SizePro Male Enhancement Pills Review

Review - Penis Enlargement
Endowmax was the most effective penis enlargement pill of the group. Endowmax effectively increase penis length, girth and firmness. The testers that used Endowmax experienced and average of 28% increase in size translating into on average 2 inches in size. They also experienced a marked improvement in sexual performance. We gave Endowmax a must buy recommendation.
Xytomax penis enlargement pills
Xytomax increased the length and girth for most of our testers. Our testers reported harder, longer-lasting erections, giving them a boost in sexual performance. Users of Xytomax noted a marked increase in libido. We rated Xytomax a must buy.
Xanogen penis enlargement pills
Xanogen turned out to be a great sexual enhancer, producing excellent erections for almost all of our testers and their sexual appetite increased as a result. Xanogen's average 1 inch increase in size was not satisfactory to our testers, so we gave it a tentative buy.
natural gain plus penis enlargement
Natural Gain Plus was one of the more expensive products of the group but it did have some interesting properties. Our testers experienced about a 1/2 inch growth which was respectable but not the kind of significant growth most of our testers desired.
Vimax came in last because some of our testers did not achieve any sexual enhancement results or penis size increases. However, about 50% of the test group did achieve about a 1/2 inch growth in size. So apparently this formula was effective but it was hit or miss depending on the user.

SizePro Male Enhancement Review

Rated: 81 out of 100

Orexis product reviewSizePro is a relative newcomer in the field of male enhancement products. SizePro is marketed by Health Solutions of Post Falls, Idaho. With its attractive blister packaging and promises of fast and easy male enhancement, SizePro fit right in with the other male enhancement products we reviewed.

The SizePro also states that their product is "Doctor Recommended." Upon further investigation, we learned that the doctor in question is a psychologist! This is misleading at best. We feel that any doctor in a position to recommend a penis enlargement pill like SizePro should be a urologist, or at best a general practitioner, rather than a psychologist.

Another strike against SizePro was the requirement of a "maintenance dosage." It is sometimes the case that, in order to keep the gains in penis size caused by a formula like SizePro, a man must continue to take the pills indefinitely. This leaves men in a quandary: is it better to continue to take (and pay for) SizePro, or stop taking it and see their penises shrink back to normal?

We took all these factors into account when evaluating SizePro.

Notes on SizePro:

SizePro is a one-pill-per-day formula, something that appealed to many of our testers. The SizePro website recommends taking the pill one hour before intercourse for best results. This is somewhat difficult to plan in reality, however, and not something many of our testers were able to accomplish.

The SizePro formulation does not contain yohimbe and is therefore safer for men suffering from hypertension or cardiac issues. However, you should always consult a doctor before trying herbal supplements if you suffer from health issues. (Unlike the makers of SizePro, however, you should consult a medical doctor rather than a psychologist.)

SizePro Reviews

Many SizePro testers reported a boost in sexual desire after a couple of weeks taking the product. This enhanced libido trailed off after 6-8 weeks on the program. Afterward, men did not report a significant difference in sexual desire or performance. It is possible that the dosages of active ingredients are so low that tolerance is quickly reached, or perhaps the SizePro formula is metabolized more quickly by the body than other male enhancement products we reviewed. (Or perhaps it has to do with all the extra ingredients in SizePro? See below for more.) Unfortunately this question is out of the scope of this study.

SizePro did increase the length of the penis by 3/8 inch on average, about 1/8 inch per month. It is possible that a six-month course of SizePro pills would gain 3/4 inch in size, but this is far below the results we saw with other male enhancement products.

Our testers were generally unsatisfied with this product. Several complained about its lack of effectiveness and several speculated, aloud, that we were giving them placebo rather than true SizePro. This was not the case.

Based on these results, we do not feel comfortable recommending SizePro. There are other male enhancement products that boost male sexual performance as well as sexual desire and penis size (specifically the top-rated product). Therefore, SizePro received a do not buy recommendation.

SizePro Ingredients

The complete SizePro ingredients are listed below.

Vitamin E, Niacin, Hawthorn Berry (crataegus oxycantha), Horny Goat Weed (epimedium sagittatum), Damiana Extract (turnera diffusa), Muira Puama Extract (ptychopetalum olacoides), Ginkgo Extract (ginkgo biloba), Chinese Ginseng Extract (panax ginseng), Tribulus (tribulus terrestris), Catuaba Extract (erythroxylum catuaba), Saw Palmetto Extract (serenoa repens), inosine (hypoxanthine riboside) Oat Straw Extract (avena sativa), Cayenne (capsicum).

Note that while SizePro does contain the potent tribulus terrestris, it doesn't include the other most powerful ingredient, Xanthoparmelia scarbrosa. We feel that the inclusion of Xanthoparmelia would go a long way to increasing the effectiveness of SizePro pills.

In addition, SizePro contains a staggering list of inactive ingredients:

Calcium carbonate, dibasic calcium phosphate, tribasic calcium phosphate, microcrystalline cellulose, fructose, dextrose, sucrose, maltodextrin, croscarmellose sodium, stearic acid, magnesium stearate, silicon dioxide, xylitol, sucralose, natural and artificial flavors, acacia gum, shellac, sodium lauryl sulfate, sorbitol, gelatin, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxypropyl ethyl cellulose, pharmaceutical glaze, food glaze, starch, talc, titanium dioxide, vegetable oil, FD&C Red 40, FD&C red lake, FD&C blue 40, FD&C blue lake, FD&C yellow 40, FD&C yellow lake, water.

There is absolutely no reason for this catalog of inactive ingredients. Not only does the large number of synthetic ingredients raise questions about the potential for harmful effects (shellac?), it drives up the cost of the SizePro formula. We do not recommend using SizePro due to this large number of unnecessary ingredients found in SizePro.
