That could be nearly anything in realty. The diet will control the "lean" part of it and I actually can develop strength on nearly any cycle.
So its this for me and you have to understand my body is a high metabolism and I cut veeeeeery easy bulk is tougher...I can run even deca with test and it still be lean gains. I can even lean gain on dbol (which I don't use anymore) even if I retain a little water in the dbol kick the water won't stay. Point is I drive that by diet. If you truly do want to stay lean but actually gain some muscle you could eat really big in the cals per meat and veggies but keep fat and salt out . We are all different as to what carbs we need to gain so that would require solme personal discussion. Compounds are not caps and there's no one size fits all, you are a unique individual. For myself I can carb load all day clean in meals and cut carbs by meal 5 no carbs meal 6 or the rest of the evening and its all lean and that even rolling deca! On the other hand I've worked with people who had to end carbs by noon on deca or it ain't so pretty! People will often say deca is goling to blow me up and moon face etc etc. Well, it can do me that way as well but if I roll prope AI and salt is literally "gone" from my diet and I'm eating proper "for the goal" then I don't have that at all.

So its this, you have to learn the compounds and your own carb need with individual compounds and cals to goal and over time you play with that and find all your "personal" reactions. Yes, we have compounds that have been said to be for cutting some for lean gains some for bulk etc etc but truth is you can "dirty bulk" on anything or clean bulk on anything or cut on near anything etc , it all comes back to "diet to goal".
If you are someone that has a hard time gaining for example, you will find it much easier to get even your smaller lean slow gains via an agent many would consider a heavy bulker but again, the diet does the work not the compound. So I think we talk about you as a person and your own metabolism and your plan for eating clean and your carb plan then we talk compounds once we have the real info that matters. Cookie cutter thoughts work for some people but many of us don't fall into the perfect little category and we happen to be the ones that learn how much more important food is over compounds.

If you ask me "what is the most important part of any cycle when it comes to the goal of that cycle?"
My answer for "most" would be carbs. Carbs control everything in the goal department and it takes time to learn them and how to use them for your own goals. This of course is assuming the diet is clean to start with. Btw, all gains should be strived to be "lean" at least to large degree. To dirty bulk is simply putting on fat with what little muscle you get and in the end it was a lot of waste and as well, not too healthy if this will be your lifestyle from now on as has been mine.
Personal reactions to food and your body type is where this convo begins with me though, not just throwing compunds at you thinking they will do the work ....the work is in the kitchen and that where the goal will be achieved or not.

I like a nice long 16-20 week cycle of test e and EQ. If you would rather use short eaters I think you'd like a test p and NPP cycle.

There are many combinations you could use but most people will recommend short esters for your specific goals. You could run test e and EQ, or test e And tren e. currently I am running test p, npp and winny and have similar goals. Good luck.
