Every thing you say is "relative". Yes dbol is stronger than winny. But is it BETTER at producing solid gains i.e. fat free muscle mass? No it's not. You get a lot of androgenic sides. Because although it is more anabolic it is also more androgenic.
No I don't think "gains" are fastest at the beginning of a cycle. Effects are not the same as gains unless you mean oily skin, acne, increased sex drive. In my experience and THOUSANDS who cycle for years on end it takes more than a few weeks to build quality muscle. And because most steroids have a half life it is right around the 3-4 week mark that sometihng like Test E really starts to kick in. Yes deca may increase protein synthesis in the first week or two but "greatly" is a very ambiguous term and it's completely subjective. It takes several weeks i.e. 4-5 weeks for many to really start seeingthe muscle building effects of deca.
What you're saying is similar to you will build muscle the first time you workout. Well duh...........of course you will. But it will be at the microscopic barely noticeable level. After months and months of working out do you really start to see your physique change and muscle being added to your frame.
Longer cycles are better than shorter ones of course. But the laying down of new protein material is greatest when you introduce a new drug. It only makes sense. Since you mention training, yes it's exactly the same. After one workout you don't notice much but the response is the greatest when you introduce a new stimuli.
x2 I've researched Deca is best used at 12-15 weeks...
NPP on the other hand, gains can be seen after 1 week. Needs to be shot EOD, but make sure you have some caber/prami on hand to combat prolactin sides
Forums are great but they can also be dangerous. There are "truths" that are spread that are nothing but advertisements for new drugs you "need". I'm sure dopaminergics can be effective against some negative effects of Deca for example, but don't forget that these drugs can be a thousand times more dangerous than any steroid as well. Is it needed or is it needed to make money for the guy saying you need this and also happens to sell it? Did Arnold need "prami/caber"?
That nandrolone decanoate takes 4-5 weeks to start working but with NPP "gains can be seen within a week" is ridiculous. Same with TE vs Test Prop. Sure, longer esters may need higher starting dose to achieve same plasma levels since the drug is released completely over a longer period of time but these longer acting drugs start working immediately, just like test prop or NPP. Actually, TE raises plasma test faster than test prop (Emeric Delszeg actually taught me this as I didn't believe it but I checked the data and he was right). I also checked Schering's data on TE half-life (Testoviron literature) and they say something like just 2.3-4.5 days.
