I disagree completely with this. Your only 3 weeks in and you could stop and do a pct it would be much safer to do that then carry on with this cycle.
You say you have done your research but you wouldn't cycle at this age if you had. Your not going into competition are you? If not then its not worth the risk to your body.
Your friends and supporters aren't gonna help when you can't get it up for your GF or are they gonna step in for you lol
See sense man STOP your cycle. Your natural test levels will be at their peaks right now. Learn how to eat and train then in 4-5 years time do a cycle. It's really not worth it.
