still not finished yet but I made a start here.. http://juicedmuscle.com/jmblog/conte...steroid-esters

The website has been hacked. When the IT team brought it back online the pics where gone. Yesterday i tried to post new pics but didn't succeed, You can find the pics in the links posted here in this thread from all studies. Later i'll ,make an article about it on the blog.

If you watch the disappearence rate of sesame you can think how it will influence quickly diappearing short estrifications like by example propionate.

For some unknown reason I can´t klick on the icons, can you give me the direct links?

Thanks.

lets just all get together and celebrate the fact that we still have access to legit steriods at an affordable price......with that said i'm retiring to my room for a quick injection

Hopefully with more reputable studies + forums such as JM we can educate more people and start a grassroots campaign to repeal the "Anabolic Steroids Control Act of 1990" + the amendment - "Anabolic Steroid Control Act of 2004". Effective January 20, 2005.

One can only hope

We all learn every day, there are many studies done now, mostly thanks to us, we didn't believe the initial scaremongering from the whitecoats and used for athletic - performance - cosmetic reasons for anti-aging etc, now the scientist have reasons and funds to perform studies and surveys. Those find their way to the world wide web and we all benefit. Now with an aging population that wants to stay and look young and wants to maintain their libido etc scientists have more reasons ( MENT by example and HRT) just like pharmaceutical companies (see the moneymaker Viagra for pfizer) and what do you think happens if they would find a "cure" for obesitas??

thanks for the info, very informative. I never would have thought glute injections were better than site (delt) injections. See you learn something new everyday!

These studies are very useful and contain outstanding information. However sometimes I wish they would just dumb them down a little so that the average person can understand what they are saying without having to read it several times. Example if 100mg of steriod A is more effective when administered in oil instead of water...then I wish thats how they would say it......just sayin

I thought I was the only one [ that had to read it over and over ]

What about the older guys

Ronny thank you - I appreciate it very much. I am not quite there yet - but closer than I want to be.

And like Limo - I to have to read it several times. But it is very interesting - and very much appreciated.

What about the older guys

As I found out in posting about the subject, we have many older members, just like me.

Thus to balance after ...in healthy young men .. ..now what happens with healthy older men???

Older Men are as Responsive as Young Men to the Anabolic Effects of Graded Doses of Testosterone on the Skeletal Muscle.

Although testosterone levels and muscle mass decline with age, many older men have serum testosterone level in the normal range, leading to speculation whether older men are less sensitive to testosterone. We determined the responsiveness of androgen-dependent outcomes to graded testosterone doses in older men, and compared it to that of young men. The participants in this randomized, double-blind, trial were 60 ambulatory, healthy, older men, 60-75 yr of age, who had normal serum testosterone levels. Their responses to graded doses of testosterone were compared with previous data in 61, 19-35 yr old men. The participants received a long-acting GnRH agonist to suppress endogenous testosterone production and 25, 50, 125, 300, or 600 mg testosterone enanthate weekly for 20 weeks. Fat free (FFM) and fat mass, muscle strength, sexual function, mood, visuospatial cognition, hormone levels, and safety measures were evaluated before, during and after treatment. Of 60 older men who were randomized, 52 completed the study. After adjusting for testosterone dose, changes in serum total testosterone (change -6.8, -1.9, +16.1, +49.5, and +101.9 nmol/L, at 25, 50, 125, 300 at 600 mg*wk(-1), respectively) and hemoglobin (change -3.6, +9.9, +20.9, +12.6, +29.4 g/L at 25, 50, 125, 300, and 600 mg*wk(-1), respectively) levels were dose-related in older men and significantly greater in older men than young men (each P < 0.0001). The changes in FFM (-0.3, +1.7, +4.2, +5.6, +7.3 kg, respectively in five ascending dose groups) and muscle strength in older men were correlated with testosterone dose and concentrations, and were not significantly different in young and older men. Changes in fat mass correlated inversely with testosterone dose (r0.54, P < 0.001) and were significantly different in young and older men (P < 0.0001); young men receiving 25 and 50 mg doses gained more fat mass than older men (P < 0.0001). Sexual function, mood, and visuospatial cognition did not change significantly in either group. Frequency of hematocrit >54%, leg edema, and prostate events was numerically higher in older men than in young men. Conclusion. Older men are as responsive as young men to testosterone's anabolic effects; however, older men have lower testosterone clearance rates, higher increments in hemoglobin, and a higher frequency of adverse effects. Although substantial gains in muscle mass and strength can be realized in older men with supraphysiological testosterone doses, these high doses are associated with high frequency of adverse effects. The best trade-off was achieved with a testosterone dose (125 mg) that was associated with high normal testosterone levels, low frequency of adverse events and significant gains in fat-free mass and muscle strength.

promised

I promised that I would post some release rates once in my week-end house.
I made them when working for BodyPage thus they are in the Dutch language.

translation:
Dit zijn de milligrammen testosteron zoals die aan het bloedplasma worden afgestaan in de eerste 24 uur an een eenmalige injectie van Sustanon 250
These are the milligrams of testosterone as released to the blood plasma in the first 24 hours after a single injection of Sustanon 250
halve waardetijd = half life
dag = day
meting 1 = messuring 1

Yes , you should store AAS cool in out of light to prevent it from loosing strenghth, low temperature also prevents decomposition etc _ waterbased steoids are even more prone to this. Synthetic oils are better and more constistant, Eo by example only has one fatty acid (C18.1 oleic acid). A lower viscosity gives a greater injectiondepot and allows a quicker disapearence. As discussed here the injectionspot and the doses are important too.

For this reason Geneza uses an (expensive) synthetic oil for its injectables..

In this study: http://ajpendo.physiology.org/content/281/6/E1172.full you'll see that a higher dose of testosterone yields better results on muscle mass and the side-effects are (very) low.


...reading back the text I just assumed you all where healty young men ;-)

Great posts Ronny.
