Testosterone Replacement Therapy - aka “TRT”: Understanding the Method to the Madness and the Different TRT

OptionsAs we age, we all lose hormones that are responsible for healing and repair

these hormones are collectively known as “sex-steroids”-testosterone,estrogen

the only steroid hormone that goes up with age is the one most responsible for tissue break-down, lack of healing, and “getting old”; CORTISOL

Page 3: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Overall Goal of TRT: Although it is often known as “Replacement” therapy the actual goal is “Optimization”. Typical TRT aims to raise

testosterone to the “youthful” levels of a 30 year old healthy man.

• Overall Purpose of HRT: To balance and restore the natural hormonal ratio in the body so that the accelerated “break-down” that occurs with aging is partially reversed towards “healing and repair”.

• The end RESULT: Better mental and physical function, restoring, improving and sustaining a higher quality of life, and most importantly - decreased risk of age-related disease and illness.

Testosterone to Estrogen Ratios In Aging

Men

Total Testosterone Lab Reference Ranges (most labs) = 300-1100ng/dl

Typically as High as 50:1 In Healthy Young Males Who Are Reasonably Lean

and Fit

TRT: Restoring Optimal Testosterone Levels - Known to Be Effective for Reversal of Quality of Life Issues Pertaining to Physical Strength, Vigor, Energy, Libido and Overall

Testosterone Replacement Therapy (TRT) ‘corrects’ T-levels back within the known optimal range.

A handful of hormones work together with testosterone to promote optimal metabolism, energy, and overall well-being.

The most significant are: Growth Hormone (GH), Thyroxines (T3,T4), Adrenal Hormones, and Insulin

Many of the ‘age-related’ quality of life issues directly or indirectly relate to a deficiency of one or more of these hormones

Each of the hormones listed above can be a separate topic but the take home point is: ALL function best when the body has a “high-healthy” testosterone level

Page 6: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Bottom Line Take Home Point:

Cortisol is the body’s chief “tissue-break-down” hormone. As we age it is the only ‘steroid’

hormone in the body that INCREASES.

Testosterone is the MALE body’s chief “tissue-build-up and repair” hormone (along with GH and

something else called IGF-I).

With Aging Comes a Progressive Decrease in Testosterone and an Increase in Cortisol Which Accelerates the Aging

Process By Impairing the Body’s Ability to Heal and Recover from Stress of all types.

Option #1: Transdermal Testosterone Formulations (i.e. creams/gels)

How They Work Explained in 3 Simple Steps

Step 1: “Percent Strength” = the general potency of a T product expressed as a fraction. Remember the % symbol means “divided by 100”. ex. 5% T gel = 5/100.

Step 2: “Testosterone Delivered” - the amount or quantity of T contained in a single dose of a specific formula or product

Step 3: “Percent Absorption" - amount of pure T that is absorbed by the skin into the body

*****Note: author discourages creams/gels (collectively called ‘transdermals’ - if at all possible to use injections for the client/patient

Page 8: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Step 1 of Understanding T Gels and Creams: “TOTAL STRENGTH”:

def.* = *the total amount of testosterone contained per “dose” of product (as listed on the product label)

Most products on the market contain anywhere from 1g up to 10g of Testosterone per dose of of product

Most common are 5g, 7.5g, and 10g “total strength” per dose of product

Page 9: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Step 2 of Understanding T Gels and Creams: “PERCENT STRENGTH”(or CONCENTRATION)

The “CONCENTRATION” of the product - similar to how alcohol concentration in beer is 3-6% alcohol, gives us the quantity of testosterone in each gram of product

percent strength varies from 1-10% for most commercial versions, brands, makes, etc.

1% = closer to female products, 10% = closer to male products

Page 10: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Step 3 of Understanding T Gels and Creams: Testosterone “Delivered”:

The simplest way to understand this is to multiply the number in Step 1 by the number in Step 2. Total Strength x percent strength = Testosterone Delivered

def.*= “the quantity of testosterone actually rubbed onto the skin.” ex. 10% T cream at 10 GRAM “TOTAL STRENGTH” = 100mg of pure Testosterone “Delivered” to the skin surface

Ex. 1: Testim: one of the main US commercial T-gel products contains 5g of total testosterone per dose of product and has a 1% CONCENTRATION. 1% of 5 GRAMS = 50mg. Therefore a single dose of Testim “Delivers” 50mg of testosterone to the skin surface.

Page 11: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Step 3 Continued: another T product example: AndroForte (Australian

brand)

They make it simple and give you the T “DELIVERED” right on the label...

product comes in 2 different potencies: each 1 milliliter (ml) giving 20mg Testosterone for the 2% product, and 50mg Testosterone for the 5% product.

