The Lou STP

by TG Supply


We designed this STP - The Lou, (in honor of Trans Trailblazer Lou Sullivan and a nod to the British term "loo" meaning bathroom) - to be extra urinal friendly. The angle of the shaft on this model points out rather than down, so it hits the urinal just right. 

We also made the cup rise up a little taller in the back in order to prevent potential spills.

The Lou is made with the same silicone as all other Transguy Supply STPs. The texture is hard enough to be effective in the bathroom but soft enough to bend for comfortable all day packing. If you are a fan of the EZ Pee or the Santos, you'll definitely want to check out this model. 

The Lou is smooth and soft to the touch. It's never sticky, even after washing, and will never need powdering.

Great Product

This was my first stp and it is super reliable. Nice material and after a little practice it was super easy to use. The bowl is pretty big and has good flow. Packs well and it’s pretty realistic for the price. Would definitely recommend especially if your not trying to pay a lot and still have good quality.

exactly what I am looking for

only take a few practice and good to go, suitable for packing if wearing a jock strap.

The lou review

My first stp, so far so good. It's soft, and you need to remember to ease up with the strengh of the urine stream

Nice weight
Fleshy, but not sticky texture
The balls act as a bowl
Good for packig
Pretty easy to use
Inexpensive, even with delivery

There's a flat spot where a small amout of urine gathers, so you need to remember to either lift the balls a bit, or tilt the whole stp down, but with pants it's quite challenging

Overall, very good as a first stp. I was especially pleased that it worked with my far-back positioned urethea. It's amazing that i found such a good stp with worldwide shipping and accecible price

Ho hum

Great as a packer but the area is too shallow and spills over .very disappointing .

Less firm than expected

Alrighty, So I’ll just start with I purchased the Mr Freely first and let me say the molding that injected into the top part the bowl / cup area that fits underneath my junk, it’s wayyy better than the Lou . The Lou is somewhat okay but and it’s obviously different for everyone, but I need more stability in the piece I am using everyday now if they made the Lou with the Same top as MrFreely that would be a one two knockout! Its so soft and way to smushy feeling now don’t get me wrong it’s comfortable but not sturdy enough. And as far as the shaft it’s good I like it but a little to thick . Especially for packing all day everyday. Work life all of it. I Think the Mr Freely is the best so far, if they just made the cup a wee bit more larger in size without comprising its integrity while urinating. Because yes we all have different streams mine is definitely on the stronger side even tho I practice tightening. I am older also so there’s a lot to take in account. But I’d love to see the Mr Freely made a wee bigger on the top nothing crazy . And the Lou well it’s going on the recycling useless to me and even though the price point is definitely good. I really dislike wasting money like that . I wish there was a way to recoup something. But that’s the way it is. So Thank you both over there for making this all possible and offering some great products! Keep evolving we Need it ! Vin
