Doubts about the programs

Hi there,
I’ve downloaded the app on Android and been running the small load preparation intermediate program.
I’ve been also trying to read all the threads so I don’t ask something somebody has already asked but I’m still hesitant about a few things.
1-   When I set my PRs, should I set the weight that I want to lift once I’ve peaked or my current PR?
2-   I started with the small load preparation intermediate program just because I thought it would be right to get used to the intensity that Sheiko’s programs demand. But I dunno really how to move on. I don’t know whether I’m an advanced or intermediate lifter nor how to pick the amount of load.
3-   Should I do the competition programs even though I'm not yet competing?
4-   Is it necessary to perform any deload phase like in western programs. Or once I’m done with one program I carry on with another?
5-   For the sake of aesthetics, I like working out my biceps. When would you suggest training them? Shall I create an additional day?
6- When it says chest muscles, it's only thought  the chest to be worked out? or I can work out my shoulders/triceps instead (which would also improve my bench) ?
Well that’s it for now, thanks in advance.
Kind regards

1. Is addressed somewhere else in the forum here, in short you can change them gradually, or add the extra to your 1rm in one go.

2. If you get good results it might be worth doing the same program again, if you get no results or regress and you are gaining bodyweight still you might want to try a harder program.

3. Yes, it peaks your training cycle, you should follow the whole program through each block.

4. You can go straight to another program, personally I tend to take a break and try something else for a mental rest, but in hindsight this is usually making me weaker.

5. Just do it at the end of each training session, if it interferes with the program, dial it back.

6. You can modify the program as you see fit, Boris encourages it as you are a co-author he says.

I think if it's your first run then do the program as is, see what works, switch out what doesn't.
