Probe Thick and Rich is my all time favorite lube for many reasons. Sure, it's rich and thick (even more so than Maximus), but it's an absolutely no bullshit product. It's been around since 1981 and made in the same Portland Oregon based Darvyran Labs who have supplied clinics, doctor's offices and better quality sex emporiums. For a good reason too - it's a stellar product. Darvyran cares about their reputation. (Got questions, they welcome your calls at 1-800-637-7623 )

Before I put anything on or in my body, I want to know what it's made with, how it feels viscosity wise, if it stains, stings, or has any deleterious chemicals. I buy Probe because it meets stringent requirements.

Probe, Thick and Rich is manufactured in a licensed laboratory that regularly subjects itself to microbiological testing by other independent labs for purity.

Probe Thick and Rich is a simple formula - it's greater than 90 percent deionized water, less than 10 percent silky glycerin from a vegetable source for moisturization, less than one percent polyetheline oxide - an FDA approved, inert polymer. It holds onto water and slowly releases the water with friction. Its preservative is less than one percent grapefruit seed extract that is used to inhibit the growth of micro-organisms.

Probe's pH is 6.5 to 7.5. It spermicidal activity is 100 percent killed in a test tube. (This does not make it a spermicide intra-vaginally. )

Probe only lists on its package information that it may kill some sperm and not to use if your goal is conception.

In Draize skin irritation levels it rated 0.32 -virtually non irritating to the skin or vagina. It is also safe for oral ingestion.

Probe has a shelf life of approximately 5 years. It comes in a peach and white rather boring plastic container with a rather air tight dispensing lid. It's very discrete looking, like hand lotion.

Probe does not stain clothing, sheets or carpets. Its instructions are in both French and English.

I found Probe Thick and Rich to be close to odorless and tasteless. It's a bit thick and stringy. It does allow you a lot of play time, and it works well with toys, condoms, anal toys. It is not at all sticky, either. It's something you need to put on your must try list. Because it stays moist and not slippery for an extended time, it's great for handjobs, anal, condoms, dildos, putting bullets into toys, and genital massage. Great for peri and postmenopausal women and Transmen who have less natural lubrication and are more prone to problems with friction and dryness.

For the price, you can not get any thicker, longer lasting or more pure. Its pure enough for clinic use. So what if it's a little stringy. The pH is perfect and really, everything in life has its proper pH or its world goes haywire and chaos occurs. Better than KY or Walmart's Equate.
