Any muscle lost over such a short period comes back in an instant, unless the issue you had won't ever be resolved after your convalescence. Twice I was on a ventilator for 3 weeks and lost 70lbs each time while intitially being so weak I couldn't drink a cup of water without a long straw, nor even stand up 5 seconds with a 200 heart rate

Each time I was back in 3 months size-wise although with some lingering issues limiting myself in lifting but the "image was back" within weeks, like blowing air into a balloon.

IMO all the steroids work the same but some are more quick acting. But if I wanted to do an instant-comeback, an Anadrol a day would do it added to the test, 3 weeks and you are back. You want to add Primo/EQ/Deca, that's fine but it's not instant muscle like with some orals. Some want to take their time, some are in more of a hurry .
A quick recomp that scaresly no one will try: eat protein as much as you can only apart from around the workout, then take 15 units of Novorapid or Humalog etc preworkout and follow up with 250 grams of carbs and some aminos the next 2.5 hours. 2-4iu gh a day. Test base, could be just 250mg, and one Anadrol. Clen 60mcg a day. Could look better than before your lay-off with minimal, imo, risk to your health

After 3 weeks resume your previous base use of roids or even less.
