Great Decision not to start gear at age 18. Train had another 5 years before you try it.
I have used OT and did do Nolvadex for four weeks afterwards. Perhaps it was overkill, perhaps not. I did a proportionally longer cycle of OT than most advise. I did 2 months or 9 weeks at 40mg ED. 4-6 weeks is generally what is recommended with 6-8 being the absolute max.
In terms of testicular shutdown, it was mild after a few weeks but right around that 7th week it became even more apparent. I only had what I knew was a 2 week supply left so I made a choice to finish it off. The last week was were I finally started noticing some lathargy, some of the lower back pain pumps people refer to, etc.
All in all the gains were mostly lean. [I believe OT’s androgen score is actually 6 not zero] I was trying to eat a lot of protein and calories of course to maximum my gains which could be why I for one did not experience much in the way of fat loss that some claim can be had from OT. By the end of nine weeks I had a scale weight change of 11-12lbs. My strength increased appreciably as well. I did the nolvadex for 4 weeks at 40mg the first week, 30 the second, 20 the third and 10mg the final. I also downed a bottle of Liv52 during my month of PCT. One month I after I stopped the cycle i.e. at the end of my month of nolva my BW was only 1lb less than at the end of the cycle. My strength and body composition were the same; which is to say they neither went up or down. It should be noted I did catch a cold during my post-cycle period about 7-10 days after my last OT. This cold lasted a week during which time I didn’t train fior six or seven straight days. So all in all I would say I retained my gains quite well considering I was ill for a week. Although it could also be argued I was getting to the point of being overtraining while I was on OT; so the week off was probably a very good thing.[Whether that cold was caught because of an extra long OT cycle or not is debateable]
I have also used DBol many, many moons ago and do not have as detailed statistics on my results on it. However, I seem to recall feeling slightly more pumped up on DBol and looking slightly bigger while on it [no doubt the higher degree of water retention]. I do also recall that a few weeks after I stopped DBol the puffy-ness was gone but some of the size and strength had gone away with it as well.
By general concensus DBol is the superior product for size and strength. However, OT was/is not a bad product at all.
Again, thank yourself for making the wise choice not to gear up while you’re still in your teens
