nolva/ liquidex???

[FRANk THe TANk]

i had wanted to use nolva/aromasin for pct, but i cant get a hold of any aromasin... is there much difference from liquidex? whats a good dosing schedual>?

[FRANk THe TANk]

nobody?

thanks for the swell advice

Here is the response to your question... this is a write up by Anthony Roberts...

"Difference Between Type-I and Type-II Aromatase Inhibitors

To understand why Aromasin may be useful in conjunction with Nolvadex while both Letro and A-dex suffer reduced effectiveness, we’ll need to first understand the differences between a Type-I and Type-II Aromatase Inhibitor. Type I inhibitors (like Aromasin) are actually steroidal compounds, while type II inhibitors (like Letro and A-dex) are non-steroidal drugs. Hence, androgenic side effects are very possible with Type-I AIs, and they should probably be avoided by women. Of course, there are some similarities between the two types of AIs…both type I & type II AIs mimic normal substrates (essentially androgens), allowing them to compete with the substrate for access to the binding site on the aromatase enzyme. After this binding, the next step is where things differ greatly for the two different types of AI’s. In the case of a type-I AI, the noncompetitive inhibitor will bind, and the enzyme initiates a sequence of hydroxylation; this hydroxylation produces an unbreakable covalent bond between the inhibitor and the enzyme protein. Now, enzyme activity is permanently blocked; even if all unattached inhibitor is removed. Aromatase enzyme activity can only be restored by new enzyme synthesis. Now, on the other hand, competitive inhibitors, called type II AI’s, reversibly bind to the active enzyme site, and one of two things can happen: 1.) either no enzyme activity is triggered or 2.) the enzyme is somehow triggered without effect. The type II inhibitor can now actually disassociate from the binding site, eventually allowing renewed competition between the inhibitor and the substrate for binding to the site. This means that the effectiveness of competitive aromatase inhibitors ***ends on the relative concentrations and affinities of both the inhibitor and the substrate, while this is not so for noncompetitive inhibitors. Aromasin is a type-I inhibitor, meaning that once it has done its job, and deactivated the aromatase enzyme, we don’t need it anymore. Letrozole and Arimidex actually need to remain present to continue their effects. This is possibly why Nolvadex does not alter the pharmacokinetics of Aromasin (11).

Conclusion

Before we close the book on Aromasin, it’s worth noting that you can (and should) still use one of the non-steroidal AIs during your cycle to reduce estrogen, if necessary. When you are ready for PCT, you can then switch over to Aromasin and still experience the full effects of an AI, since there is no cross-over tolerance experienced between steroidal and non-steroidal AIs (9). Since Aromasin is about 65% efficient at suppressing estrogen (10), it’s certainly a very powerful agent, especially considering you won’t experience reduced effectiveness because of your concurrent use of Nolvadex or from any sort of tolerance developed by using other AIs on your cycle(9). There is also a decent amount of preclinical data suggesting that Aromasin has a beneficial effect on bone mineral metabolism that is not seen with non-steroidal agents, and it may also have beneficial effects on lipid metabolism that are not found in the non-steroidal Letro and A-dex (9).

Finally, as we’re going to be using Nolvadex for PCT anyway, and we ought to be using an AI with it for maximum recovery…I think Aromasin- considering it’s compatibility with Nolvadex and beneficial effects on bone mineral content and lipid profile, has finally stopped being the black sheep of AIs and found a home in our cycles".


Your welcome

most suggest to .25-.50 liquidex on cycle to prevent gyno/water retention and then 25mgs of aromasin on PCT with nolva/hcg .

That's what I am doing.

HCG is unfortunately out of the question... its unavailable locally and im afraid to get scammed online

[FRANk THe TANk]

if lion dont carry it, i cant get it for pct

[chest6]

just gotta know where to look.

I've only seen HCG available domestically a few places myself..

Aromasin is carried by some research companies but I do not believe I am allowed to release that....
