Yes 100% thats it but how does DHEA cause suppression (Hypothalamic-pituitary-gonadal axis)? Thats a big question. If it does then .... :shock: !!!!!
I'm with you on your products I'm arguing that this is PCT-based.
Prove me wrong.
Oh please remind me to remove my sig. ... its even annoying me.
I actually like your sig, lol!
Anytime you're introducing either an exogenous active hormone, or a prohormone into your body it, can/will cause endogenous hormonal suppression. Keep in mind that the degree can greatly vary due to many factors such as, the compound that's used (its pharmacological make-up being significant), the dosage applied, and the overall length of time taken.
DHEA will convert through steroidogenic enzymes (whether in the skin or the gi tract) to Androstenediol/Androstenedione, and then to Testosterone and/or Estrogen. You body's hormonal environment acts on a negative feedback mechanism in terms of its regulation/secretion. When there is an outside source contributing to serum testosterone and estrogen levels, your body will respond accordingly in an attempt to maintain homeostasis.
The hormonal negative feedback mechanism kicks into gear when it senses that exogenous forms of a circulating androgen and/or estrogen are being demonstrated. Aromatizable compounds demonstrate higher levels of circulating estrogen levels which tend to be more suppressive on the HPTA dynamic via the negative feedback loop. That's why many hormones that are not able to convert to estrogens have been known to be 'not as' suppressive to the HPTA dynamic (this does NOT apply to all compounds though; progestin based compounds also being a different ballgame in ways.)
Now as i said, there are many factors that can/will determine the degree of suppression. If your DHEA is used at a fairly low dose, or for a reasonably short amount of time, i doubt that any significant suppression dynamic would be present. I'm just speaking from the fact that DHEA will convert, and has the potential to suppress your endogenous production.