Page 12: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

The Fun Part - Making the Math Count: Absorption Through The Skin - Quick and Easy Calculation

Method (hint – its always 10%!)Take the TOTAL STRENGTH and multiply by %STRENGTH to get Testosterone Delivered.

ex. 1% = 5 x .01 = .05 GRAMS or 50mg Testosterone Delivered.

10% is the Standard absorption for T products through the skin

50mg (DELIVERED) x .10 absorption = 5mg absorbed into the body (healthy young men typically produce 6-8 milligrams per day)

Second Main Option for TRT: Intramuscular (I.M>)Testosterone Preparations (author

preferred)Carbon Chain ‘Esters’ yield the half-lives of various oil based solutions (hydrophobic)

Half-lives range from as little as three days (propionate) to as much as 3 weeks or so in the literature (testosterone undecanoate)

Quantity is measured in cubic centimeters (cc’s) or milliliters (ml’s) (1cc = 1mL) and strength range from as low as 50mg/ml to 250mg/ml and higher in some ‘underground’ preparations

Many Docs still dose TEST far too low to have an effect and can actually LOWER the Baseline level by inducing negative feedback

Page 14: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Massive amounts of misinformation based strongly on opinion has propagated a field of pseudo-science

that has evolved into ‘subjective fact’ All testosterones ultimately become the EXACT same form once the enzymes in the blood remove the ‘shell’

the ‘shell’ is often known as an “Ester” - a chain of carbon atoms attached to the TEST molecule at a specific functional position to make it last longer in a hydrophilic (water loving or water-based environment etc. - blood)

These carbon chains or tails attached at the “roof-top” or 17th beta position of the TEST molecule are more commonly recognized by terms such as propionate, enanthate, cypionate, decanoate, etc.

These are chemistry terms describing the # of carbons in the chain

Page 15: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Testosterone Injection Rules: #1 and #2:

English Please? Sorry, that is the correct way to say it - in layman terms the longer the ester chain (i.e. # of carbons) attached to your TEST formulation the longer it will last in your bloodstream

Why? Purpose of ester is to slow absorption of TEST into the bloodstream from minutes to hours, days and weeks.

You don’t have to be a chemistry wiz to know that a longer chain of carbons is p-r-o-b-a-b-l-y going to weigh more than a shorter chain...

Although this is a simple concept, the truth and accuracy of this topic has been slaughtered on the internet blogs, forums, and article postings.

1. The Length of the “Ester” is #1 factor influencing the half-life of the drug. An ester is made up of a “carbon chain”.

2. Just as the length of a chain is determined by the number of individual links it has in its physical structure, the life of the testosterone ester is determined by the number of ‘carbons’ it has in its structure.

RELATIVE POTENCY? The weight of a single TEST molecule (molecular weight) divided by the total weight of the TEST + ESTER

Remember we said earlier that the longer the ester the longer it lasts in the body - this is by design, and is the sole purpose of the ester (think more links, longer chain)

Recall that we also mentioned that longer carbon chains weigh more than shorter carbon chains - ex. Cypionate (8 carbon ester chain is heavier than propionate (3 carbon ester chain)

Does this mean that the longer lasting TESTOSTERONE products are...Less Potent than the shorter acting ones? Answer: ON a mg per mg basis – ONLY…YES. This is by simple math - addition and subtraction

Page 18: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Example: Testosterone Enanthate

Long, heavy ester 8 carbons in length

69% Testosterone

Comes in 100mg/ml, 200mg/ml strength on the general market

Simple Math says 69 or if we round up, 70 of every 100mg of TE is actual ‘pure’ Testosterone

Page 19: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Testosterone Cypionate

If we round up after the decimal, TE and TC are the same % testosterone

TC is a bit heavier than TE 420 vs 418 Daltons

This will equate to an insignificant 2mg difference between products which makes them interchangeable

Page 20: 3 testosterone replacement-therapy-client-intro-basics-october1st,2012

Testosterone Cypionate(TC): The Most Commonly Prescribed Testosterone Formula in the US

Testosterone ester formulations are abundant internationally and some of these preparations offer convenience, efficiency and better overall quality of life benefit than TC

The laboratory process of attaching the ester(s) is a simple one for any trained lab chemist and is very inexpensive - probably less than $50/month to maintain for the average TRT dose range of 200-300mg every 7-12 days

Society here in the US along with media propaganda and the American fascination with “Steroids” has created red tape preventing all but a handful of less effective products from being ‘scripted’ by US Docs
