Just started sus 250g thinking of a cycle like this
1-10 sus 250 1ml a week
2-20 forma
4-8 beast 2-3tabs a/d
4-8 liver support
6-10 Hcgenerate
10-14 unleashed/post cycle
10-16 forged steel
16-20 bridge
bit of advise if cycle looks good or not
Start your pct 3 weeks after your last pin. Sust has 2 long esters that linger in your system. Some guys wait 2 weeks. You want the sust to be completely out of your system before starting. Also I'd run a liver support during the whole cycle not just while running beast. Yes bridge is a good product but no you don't have to run it. Are you taking anything else like fish oil, creatine, multi vitamins or anything?
*Edit
Also it might be a good idea to grab an AI like adex and have it just incase of gyno issues
No you need to protect your liver throughout the entire cycle. Even though you're using an injectable it still passes through your liver and kidneys. They are the filters of your body. Sustanon is toxic on the liver, as is all aas.
