Study: testosterone works better than Deca

Is testosterone works better than Deca?

In the late eighties the American army did experiments with anabolic steroids on soldiers. One of the experiments that the army doctors carried out was a comparative study on the effect of Deca and testosterone. Which works best? This is what the doctors wanted to know.

Nandrolone
Nandrolone [see structure in the diagram below] is almost identical to testosterone [structure shown below]. The difference between the two molecules is that the C19 methyl group is present in testosterone and is absent in nandrolone. As a result, nandrolone does not convert easily into estradiol and it has fewer feminizing side effects. The absence of the C19 methyl group also means that nandrolone interacts more strongly with the androgen receptor. In animal studies the anabolic effect of nandrolone is higher than that of testosterone.

Study
The doctors used thirty healthy and 'physically active soldiers' for their study. One of them was a cyclist, nine did weight training and twenty were runners. The doctors divided the soldiers into four groups.

Those in group 1 were given a weekly injection containing 100 mg of testosterone enanthate for a period of six weeks. The preparation used was Delatestryl, made by Squibb. Those in group 2 were given an injection each week containing 300 mg of the same substance.

Those in group 3 were given an injection each week containing 100 mg of nandrolone decanoate. The preparation used was Organon's Deca-Durabolin. Those in group 4 were given 300 mg of Deca each week.

Results
The effects of the testosterone injections are shown below. The second table below shows the effect of the course of Deca injections.

Of the light dosage injections (100 mg per week, by today's standards regarded as a homeopathic quantity by the average chemical athlete), Deca works better. One hundred milligrams of Deca builds more bulk than one hundred milligrams of testosterone, and breaks down more fatty tissue as well. And the increase in body strength also seems to be bigger.

The three-hundred-milligram per week doses worked better than the hundred-milligram doses. If you compare the results of the two heavier dosages, then testosterone comes out best. The weight increase is approximately the same for both substances – over three kilograms – but the testosterone users lose fat and the Deca users do not. What's more, the effect of testosterone on body strength is greater.

Some of the blood analysis results are shown below. If you want to base your verdict on the side effects of the two steroids on these blood counts, then the only thing you can really say is that there's not much to choose between them.

B = values at the beginning, D = measurements after six weeks.

The men in the testosterone group had higher concentrations of testosterone and estradiol. It's pretty clear why that is. The chance of the testosterone users developing gyno is therefore somewhat higher. But on the other hand, we now know that nandrolone is not only an androgen, but also an oestrogen.[J Steroid Biochem Mol Biol. 2004 Jul;91(3):99-109.] Because it has no C19 methyl group, nandrolone also fits in the estradiol receptor.

What is clear is that, certainly at the lower dosage, Deca has fewer negative effects on the testes. There is less volume decrease and sperm cell production stays nearer to the normal level. The difference between Deca and testosterone is smaller at the 300 mg per week dose.

Conclusion

Based on this study, you can conclude that at non-homeopathic dosages you can expect more effect from testosterone than from Deca. You could also conclude that Deca is perhaps safer. But recent studies cast doubt on this assertion. In animal studies high doses of nandrolone proved slightly more dangerous for the blood vessels than high doses of testosterone.

Anabolic steroids are made for use in small quantities. If you go for higher dosages, many of the positive characteristics no longer apply. In that case old-fashioned testosterone turns out to be more effective - and maybe also less risky.

This concludes testosterone is not just the base of all anabolics but at same time one of the more effective steroids ( except of course trenbolone ). Testosterone is life !!! Energy , mood , sex drive. If you have only test + tren you dont need more to get huge results yes , but in my opinion we should rotate all anabolics every some weeks to keep improving lihe we do with training and diet .

Very interesting. I wonder what causes the Testosterone to be less effective than Deca at lower doses but MORE effective than Deca at high doses....
