Should I buy concentrate mones to mix my own ratios? Or get prepackaged mones like scent of eros and alpha7? Where is a reliable place to buy?
Unless you’re an amateur chemist with a good amount of knowledge and experience with pheromones and what molecules do what, you’re far better off using premixed products.
I hear LS products are good but I have not used any. No need as I’ve been more than satisfied with AD products.

Yup - read the post above and stick to premix till you have begun to find your way. Then explore mixing with some useful knowledge.
You’ll waste a lot of money if you start this with random molecules and little knowledge. You’ll be one of those who who swear that mones are bull because you’ll have tried and seen that they have no effect.
