Trans Masc Pump Deluxe

Gender euphoria in every box.

Our bestselling FTM Pump kit, and the one people reach for when they want room to grow. Three custom-molded cylinders in graduated sizes mean a fit that's right for you today, with space to grow into tomorrow. Start where you are. Grow into what's next.

We're the creators of the Trans Masc Pump. We've invested tens of thousands in R&D and created molds made for our bodies. Most pumps on the market use cylinders made for nipples. Ours are molded specifically for bottom growth — a different anatomy, and a different experience. Better seal, better fit, better results. Products designed for you — because you deserve it.

What's Included

• 3 graduated cylinders — custom-molded for bottom growth anatomy, not repurposed nipple pumps
• Translucent cylinders — see results in real time, instant visual feedback
• Manual pump — total control at your own pace, no batteries, no complexity
• Works pre-T & post-T — solo or with a partner
• Optional adhesive ruler stickers — track your journey if you want to. No pressure, no expectations

How your Deluxe ships right now

Through August, the Deluxe ships as a component kit: the same manual pump, all three custom-molded cylinders, and the measuring stickers — packed as parts instead of the retail box while our new packaging arrives. Same everything, same warranty, ready to use. Some transition kits even include a bonus cylinder (4 total).

Pairs perfectly with Jack for a complete trans masc experience.

Always use with lube.

Your questions, answered

A manual pump uses a hand bulb you squeeze to create suction — you build and release the vacuum yourself, at your own pace. No motor, no battery, nothing to charge. The translucent cylinders let you see what's happening the whole time.

Control and simplicity. With a manual pump you feel exactly how much suction you're applying and can stop instantly. It's quiet, travel-friendly, nothing to charge, and costs less. If you'd rather see an exact pressure number and go hands-free, that's the electric Pro Pump — but many people prefer the tactile control of manual.

Start snug but comfortable — a good seal matters more than size. Most people begin with the smallest cylinder that fits without pinching, then move up as their body responds. That's exactly why three graduated sizes are in the box. Full fit guide: What size pump cylinder do I need?

Start gentle — soft fullness, never pain, numbness, or color change. A few light squeezes is plenty at first; if it aches, release and go lighter. Keep early sessions to 5–10 minutes.

Same manual pump, different range: the 2.0 comes with one custom-molded cylinder — the simplest start. The Deluxe includes three graduated sizes, so you have room to grow without buying again. If you expect to size up, the Deluxe is the better value.

Yes — it's the same simple manual pump as the 2.0, just with three sizes so you're never boxed in. Nothing to configure; start with the smallest cylinder and gentle pressure.

No T required — pre-T, post-T, or never on T, it meets you where you are. Start with 2–3 sessions a week, 5–10 minutes each, and build up slowly. Recovery between sessions is part of it.

Session effects are reliable: fullness and heightened sensitivity show up right away. Long-term change varies by body and no one can honestly promise it — the included measuring stickers let you track what's real, not what marketing says.

Always a plain, unmarked box — no logos, no product names outside. Your card statement reads New York Toy Collective.

The science behind pumping

Bottom growth is driven mostly by testosterone. Androgens act on receptors in genital tissue to enlarge the clitorophallus — a well-documented effect that's most rapid in the first year on T (Grimstad et al., Andrology, 2021).

Where a pump comes in: blood flow. Vacuum devices use gentle negative pressure to draw blood into erectile tissue and raise the oxygen level in it — the same mechanism used in penile-rehabilitation medicine (Lin et al., Asian Journal of Andrology; Yuan et al., International Journal of Impotence Research). More blood flow is what produces the temporary fullness and heightened sensitivity you feel during a session.

Our honest caveat: that vacuum research was done on cis men for erectile function — no one has run a long-term study on trans masc bottom growth specifically. What's solid is the session effect (blood flow, fullness, sensitivity). Lasting change varies by body, and anyone who guarantees inches is selling you something. We include measuring stickers so you can track what's real for you.
