for one of the best attraction mixes.
IO - Again a light/bubbly social that helps promote conversation - makes approaching easier and helps you be more approachable.
Also the status products IG and A314 - IG is light, smooth, suave and sociable - which makes for a good impression, esp around younger women. A314 is the other end of the scale - Very high status, trustworthy and capable. Brilliant for work/professional use and very good to convey solid masculine presence in social/sexual situations - but maybe a bit too serious/LTR-minded around younger ones. Late 20s/30s is where a woman generally begins to tune into its signature big-time but you do get the odd exception.
Lastly, if you want a go of everything, there is the “Killer Newbie Kit” that gives a togo of everything for a healthy discount, so you can try the lot. The GC also counts towards this and it is a good way to try everything to see what suits you best:
Have fun!
