You say it's wrong for a 18-20 yeard to juice because their too young and it will stunt their growth? This is factually incorrect.
Epiphyseal plate closure on average occurs at age 15 in girls(that't right, at 15 their completely developed) and in boys at age 17. Almost nobody nowadays grows until their 21.
What causes epiphyseal plate closure?
Tesoterone.... WRONG!
ESTROGEN! causes it. It's the aromitzation of anabolic androgenic steroids that causes premature epiphyseal plate closure. Simply use a dht derivative that doesn't aromitize and you won't closure the plates.
Small doses of steroids such as oxandrolone (which cannot aromatize
due to the fact that the A ring is a lactone) have been used to stimulate linear growth in prebubescent children (with minimal risk of virilization).
Cheaper than hGH and easier to administer.
BUT, It's not that simple. There are other hormones at play in the
developing skeleton than just testosterone, such as estrogen, growth
hormone, and IGF-1. They all interact in bone metabolism and
associated soft connective tissue (bone is also a connective tissue,
but referred to as 'hard' CT, versus the 'soft' CT of ligaments and
tendons).
Actually, Test has a biphasic effect: the initial effect is rapid bone
elongation resulting from the synergistic effects of three anabolic
hormones: GH, IGF-1 and T. Estrogen has the opposite effect (and it's
fairly rapid). Estrogen is also a key component of epiphyseal closure.
However, as with most hormones, the effects are biphasic. In other
words, the response during the initial time of treatment (acute) and
changes in response during long-term treatment (chronic). Acute T
administration causes accelerated bone growth (T has a GH-independent
effect on epiphyseal growth plate by upregulating IGF-1 receptors),
which then declines with chronic treatment.
Estrogen is similar, except that the initial effect of E is to inhibit
growth of the epiphyseal growth plate. Long term T administration
overrides the growth inhibition of E on the plates.
The other reason you state is that natural testosterone is through the roof when your a teenager
WRONG! There is no comparison between being on steroids and a slightly elevated testosterone blood plasma level in 18-20 year olds. A simple dosage of 10mg of d-bol causes a 5 fold increase in tests levels(posted in the profile section of this website)
There is no significant difference between test levels in the average 19 year old vs. 21 year old. The large increase in test are seen at ages 14-16 and even here there is no comparison to steroid use. Do you see balding 15 year olds? Again this is the average. Some males do grow till they are 19.
Under age 20, x-rays should be taken to make sure epiphyseal plate closure has taken place.
Age 20 and up... there is no risk. Your simply picking age 21 because that's the drinking age in the states and the "new" age of adulthood because of the extended adolescence were seeing in today's youth.
Were raising a bunch of adult babies who can't support themselves. Back in the day.. 18... your ass is kicked out. That's the way it should be.
It takes about 1.5 years to plateau in development when lifting. Distance yourself from the thought that you can gain serious muscle and strength from natural weightlifting after 1.5 years. First 6 months... enormous strength increase-- neural--- 6-1.5 years slight hypertrophy. On average 8 pounds with a person who knows exactly what their doing.
Finally, my recommendation is that everyone should wait until age 20 to start the juice, but STATE THE FACTS.
