Testosterone Acetate has a faster rate of absorption in the body then other esters. Levels peak at 12 hours so it would require you to inject daily to keep your testosterone levels consistent. Miligram per Miligram you will have more available testosterone with Acetate then you will have with any longer ester based testosterones. 100mg of Testosterone Acetate will feel stronger than 100mg of Testosterone Propionate.
As a general rule, the faster/shorter the ester, the higher the predisposition for PIP (injection pain) when it comes to Testosterone (Test). Injecting a long estered testosterone like Enanthate twice a week will give completely stable blood levels of test.....so why fool around with short esters? Here is why:
If you are on a gram and a half of test like a competitive bodybuilder, you are going to always have very high blood levels of testosterone. But of course, that is not very healthy. For those more health conscious, much lower levels are selected. A relatively safe cycle will have 400-500 mgs of test a week. An HRT dose of testosterone is under 250 mgs week. Keep in mind, you are on HRT nearly year round, and that is why you shoul stay at or below 250. Testosterone acetate gives you a short term boost when you need it.
Lets say you have a particularly tough workout that day, followed up by a hot date. Shoot some testosterone acetate 4 hours before the workout. 12 hours later your levels peak, which is great. You will be a beast in the bed, and by Sunday night the acetate will be mostly gone, so you stay healthy.
Another situation is one I encounter frequently: The bodybuilder who is on very high dosages all the time. There are those foolish enough to run 2 grams of gear a week for years at a time. They are walking time bombs. The best I am able to do with these guys is to get them down to a test only cycle. Initially, one gram of test a week is as low as some go. Crazy, but that is competitive bodybuilding.
Eventually, I try and get them lower, 400 mgs/week is the goal. At that amount, they claim they are having difficulty training and feel lethargic. That is where testosterone acetate comes in. They are down to 400 mgs/week of Test enanthate, and if they are dragging I have them use a shot of Testosterone acetate 5 hours before coming into the gym. They also can use the testosterone acetate if they have a date and need to perform sexually. Testosterone acetate can save the day, or night.
Testosterone acetate is also great for ester clearance. You need 20 days to fully clear a long ester like Enanthate. Testosterone acetate and propionate work well for this purpose. Testosterone No Ester (TNE) is also popular for this purpose, and it hardens you up for a competition.
Testosterone acetate, propionate, and TNE are great for the last few weeks of contest preparation. You cannot risk the water retention from Testosterone Enanthate, so you replace it with a short ester 3 weeks out.
However, there is one catch: The shorter esters and no ester forms of testosterone are notorious for pain (PIP). TNE, an awesome pre-workout, is the worst. Propionate is not as bad, but still painful. Propionate is a somewhat longer ester than Acetate and can be injected every other day.
Testosterone Acetate presents a challenge to those who make it. In general, the shorter the ester the more likely that there will be PIP. Our Acetate is well tolerated/painless. Another benefit is the clearance rate of this Ester is favorable for tested athletes. An important note to take is that Testosterone Acetate will also aromatize a lot faster than the other Esters so you will have to take precautions if you are trying to manage estrogen based side effects. 100mg of Acetate is a lot stronger then Enanthate so incorporate a SERM or anti-aromatase in conjunction with Testosterone Acetate.
