I have a question.
Your buddy at the gym that's "huge", how long has he been using AAS(steroids), and where did he get his information from?
The reason I ask is that there is a lot of bad/wrong/stupid information that gets passed off as valid and correct, which is what your buddy has passed along to you, another example of this is my brother-in-law. He has over 5 years of AAS experience under his belt, but has been off for the last 2 years. He has just started a Winstrol only cycle. When I asked him why he wouldn't use test with it, and why he was using Winstrol in the first place he responded with "because I don't want to get huge, I want to be ripped for summer".
This is incorrect information.
Winstrol does not make you lean and ripped, it dries out your body, giving it the appearance of being more ripped, however after you come off of it not only do you lose the "ripped" look, but your natural test production is so low that you feel like shit, can't get a boner, and lose the muscle that you have(without testosterone, you don't have much of a chance of keeping your muscle).
As for A-bombs, for most people they bring with them the most harsh side effects, i.e. a sickly feeling constantly, bloating, hair loss, completely shut down natural test production, which, as you now know, means that you're not going to be keeping the gains.
The reason that Anadrol and Dianabol are considered great "kick-starts" to cycles is because people are using Testosterone as their cycle base, for anywhere from 12-20 weeks, with the A-bombs and D-bols being used during weeks 1-4 or 1-5, with the reason that the orals will give a huge boost to your strength while the Test is getting into your system.
Giving yourself an injection is actually very simple and very safe, you can do it for sure.
To reiterate what's been said already, at 160lbs you definitely need to be militant with your diet. Saying that medications etc get in the way of your appetite is only an excuse. Put yourself on an eating schedule. Seriously. That way even if you're not really hungry, you'll know that you have to eat, and, if you don't eat it won't matter what kinds of steroids you take, or how you train, or what you do for post cycle therapy (pct), you won't be able to maintain any sort of size gain, because your body will not be getting what it needs to keep the size, plain and simple.
As for post cycle therapy (pct), hcG is not to be used with Nolva or Clomid, you use hcG during your cycle and before you start your post cycle therapy (pct), for post cycle therapy (pct) use either Nolva, Clomid, or you can use both.
