Many herbal and vitamin supplements in the market claim to be a natural alternative to Viagra, but most of them fall short of the tall promised results. This is a review of three OTC male enhancement pills used to boost erection size and libido; Stiff Nights, Stiff 4 Hours, and VigRX Plus. Please note my conclusion below the table for some important notes about the safety of the “Stiff” pills.

So, which is the best herbal Viagra; Stiff Nights, Stiff 4 Hours or VigRX Plus?

First of all, there is no such thing as an “herbal Viagra”. The drug Viagra (sildenafil) is an FDA-approved treatment for erectile dysfunction and it works for most men with erection problems. There is no OTC substitute that works as fast or effective as Viagra, but there are some herbal remedies that can help to some extent.

A lot of customers seemed to be happy with the results of the “natural” supplements Stiff Nights and Stiff 4 Hours. Until it turned out they are not really natural! The FDA investigated Stiff Nights pills and found that it contains hidden prescription drugs. So, the company stopped making Stiff Nights a while ago. Then the Stiff 4 Hours brand came out, which has also been busted by health care authorities as it contains undeclared prescription-only drugs.

Neither Stiff Nights nor Stiff 4 Hours is as safe or natural as advertised. The undeclared drugs in these two pills can cause serious side effects and interactions for some consumers. Stiff Nights has been pulled from the market, and the same applies to Stiff 4 Hours (some stores may still be clearing out their stock).

VigRX Plus Authentic Box VigRX Plus is a different story. This is truly an herbal supplement that contains the listed ingredients. This brand has been in the market for more than a decade with over 6 million users and it is one of the decent supplements that you can use for a boost in penile circulation and libido. If you are looking for an OTC sexual enhancer, I suggest you try VigRX Plus as it contains a multi-herbal formula of the most potent herbs used for sexual enhancement.

If you are looking for a long-term fix to your sexual potency, erection quality, and libido, then I’d vouch for VigRX Plus. All in all, VigRX Plus is a good consideration for non-prescription male enhancement. It works wonders, and is comparable to Viagra in terms of efficacy, but for a dietary supplement it provides an amazing dose of sex-enhancing herbs.
