Mmmh without an AI it depends a lot on how much your body handles estrogens.

A good rule can be Test = Mast then add EQ.

Let's say that... best offseason lean mass protocol for sure is: TEST DECA EQ (some dbol here and there) HGH Lantus Humalog.
But i don't like these cycles since it puts on my a lot of water and i prefer a modern approach: TEST MAST EQ

Test is always KING of mass builder no matter what! I used in the past really low Test and high anabolics.... BIG ERROR!!!
You have to learn how to use HIGH DOSES OF TEST no matter what.
To handle high doses of test we have MAST and AI, so let's say you are superestrogenator 1g TestE + 1g MastE + 1g EQ

Test dose depends much on how developed you are for a first timer on steroid with no much lean mass 500mg is plenty, for 2+ year user 750 is ok
for more than 1g you MUST add HGH no matter what or you will blow up like a baloon and will looklike shit.

If you decide to use high dose of HGH(6iu+) and TEST (1g+) for blow up be ready to add slin, and if you want to use slin you have to study a LOT how it works, it's not easy stuff to handle, and tbh if you want to use slin your aim is to became a MASS MONSTER like the mods here....

In my opinion, if you are a random gym rat like me just stay at max 700-900mg TestE + Masteron + Eq, to find your sweet spot of use multiple Enanthat+Propionate esters both for Masteron and Test.

If you use Test Mast Eq and have anxiety it's due to E2 not in check, spam Aromasin 25mg eod to destroy E2 add 5mg Taurine (helps a lot with anxiety and GABA) then add Adex. Usually i do that: 200mg Test -> 1mg Adex, 200mg Deca -> 0,25mg Adex, 200mg Eq -> 0,5mg Adex but that's me and i'm pretty estro prone.

With all MTS products i will do: 600mg TestE + 400mg MastE + 1000 Equimax and that will be your "base" on top of that play with TestP and MastP
once found your sweet spot you can add 4 weeks on/off of Dbol/Anadrol/Dbol+Anadrol (1:2 ratio).
When bulking i found that the less you stress your body the more you grow so keeping TrenA away it will be okey, but if you want a more conditioned and dry look add 350mg TrenA or 400 TrenE.

Test Tren Mast Eq are ALWAYS a good choice for an already pretty developed body.
Test Deca Dbol are a good choice from a rebound from a superlean state (ie. superlean gymrat or just out from a competition)

Basically supersimple cycle like CUT with low Test high Tren then BULK with Test Deca Dbol are best bang for buck.
