32 yr old male considering first ever cycle: Advice would be super appreciated

First of all greetings to everyone. I am new to this forum and hope the experience offers an array of detailed and up front of advise that will be greatly appreciated.

I am a 32 yr old male who has been training for 3 years. I started at 59kgs and have slowly (with some hiccups along the way) worked my way to a current heavy of 73kgs. It appears to be the ceiling and I am considering the next move of a cycle to continue on. I would ideally like to add another 5kgs or even get to 80kgs if possible. My stats are:

Age: 32
Height: 175 cms
Weight: 73Kgs
Body Type: Ectomorph
Body Fat %: 8-10%

My current split is a 2on-1off day routine and my diet is as regular as balancing a full time employment allows.

I have done some research and I am currently in favour of Sustanon 250 and so I would like to kindly ask the community on:

what would the recommend dose /
the days(s) of the week I should inject /
What PCT should be considering and what should I get to prepare and how long should I be on it for
Any recommendations on ideal training splits or does it really matter?

Any other advise would be much appreciated.

Thanks,

500mg a week split into two jabs.
Monday 250mg
Thursday250mg
You also need to have an ai on hand like arimidex
Pct will be nolvadex and clomid

Welcome!

Also, look into HCG. It is easily purchased through a chemical research company. Read as much as you can! The above recommendation is correct...just not complete!
Test E,C or Sus injected 2xweekly to keep levels "stable"
An "AI (Aromatize Inhibitor)" like Arimidex, M,W,F @ .25mg (adjust according to blood work)
A "PCT (post cycle therapy)" of "Clomid" & "Nolvadex" READ ON PROPER TAPER!

Hope this helps!
