I, too, only recently learned about sarms and that they can be taken to build muscle. I don't take Sarms yet, but I'm thinking of starting. I study very carefully all the information about sarms at https://paradigmpeptides.com/. Sarms has passed all validations and independent tests for purity and safety. Some Sarms products are over 98% pure and that says a lot. In order to study the composition in more detail, you need to select a specific product that interests you and in this way, you will find the composition.
I read a lot of positive reviews about Sarms products and it bribed me.

I've never heard of this app before. If it really helps with motivation, then you should probably buy a subscription. Isn't there a trial period for this application?

I recently downloaded the Oka Mirror app for Samsung TV. Naturally, before downloading this application, I read the reviews and only then decided to download it. Well, I would recommend you do just that, good luck. More information can be found here okaapps.com.
