Chemical Name: Tadalifil citrate Drug Class: Pro-Sexual Cialis (Tadalifil citrate) is essentially a much longer lasting version of the erectile dysfunction drug “Viagra” more or less. Most people are familiar with Viagra, and know that it provides increased blood flow to external genitalia (the penis) for approximately 6-8 hours, thereby helping to temporarily relieve erectile dysfunction. The major difference here is that Viagra can give you an erection for 6-8 hours, while Cialis is good for 36-48 hours. This makes it a much better buy, in terms of economics, as you are getting a window of opportunity that lasts substantially longer with Cialis. In fact, currently out of the three popular erectile dysfunction medications (Cialis, Viagra, and Levitra)- Cialis is easily the one which lasts the longest. Since my audience is primarily steroid using men, I’m going to guess that most of them aren’t having a problem in the erections department – unless it’s because they’re having too many of them! So what I really think Cialis is good for is men who (against my recommendations) have chosen to run “Deca only” cycles or “Tren only” cycles, and found that erectile dysfunction followed. Also, during PCT, Cialis is a good occasional choice, when you’re waiting for your natural hormonal levels to return. Although PCT is only (*typically) 6 weeks long, Cialis has been shown to be safe in treating erectile dysfunction for up to 6-months (1). In one study, improved erectile function and sexual intercourse success rate for those using Cialis was 73.5% (1). This may provide additional benefits during PCT, because lack of sexual activity due to erectile dysfunction can decrease testosterone levels through anl effect on the hypothalamic-pituitary axis (HPTA) (2). As you can expect, when you are having successful sex, your testosterone levels actually go up, and when Cialis was given to men for a month, and at the end, they had considerably higher testosterone levels when compared with their previous levels, probably because of this additional sex(2). One study indicates that you can use it for up to 3x a week (1). Since it lasts 36 hours each time, this means you are covered for the entire week, more or less. In addition, Cialis was well tolerated, had very few sides, and was very effective at increasing the success rate of sexual intercourse attempts (1)(3). I think that even if you’ve never has erectile dysfunction, Cialis is a good thing to have on hand during PCT. But hey, only if you enjoy getting laid. References: 1.
