John explains that the formula is not perfected!!! It take three dosages to make a large permanent increase in mass. The first does will cause considerable growth of between 100 to 200% but after 48 hours the experiments only retained 10% permanent growth.
Second does will cause a 50% retention of even greater growth. Last dosage causes a 90% retention of size. Also this version is made to increase cow's udder size so she should expect some breast growth!
She say's I could use a little more up top! The girl who won my Job was huge and really busty. I think she was around you height John. She takes the formula and drinks it with just a moment of hesitation.
