Mate you need to really do your research before jumping in for the first time. Epi is a good compound to start off with, but it doesn't come without sides. I'm just finishing a five week epi/ halo cycle today and I've had a great run gaining a good few pounds of lean mass while leaning out. Tomorrow I start my pct. As whiskey said above one of the things you'll probably experience is lethargy, which could be a real bitch. You really need to run some sort of test base along with epi to combat this. I ran OL Sup3r dhea which is a topical compound and it worked well for me, although I would have rather used Dermacrine but none was available at the time so I went with the sup3r dhea. Another issue is back pumps. Although I never really had much of an issue, I still got some taurine to keep on hand in case anything occurred, also a couple of bananas before your workout should help. Epi lowers estrogen as well and you could experience estrogen rebound after you stop using it. It's a good idea to taper off cycle. I ran my Epi at 20/30/40/40/40 and the last 4 days, tapered down 40/30/20/10 stopping your cycle immediately on a high dosage could cause rebound issues. Get a proper serm, nolva or cloned. Tomorrow I start my nolva for 4 weeks 20/20/10/10 along with a natty test booster. Also get a proper pharma AI to keep on hand in case you experience any rebound issues after pct. Do your research bro. Plan out your cycle. Plan a proper pct and you'll have a great run. Oh and drink as much water as you can. Hope this helps
