I think everything in the first category, the test/trest/Tren & an oral eventually are perfect. This is exactly what I’m on right now, and I have put back on 20lbs in 20 days. 210 test e, 175 Trest Ace, 140 Tren Ace/wk split into daily shots.
This is a cycle Mike Arnold has used and advised for fast comebacks; he reported something like 35-40lbs regained in 6 weeks after a layoff (maybe during COVID if I recall right). He recommended Anadrol, but I know he’s a Superdrol fan. I can’t eat on orals so I am using 500mg primo/wk.
Context is important here. I had intentionally lost 20lbs over the previous 6 weeks coming off a comp, then decided I really want to pursue a bench goal immediately. There is no reason to need something this aggressive just for general size accrual; Smont already gave some great alternatives that would be much less damaging to the cardiovascular system.
As for the next part, pick HGH & Slin, or IGFLR3, or Mk677, depending on budget, availability, how many pins you will go through. I listed them in their ideal order. I am currently just using Mk677. Its dirt cheap, helps my appetite on this power bulk, and between Trest, Tren & GW my glucose levels are way lower than normal - I have the insulin sensitivity to use all of this food that would normally be problematic with MK.
Follistatin is junk. Yk11 is nothing special, and a lot of it is allegedly actually old cheap Epistane raws, especially the older stuff. Which, you could just run more Superdrol or the like.
Letro will be overkill unless your doses of test & Trest are, and you certainly don’t need it or Prami in PCT. I do not need any AI or SERM currently with the 500 primo in place, and am using P5P to manage prolactin acceptably so far.
Regarding PCT itself…if you need to PCT, don’t use 19-Nors. Trest is not a drug for people who intend to use their own balls again.
