What is Sildenafil Citrate 100mg, 50 tabs (Astera Labs)?
Sildenafil at 100mg, 50 tablets. The full standard dose of the most established compound of its kind.
Also sold as Viagra or sildenafil citrate.
Sildenafil is a PDE5 inhibitor. It blocks the enzyme that breaks down the signal telling blood vessel walls to relax, so vessels stay open and blood flow improves. It works on vessels throughout the body rather than in one place, which is why the same molecule is also prescribed for pulmonary blood pressure.

- The most established compound of its kind, with decades of use behind it
- Short enough that it is out of your system the next day

Sildenafil 100 dosage
- Starting dose
- 50mg, half a tablet
- Standard
- 50 to 100mg
- Maximum
- 100mg, one tablet
- Onset
- 30 to 60 minutes
- Duration

- Once in 24 hours
Start at half a tablet. 50mg is the dose most people settle on and side effects scale with dose, so there is nothing to gain from opening at 100mg.
Take it on a relatively empty stomach. A fatty meal delays and blunts it, which is the commonest reason someone concludes a tablet did not work.

Who is Sildenafil 100 (50 tabs) for?
Anyone who wants sildenafil at a normal working dose rather than the low strengths. Splitting these gives you 50mg, which is where most people land.
The 100-tablet sachet is the same product in double the quantity. If you would rather not plan around timing at all, tadalafil lasts up to 36 hours.
Before you run it. Never take this with nitrates. That means heart medication such as nitroglycerin or isosorbide, and it also means poppers, amyl or butyl nitrite. The combination drops blood pressure catastrophically and people have died from it. If you take anything for angina, this compound is not available to you. Headache, facial flushing and a blocked nose are the common side effects and they scale with dose. Sildenafil specifically can produce a blue tint to vision at higher doses, which is harmless and passes.
A fatty meal noticeably delays and blunts it, so take it on a relatively empty stomach. It also does not create desire. A PDE5 inhibitor opens the plumbing; arousal still has to come from you. Taking one and expecting something to happen unprompted is the single most common disappointment with this class.
If your erections went during a cycle, this may be treating the wrong problem. Erectile trouble on nandrolone or trenbolone is usually prolactin, and trouble on a heavy testosterone cycle is usually estrogen too high or crashed too low. A PDE5 inhibitor covers the symptom while the cause carries on.
Test prolactin and estradiol, and read the
estrogen management guide, before assuming the problem is mechanical. An erection lasting more than four hours is a medical emergency, not a good outcome. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
How to use Sildenafil 100 (50 tabs)
Swallow with water on a relatively empty stomach, around an hour before you need it. Half a tablet is a full starting dose. No more than one tablet in 24 hours.
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.
Sildenafil or tadalafil?
Sildenafil if you want something that works for an evening and is gone by morning, and if you would rather it did not linger. It comes on in half an hour to an hour.
Tadalafil if you would rather not plan around it. It takes about two hours to come on but lasts up to 36, and it can be taken at a low dose daily so there is nothing to time at all. Food does not affect tadalafil; it noticeably affects sildenafil.
Does food affect it?
Yes, more than people expect. A large or fatty meal slows absorption considerably and blunts the peak, so it comes on late and weaker.
Take it on a relatively empty stomach, an hour or more after a light meal. This is the commonest reason someone concludes a tablet did not work.
