What to look for in concentrate!

So I recently got a med card and I am no longer restrained to the sales menu ( hallelujah ) because of the high prices and taxes in the state I live in.

I find even if I get higher thc concentrate it doesn’t always do the job like I assumed it would.

So what am asking is when I look at the different strains at the dispensary what should I look for so I know it’s a quality strain thats worth the price?

Bottom line is im sick of taking 2 dabs of a concentrate when I should/always only need one.

I just hate biting the bullet and buying a higher priced item to find out it was only higher prices because someone like mike tyson or something promotes or owns them and I didn’t know what to look for in a strain.

Bonus points for brand/strain recommendations!
