First thing you should ask yourself is what you’re looking to get out of your cycle. Some compounds work really well for somethings and not so well or at all at others.
Basically the compounds BUDs ran, Tren/Test/Mast/Var, work very well for strength gains, quality muscle, staying or getting leaner (although not ‘cutting’ drugs they do exhibit a leaning effect) and little to no estrogenic effects. Tren is a very good compound however it can be very damaging as well if over used and abused. So it’s not recommended for long cycle usage. Also, as he stated, should be stopped a couple of weeks before the test.
You ask why those and gave some reasons… well you have to look at the compounds in combination. Certain compounds compliment each other very well and in so you get a great benefit from ‘weaker’ ones like Var. Although if you run the right dosage you’ll be fine with it.
I’ll add to the above discussion about your PCT… I’d suggest running HCG during cycle so that when you hit PCT time your recovery is much easier and faster. No downs at all. Or shouldn’t be if run properly. As with anything else there’s a correct way to run HCG during cycle also. I would NOT suggest running it throughout the whole cycle. Perhaps just the last 8 weeks of a 12 week run.
Lots of info to digest. Just keep doing research and when you;re done… do a little more.
