When you use any kind of steroid or testosterone over the course of three weeks or longer, your body stops making natural testosterone. Because of this, you need to make sure to implement PCT in order to help your body start producing natural testosterone again. You will need to start your therapy 10 days after your last dose of Sustanon 250, and all you need is a SERM, or Selective Estrogen Receptor Modulator. Nolvadex is generally regarded as one of the best, and you will use 40mg per day for the first two weeks, 20mg per day for the next two weeks, and then 10mg a day for one more week. You can continue it for a sixth week if necessary.
Do clomid if you want to make sure to get a good restart and if you are strong mentally, cons of this is that the side effects are harsher, is it worth the risk? Up to you really. Nolva if you are unsure, I mean most people will do just fine on nolva, so why even risk it, but if you are strong mentally, then you are not really risking anything, are you? Can you see how I am showcasing it as an dilemma because it will be different for each individual. With HCG it's easy, if you have the money then use it. The only down side is that it costs something, it makes the restart easier, and keeps testicle atrophy from occuring, it should be in every cycle, and if you don't have enough money to buy it, then reconsider doing a cycle, but it's not a total necessity, especially not for small cycles considering it takes 4 weeks for test to kick in.
For the dieting or cutting Trenbolone cycle this is where things can get really exciting as the choices are truly endless. In most cases you will be best served by supplementing with your Tren the latter half of the dieting phase; for example, if you are going to diet for 16 weeks you will want to use the Tren the last 8-12 weeks rather than from the start. You can also use the same overlapping method here as well; many athletes enjoy a Trenbolone cycle that overlaps with Equipoise during this period of use. As for other items, Winstrol, as always testosterone, good AIs and fat burners and if you can swing it a good batch of HGH and youll have a cycle that's hard to beat.
