Tadalafil (Cialis) 20 mg – 100 Tabs
Description
What is Tadalafil 20mg, 100 tabs (Astera Labs)?
Tadalafil at 20mg, 100 tablets. The same product as the 50-count, in double the quantity.
Also sold as Cialis, tadalafil or Adcirca.
Tadalafil is a PDE5 inhibitor. It relaxes the smooth muscle in blood vessel walls, which increases blood flow, and it does that everywhere rather than in one place. That is why the same compound is prescribed for erectile dysfunction, for enlarged prostate symptoms and for pulmonary blood pressure.
Tadalafil 20 (100 tabs) benefits
- Up to 36 hours from a single tablet, far longer than anything else in its class
- Food does not affect it, unlike sildenafil
- Can be taken at a low daily dose instead, so nothing has to be timed
- Improves symptoms of an enlarged prostate as well as erectile function
- Better blood flow means a noticeably better pump during training

Two approaches. 10 to 20mg taken when needed gives a strong effect across a day and a half. 5mg daily keeps a steady level so there is nothing to time at all.
For daily use, CIAMED 5 is 5mg per tablet and avoids quartering these.

Frequently asked questions
What can I not take it with?
Nitrates, absolutely and without exception. Heart medication such as nitroglycerin or isosorbide, and recreational poppers, which are amyl or butyl nitrite. Together with a PDE5 inhibitor they cause a catastrophic drop in blood pressure.
Alpha blockers for the prostate need care too and should be spaced apart. Grapefruit juice raises blood levels. If you take anything for blood pressure, start at the lowest dose and see how you react.
Will it increase my sex drive?
No. This is the most persistent misunderstanding about the whole class. A PDE5 inhibitor improves blood flow so an erection can happen and hold; it does nothing to libido.
If desire is the problem rather than function, this is the wrong product. That is usually a hormonal question, and testosterone, prolactin and estradiol are what to look at.
My erections went on cycle, will this fix it?
It will cover it, which is not the same as fixing it. Erectile problems that start during a cycle are usually hormonal rather than vascular, and a PDE5 inhibitor does nothing about the cause.
On nandrolone or trenbolone the usual culprit is prolactin, which cabergoline addresses. On a heavy testosterone cycle it is usually estrogen, either too high or crashed too low from over-dosing an aromatase inhibitor. Test before you treat.
Why does it give me back ache?
Back and muscle ache is the characteristic side effect of tadalafil specifically, affecting a minority of users. The usual explanation is PDE11 inhibition, which the other compounds in this class do far less of.
It typically arrives 12 to 24 hours after a dose and settles on its own. If it happens consistently, a lower dose or switching to sildenafil is the answer.
Daily or as needed?
Genuinely different approaches. A low daily dose keeps a steady level in your system, so nothing has to be planned and it is always working.
A larger dose taken when needed gives a stronger peak, but you are timing around it. Most people who use it regularly settle on daily.
