Why is it important to run an AI when on cycle?

[Swifto]

I thought I had read in a pct post that aromasin is a suicide inhibitor to estrogen (thus killing all of it in your system) while arimidex will just inhibit the estrogen from binding to receptors (decreasing estrogen effects by 80%, this is just from memory so might be wrong). Above you stated we wanted some estrogen but not above 50ng/ml. Long story short, why doesn't aromasin completely deplete estrogen levels?

Its a suicide inhibitor, so it attaches to the aromotase enzyme and kils it, stopping it from becoming active again.

The dose of the AI is important. 10mg/ED is inhibitive enough for most people to use "on cycle" and keep estrogen in normal ranges. Some will need more, some less.

I never said Aromasin will destroy "80% of estrogen", Anthony Roberts (Conners) said that looking at its effects in females (not males) whilst not taking age into account as well. AI's do not effect males as they do females when looking at estrogen suppression.

The study I posted above looking at IGF-1 levels (showing no impact) when using Aromasin also looks at estrogen levels, have a read of it.

Hi Swifto,

I am age 54, on my second cycle. 1st cycle plan was 12 weeks of sustanon 500mls weekly with 20-50 mg dbol daily starting with 30 and adjusting as needed. I chose sustanon because when i last cycled at age 24, it wasnt available and I got mesmerized about 4 different esters in one. Bottom line is I didnt start seeing gains until week 10 so by week 12 I knew I had to extend the cycle a couple more weeks and alos drop the dbol as it gave me bloat which DID disappear upon dbol cessation. Didnt seem to do anything for me anyway. I used no AI or PCT and was 8 weeks off cycle and all was well. My regular doctor took my blood work and said my test and estro were fine along with eveerything else including BP and cholesterol and sugars. Just my thyroid was low(#8), but its been that way for 12 years. I live with it.No I dont have a copy of the blood work and by the way my doc doesnt know Im on AS. He will only do bloodwork every 6 months unless something is very wrong. Lousy Obama care insurance.

Now I start my 2nd cycle 2 weeks ago with just NLP and test prop, for 1st week of 500ml's total, 2nd week I add in baby dose of enanthate still keeping mls under 700 per week, and the plan was to just use the prop and NLP for 2-3 weeks to jumpstart things and cruise on 500 mls test enanthate spit twice per week for a total of an 18 week cycle.

Im now experiencing slight testicular atrophy after week 2. Is it the no ester NLP? Because I never used that before , and I also never had any sides other than oily skin and huge libido increase before even in my 20's. I also have always had difficulty in reducing bodyfat as when I gain size my BF often stays the same and the gain is all muscle but I get awful insomnia if going under 100 carbs per day, plus I get constipated so I need lots of fiber which has to be carbs. I would like to know what would be a good AI that also would help me get "cut up" (thats how we said it back in the 80's. lol) I have armidex,aromasin,clomid,and nolva on hand. And what about proviron which I have 9 pills? Due to chronic fatigue and the thyroid issues ive had for yrs even when clean, I cannot get blood W. for a few weeks at least due to time issues and as I said, they wont do it at my clinic more than every 6 months. So lets wing it for now. Being I kept most of the weight from my last cycle going from 170-185 at 5'9 with like 23% bf, all Id like to do is gain maybe another 10 pounds and then focus on getting ripped. Its weird but I actually look thin with a long sleeve shirt on but in a bathing suit my stomach is flat but you cant see my abs unless I flex. The illusion of size will be awesome once I can add just 10 pds on my 5'9 frame and cut it up! I read on another forum that HCG will give me the test back in my balls to stop the atrophy but I know nothing about that and my source doesnt sell it.DO I HAVE TO USE HCG FOR THE ATROPHY? Also I currently 10 days ago added in b12(1000mcg) pins every other day for my chronic fatigue but it gave me insomnia and weird anxiety like drinking 2 pots of coffee so i will cut the does in half and do it once per week.My insomnia is so bad I cant sleep without a sleeping pill just naturally! Plus Im on tramadol for pain killer for 3 ruptured back discs that have been with me for yrs. Also makes me tired.Thats why I cant tell my doc Im on AS. hE WANTS ME OFF PAINKILLERS AND SLEEP AIDS TOTALLY IN 30 DAYS, and it aint gonna happen. Been there tried it(8 times) Suggestions on all this please?

I just read this post and its awesome. Would like to share that I use .25 exestane every other day. I do 200 mg test cup a week. And 250 Iu hcg 3 x a week. It keeps my estrogen perfect and my igf-3 is still high.
