How much filler will I need?

Estimate Only

There is variation from patient to patient, so we have provided conservative estimates.

Based on measurements of approximately 1,200 patients.

Thickness Increase Estimate 20ml

4 Inches
1.1
5 Inches
0.9
6 Inches
0.8
7 Inches
0.7

The amount of girth gained depends on the starting length of the penis and the amount of penis filler injected.

A shorter penis will require less filler, and therefore less cost. Conversely, a longer penis will require more filler.

The increase in girth is noticeable during sex for both you and your partner.

We strongly recommend testing your new girth with any long-term partner before opting for any additional size gains.

Further injections can be provided at a follow-up appointment as soon as two weeks after the initial procedure, if additional girth is desired.

The safest and most effective approach is to add girth cumulatively, in manageable steps and with repeat visits, rather than an ‘all in one go’ approach.

As the recovery time is relatively short, it is not a major inconvenience to have a small amount of additional filler on a subsequent visit should that be desired.
