If you're younger and are dead set on shutting down your natural test production, I wonder if it would be better for you guys to just cut down on the time off between cycles instead of blast and cruising? For long term health that is
I'll leave that one up the smarties like Det lol
unless you fully recover, i don't think thats the answer.
The problem i see is there is no reason to stay on such a high dose year round. Blasting and cruising is one thing, but he asked about staying on 500mg/w for the whole year. Like Det said, a host of other issues occur when this is done.
I have been on HRT for 3 years at 100mg/w of test and it has effected my HDL/LDL. Its not out of control, but it is out of norm (35/126 respectively). These are things that happen regardless and that is with a baby amount of test.
Now, with all thet being said, i loved long cycles, but i always came off for at least 6-8 weeks. May not have been optimal, and yes I am on HRT for life now, but if you're gonna do long cycles, i like the switching compounds idea to continue seeing gains. Here's a fav i did one year.
Week 1-24 Test Enan 750mg/w
Week 1-12 Deca 500mg/w
Week 13-24 Tren E 400mg/w
Yes, that's alot of 19nors, but i made great gains that year and stayed off for 4 months after that cycle and recovered fine. I will say that was when my levels started coming back lower than my baseline, so i figured the T was on the steady decline. I wanted to compete so the next year i had one more run and competed in 2007 and BAM, now I'm on HRT.
So its not an exact science, but since you primarily asked about gains, and not about whether it was a good idea or not, i wanted to give you another answer besides that.
