On game descriptions, wiki, or source code, there is no explicit limit of penis size and testicle size of the goo player (with 3 or more GaloMax doses).
However, their volume grows in a cubic rate based on size increasing, resulting a growing requirement of biomass.
It turns out that there is a cap of penis size and testicle size.
For testicle size, it seems to be capped at about 2379.6 in (with 5 GaloMax doses); beyond that you need more than 900 L biomass to increase one step. However, Equilibricum can modify your goo testicle size. With this specific TF your testicle size can go as big as you want, not actually capped.
Penis size is more complicated. If you used some Tentatool Pill to get a 0.5x thickness before GaloMax, and use a Tapered-flagged penis type after GaloMax, you will have a minimal biomass requirement of same penis length. In this case the penis size is capped at about 6099 in (with 5 GaloMax doses); beyond that you need more than 900 L biomass to increase one step. There seems to be no TF working on the goo penis at this point (especially the Dicksprout for non-goo player).
(Are you satisfied with that big size? Anyway, I'm searching for a possible way.)
The biomass-cap logic also applies on goo breast. But there is already a hard cap on it. Fortunately Boobswell Pads and Honeypot perk still work.
