From the info given there's no way to know the amount of product in each pill. 4:1 can mean 100mgs MDMA/25mgs of MDA or 400mgs MDMA/100mgs MDA although it's more thag likely in the 100mg MDMA/25mg MDA range. I'm assuming since they're from the same presser that the contents will be similar but this isn't always the case. Have you ever had MDA? It's basically a longer lasting, more visual, more euphoric, less empathetic version of MDMA that many people, me included, prefer over MDMA.
Out of the pills you listed I personally would go with the thumbs up as those are an almost 50/50 mix, the MDMA/MDA combo is fantastic btw, you came accross some great pills. Maybe start with a thumbs up and redose later with a re-boot and save the alien for a more pure MDMA type experience? This is what I would do but I don't know if you like MDA, being that you also live in cali you've probably never had MDA before. I didn't until I moved to TX for a couple years and there were quite a few MDA tabs going around. If this is the case take advantage of this opportunity and see what the thumbs up have to offer, no it's not pure MDA but you should be able to tell the difference between those and your average MDMA only press. Have fun!
