The researchers proposed studying the effects of guyabano leaf extract in enhancing growth hormones in teenagers. Many parents use commercially made vitamins to stimulate growth, but guyabano may be more effective and affordable. The study would involve teenagers drinking guyabano extract or a commercial product daily for 7 years to compare effects on height. Researchers believe guyabano contains nutrients that could boost growth hormones. If successful, guyabano extract could be recommended as a natural growth enhancer that is accessible and has no side effects.

4. INTRODUCTION
In the past few years, parents
dedicated their trust in a commercially
made vitamin to stimulate the growth
hormones of their kids. But these
nutrients are not enough to sustain their
body needs. That leads them to some
hormonal deficiencies.

5. INTRODUCTION
Now, the researchers believed that
the guyabano leaves extract (Annona
muricata) is the answer to their problem.
It is packed full with all weight-
promoting and cell-nourishing nutrients
such as calcium, iron, vitamin B-
complex, and vitamins A, D, and C which
plays a vital role in enhancing the
growth hormones of most teenagers.

6. STATEMENT OF THE PROBLEM
Generally, the purpose of this project
proposal is to help the teenagers to
activate their growth hormones in this
stage of puberty to be able to achieve
their aimed height.
Specifically, the purpose of this
project proposal is to test the potential of
Guyabano leaves extract (Annona
muricata) as a teenagers’ growth enhancer
if it’s really effective

7. HYPOTHESES
Ho: There is no significant difference
that exists after the intake of
Guyabano Leave Extract in enhancing the
growth hormones of teenagers.
H1: There is a significant difference that
exists after the intake of
Guyabano Leave Extract in enhancing the
growth hormones of teenagers.

8. SIGNIFICANCE OF THE STUDY
When it comes to enhancing the growth
hormones of their children, parents have learned to
trust in commercially made vitamins over the years.
But some families who are in lower socio economic
status unfortunately cannot afford to buy these
growth enhancing products. BUT NOW, GOOD NEWS
AWAITS EVERYONE! The researchers believed that
Guyabano Leaves Extract (Annona muricata) has a
growth potential. It’s the ideal companion of parents
who are looking for affordable yet effective growth
hormone stimulating supplements for their kids.
It will also contribute to the advancement of
science aside from it has no side effects in the body
when you take in and the raw materials can be easily
obtain anywhere all year round, it will not also
destroy the conservation of our natural environment.

9. SCOPE AND LIMITATIONS
The researchers of this project proposal,
together with Mrs. Mechel S. Banzon as the research
adviser will conduct this study to determine the
growth potentials of the substances present in
Guyabano leaves extract in the enhancement of
teenagers’ growth hormones.
The researcher will gather the acquired amount
of Guyabano leaves, as well as the other important
materials needed in conducting the study at the
nearest possible source.
This study will be conducted at San Jacinto
National High School, Guibel, San jacinto, Pangasinan,
ang will begin on the 1st week of November and will be
expected to end on the last week of December.

10. DEFINITION OF TERMS
Adolescence – the duration of physical
and psychological boost for intersection of
puberty and maturity.
Spurt – a rapid short burst as of
energy, activity, or development.
Rapid Growth Rate – the frequency
with which the proliferation or growth
occurs per unit of time or other standard of
comparison.

11. METHODOLOGY
A. Materials and Procedures
150 grams of Guyabano Leaves will be gathered
at the nearest possible source. Wash the leaves until
all the dirt is removed, after which, it will be chopped
into pieces to release more the substance inside the
leaves. Wash the casserole thoroughly to avoid
contamination that will affect the study. Put the
leaves inside the casserole with 1500 ml of water. The
researcher will get the extract of guyabano leaves by
decoction, for 15 minutes, decoction is the process of
boiling a part of a plant to produce its extract.
Lastly, put the extract in a clean container using a
strainer. The researcher will add a small amount of
sugar to give a pleasing taste to the guyabano leaves
extract. It can be served whether hot or cold. Drink
thrice a day or more.

13. DURATION AND SCHEDULE OF ACTIVITES
ACTIVITIES NOVEMBER DECEMBER
1. Conducting the experiment *
2. Preparation of the variables to be used
* *
(Guyabano leaves and two teenagers)
3. Gather guyabano leaves at the nearest
possible source and a commercially made * * *
growth enhancer (cherifer)
4. After gathering the guyabano leave, follow
its methodology to come up with a product
* *
which is the guyabano leaves extract by the
process of decoction.
5. The teenagers will be drinking the controlled
variables which are the guyabano leaves
* *
extract and cherifer to compare and tests its
effectiveness.
6. Observe its effectiveness and gather relevant
* * *
data regarding it.
7. The growth of the teenagers will be at least 7 years as its duration. So, the
experimentation will take too long. It will also take 7 years to accomplish the study.
As the teenagers will grow taller, its effectiveness will be compared to the
commercially made. And as the time goes by, its effectiveness will be proven, if ever.
