short
Okay, één van mijn vrienden heeft mij gevraagd hier even naar te kijken en mijn mening te geven. Sustanon Sostanon (E) en Sustenon (P) zijn een wereldwijde hit voor HRT, hoewel het hagelnieuwe Nebido de Sust op den duur wel zal gaan vervangen niet als origineel want die is gruwelijk duur, maar ik heb al samples gemaakt. En dat komt toch echt door de constante plasmaspiegel die meerdere esters bewerkstelligen. Op dit forum heb ik ook al eens over DuoDeca geschreven die wetenschappelijk onderzocht de synergie aantoonde van meerdere esters, op dit forum sprak men over DuoDrab
Mocht het je intereseren kijk het dan maar eens na.
Korte esters:
Ik geloof heilig dat Deca als lange ester veel beter werkt, en dat trenbolone-ester verhaal gaan we gewoon zelf ondervinden door het te proberen. Is dat akkoord?
Ik hou ook niet van korte esters en of ze nou van XX of XX zijn ****ed me geen klote maar waarom weer op de man spelen.....schiet niet op.
Short Esters Are Better Esters
Perhaps the most important thing I learned in reviewing this study is that short-chain esters (steroids of shorter half life) yield a much higher plasma concentration of steroid than steroids of longer side chain esters. In this study, a single 100 mg/ml x 1 ml intragluteal injection of nandrolone phenylpropionate caused a peak plasma concentration of almost double that of the 100 mg/ml x 1 ml intragluteal injection of nandrolone decanoate. This level remained increased for almost seven days, too. By fourteen days, even though the nandrolone decanoate ester demonstrated a much higher plasma level than the nandrolone phenylpropionate level, the net amount of both was so low as to be ineffective.
This tells me that the effects I can see from using 500 mg of Testosterone enanthate per week probably won’t be the same as using 500 mg of Testosterone propionate or even Testosterone suspension per week. I’m going to see better results with the propionate and even better results with the suspension. Sure, I may need to inject the propionate and suspension more often, but in the long run it’ll pay off.

Pharmacokinetics and Pharmacodynamics of Nandrolone Esters in Oil Vehicle: Effects of Ester, Injection Site and Injection Volume
We studied healthy men who underwent blood sampling for plasma nandrolone, testosterone and inhibin measurements before and for 32 days after a single i.m. injection of 100 mg of nandrolone ester in arachis oil. Twenty-three men were randomized into groups receiving nandrolone phenylpropionate (group 1, n = 7) or nandrolone decanoate (group 2, n = 6) injected into the gluteal muscle in 4 ml of arachis oil vehicle or nandrolone decanoate in 1 ml of arachis oil vehicle injected into either the gluteal (group 3, n = 5) or deltoid (group 4, n = 5) muscles. Plasma nandrolone, testosterone and inhibin concentrations were analyzed by a mixed-effects indirect response model. Plasma nandrolone concentrations were influenced (P < .001) by different esters and injection sites, with higher and earlier peaks with the phenylpropionate ester, compared with the decanoate ester. After nandrolone decanoate injection, the highest bioavailability and peak nandrolone levels were observed with the 1-ml gluteal injection. Plasma testosterone concentrations were also influenced (P < .001) by the ester and injection site, with the most rapid, but briefest, suppression being due to the phenylpropionate ester, whereas the most sustained suppression was achieved with the 1-ml gluteal injection. Plasma inhibin concentrations were also significantly influenced by injection volume and site, with the lowest nadir occurring after the nandrolone decanoate 1-ml gluteal injection. Thus, the bioavailability and physiological effects of a nandrolone ester in an oil vehicle are greatest when the ester is injected in a small (1 ml vs. 4 ml) volume and into the gluteal vs. deltoid muscle. We conclude that the side-chain ester and the injection site and volume influence the pharmacokinetics and pharmacodynamics of nandrolone esters in an oil vehicle in men.
