Teslac is one of the very first drugs approved by the FDA to fight estrogen-dependant breast cancer, back in 1970. It does this by possibly inhibiting the aromatase enzyme in what appears to be both a noncompetitive and an irreversible manner.
I have to admit, when I first went to research this compound, I had thought I was researching a useless old Anti-Estrogen. I took a quick look at its chemical structure, and realized that it was actually an anabolic-steroid! Oddly, its D-ring (usually pictured as the upper-right hand ring in models) is a weird 6 memberes lactone ring, instead of the usual 5 ring one that testosterone has. SO& now I know its an anabolic steroid& but what kind? And what would it do? Primarily, its an Anabolic Steroid which has made its claim to fame by being used primarily for its antiestrogenic effects (much like proviron), and I think that its been wrongly assumed to be simply an antiestrogen by many athletes. This is not the case, and as youll soon see, theres really no reason why this stuff has been pushed out of use by bodybuilders and athletes for the last decade.
The first study I looked at (1) showed that Teslac increases testosterone (by 47%) and its precursor androstenedione (70%) levels in the body. In the second study I looked at, it raised testosterone levels in men up to 290ng/dl (almost enough to bring you from 0 test to the lowest end of normal/acceptable range), as well as raising LH (leutenizing hormone) levels, and even FSH (Follicle Stimulating Hormone) levels slightly (2). So as you can see, not only is this stuff not suppressive of your natural hormones, it actually stimulates your body to produce more testosterone as well as the hormones which produce it.(2) As for its ability to halt aromatization, it has been shown to reduce it by 90-95%, with regards to decrease in the overall rate, in some instances (7). In another third study, Aromatase inhibition by testolactone, at a dose of 500 mg twice daily (so a total of 1,000mgs/day) for 4 weeks lowered circulating estradiol (E2) levels by roughly 1/3rd and enhanced the secretion of follicle-stimulating hormone and testosterone by approximately the same amount (1/3rd each)(6). Basically, were looking at pretty decent reductions in both aromatization, as well as reduction in total estrogen floating around your body. So far, we have seen that, in different studies it has been shown to increase LH as well as FSH, respectively, and in addition it raises testosterone levels and lowers estrogen levels in all of the studies weve examined. Raising FSH, LH, and testosterone while lowering estrogen is a pretty good deal considering most steroids lower endogenous (natural) production of the first three, and raise estrogen.
In fact, Ill go so far as to say that if you dont want to do any shots (injections) during your Post-Cycle-Therapy (PCT), Teslac may be perfect for you, since it will raise LH as well as HCG in most cases! And it has the added benefit of not desensitizing your leydig cells as much as HCG has the potential to do. Another important benefit of using Teslac over HCG during your PCT is that HCG actually may raise estrogen levels and/or act as an estrogen in certain tissues (8) (9), while we know that Teslac lowers estrogen levels and acts as (of course) an androgen.
This means, of course, if you are one of those people who are inclined to bridge (use a low dose of an anabolic compound between higher dose cycles), then this is perfect for you. In addition, youll be able to use Teslac during a cycle as an ancillary compound which will eliminate aromatasation.
Possibly the most exciting thing I read about Teslac is that it has been PROVEN (!) to be an effective and safe treatment for Gynocomastia(3) (development of breasts in male mammary glands& often ineloquently referred to as "bitch tits" in gym-speak). So yeah, if you get a bit of Gyno on a cycle, you may want to include Teslac in your PCT for both the (very good) reasons I revealed above, as well as its potential to treat your gyno.
The only prohibitive thing about Teslac is cost. Currently, I dont know of any online pharmacies who carry it,nor UG Labs& and it generally sells for anywhere between a dollar and $5 for a 250mg tab. If theres anything preventing this stuff from becoming the "must have" drug for PCT overnight, its the cost.
