Hi guys,
As you can probably tell, im new here. Ive been reading for about a week now, I have some questions about testosterone I hope you guys can help me out with. Take test cypionate for example. It is a slow acting ester, how long before it starts having an effect on your blood test levels? I have heard 4-7 days, is this correct? It stays active for 2-3 weeks, is that correct also?
I read that the average male produces around 200mg a week of test, correct?
It starts affecting your blood levels within days,but you wont notice any difference or results until about 4 weeks. Cyp half like is around 12 days, so depending on how much you take, depends on how long its active, but 3 weeks is a rough estimate. The average male produces between 40-70mg a week.Quote:

Also I understand you immediately have available testosterone from a cypionate injection but you just wont feel anything until blood levels are over about 6 times above normal which takes weeks to build up. On the other hand it takes 3 weeks for your natural production to shut down so while you are starting to get some availability from the injection, your nuts are still producing for a while.Quote:

not anything over... if you produce 40mg a week, then 40mg injected each week will shut you downQuote:

Well LH is slow to leave the blood stream. Your body doesnt expect to react quickly to drops or spikes in testosterone, which is also why we are slow to get it restarted again. We usually have to use things like clomid to accellerate this sloooow process of getting production back to normal or near normal. Your HTPA recognizes the new testosterone, in fact I understand it actually spikes production in the first week and increases natural production before shutting it down. The HTPA will discontinue LH releases at the second week and it takes the 3rd week for the LH to dissapate from your blood supply causing the nutz to shut down.Quote:

Estrogen causes more profound reaction to your shut down then high testosterone. 10% of your testosterone converts to estrogen and its most likely that blood estrogen levels are the primary control mechanism on the HTPA. Some of us as we get older dont stay on the 10% conversion to estrogen, in fact its closer to 15% and 20% for those guys having troubles with testosterone production.

I guess I see why so many people frontload.....
Thanks guys, I appreciate the info.
Ok, just so I understand...it has to match what your body produces(or more)? So if your body produces 40mg a week, 39mg injected will not shut production down? Then 40mg a week injected and over will shut you down, right?Quote:

You quickly reach a point where you are completely shut down. Don't worry about that for short (10 week or so) cycles. Part of your injected test simply replaces what you aren't producing, so there is a tremendous difference between 100mg/week (not even noticeable) and 200mg/week (some modest gains with hardly any side effects, in beginners.)Quote:

Because each of your last several injections have left some test in you that has not yet left the body or been converted to other compounds. You have to consider each shot individually, and you can roughly calculate how much of that shot is left in you. So after 4 weeks or so, your first shot still has a small amount left in your body. The second shot still has a tiny bit more remaining. The third shot, still more. Finally you get to the most recent shot, which is still 100% in your body. To complicate things, the hormone is released into the bloodstream slowly, over time, so your serum test levels are not much influenced by the shot you took yesterday. So you can see how test builds up in the blood over a long period of time, much longer than the half-life figure.
Some users will "jump start" a cycle of cyp or enanth with a short ester such as prop, or with suspension, for the first four weeks, so that levels are high and the hormone is making it's effect felt after only a week. (oral jumpstarting is more common though)
