EQ has a half life of 14 days. Most people stack EQ with either test e (half life of 10.5 days) or test cyp (half life of 7 days). Because of the long half lives, a lot of users will kick start their cycle with an oral like tbol. You do not need to add an oral kick start to your cycle though. It'll just take a bit longer for you to notice the effects of your cycle. A test + eq cycle is a great cycle. It's best to run the cycle for a long period because of the long half lives. I like 12-16 week test + eq cycles.
You are right that tbol is a liver toxic oral steroid. If you decide to add it into your cycle as an oral kick start, it's a really good idea to use a good liver aid supplement when running it to keep liver toxicity to a minimum. Look for a liver aid supplement based on milk thistle, TUDCA and NAC. I really like the product n2guard from n2bm.com.
