I've been looking for a good guide and pretty much all of them are confusing as hell.
Potions are the easiest way to make MASSIVE money. Well, they would be if any darn merchant had more than a few coins.
You gain more XP by making potions that cost the most. Cheap potions yield next to nothing. I've been looking for a list of expensive potions and here is one I found.
Giant toe and wheat - Most expensive potion £2615
Giant toe and Blue mountain flow - same potion slightly less expensive
Bee + Fly Amanita + troll fat
Chourus Eggs + Vampire Dust - £1121
Garlic and slaughter fish - £1014
Frost Mirriam - Purple Mountain Flower - £1014
Ice Wraith Teeth = Vampire Dust -£1143
Briar Heart / Canis Root / Imp Stool - Any combo of 2 £954, Paralysis
Blue Butterfly wing & Springgon Sap - £947
Glow Dust + Spriggon Sap - £899
Glow Dust + hanging Moss - £1222
Salt & Deathbell ( or River Betty) - £828 Slow
Thistle Branch & Sloughterfish Scales - £600
Juniper Berries + Skeever Tail - £539
Tundra Cotton & Void Salts - £529
Blue Dartwing & Orange Dartwing - £506
Ectoplasm & Red Mountain Flower £454
Always check merchant apparel until you find something with Alchemy boost then disenchant it and make a set with the maximum enchant boost you can make. You can enchant head, neck, ring and arm slots with alchemy boost. Enchant on any of these items. They can be cheap items. The enchant is the same for an iron helm as it is on a daedric helm.
Get the bonus by visiting the Lovers Stone. This gives a 15% bonus to all skill XP.
BUY EVERY INGREDIENT EVERYWHERE. Every single time you enter a city for a quest, always stop off at the potion shop.
Keep lots of potions in your inventory to sell back to the store after buying the ingredient. Eventually, you will always get all of your money back and have 100s of leftover potions. Store some in your homes because they start to weigh you down, BUT ALWAYS keep enough to sell back to get your money back.
You can TRAIN your alchemy up to 75 but only 5 alchemy levels per character level at the potion store in whiterun. (MAKE SURE you have lots of potions to sell back to her to get your training money back. Especially later levels because she will have up to 9 to 10k gold.
It is a bit boring but just hop clockwise from city to city buying up all the ingredients from the stores until out of cash, then go make potions and do it all over again.
All of the above ingredients can be purchased at Whiterun and the Dark Brotherhood Alchemist. I haven't started the Dark Brotherhood yet but I've been hoping to all the other stores.
Make sure you use your perks on making the potions stronger. That increases the price thus making it level faster.
I found this guide today and in a very short time went from 70s to 90s making the EXPENSIVE potions.
More good potions here. LINK
Using those two lists you can level Alchemy very fast once you hit the stores.
