Test - Dosing amounts between methods

[Kroms_laugh]

This is mentioned in passing in "Recipe for Success"... but I was wondering why Transdermals are given in 35mg (approx.) over a week, whereas 100mg Cypionate (70mg of which, are actually introduced to the system) are used for IM injections?

I understand that the body reacts differently to exogenous test, but why for transdermals is 35mg delivered when 70mg is delivered for weekly IM injections?

Where I got this;

When considering dosing of testosterone cypionate, it is important to remember that, due to the weight of the cypionate ester, a 100mg injection delivers, at best, 70mg of testosterone. This is important to keep in mind when comparing the effects of a 100mg weekly injection of test cyp to the 35mg total dose provided by Androgel 5gms QD over the same period.

The transdermal at that level will get you in the "normal range" which is good enough for most Dr's. Were as the cyp at that level will put you more at the top of the range, which is were more progressive Dr's like to see the T levels.

It's a good question. There are a lot of things to consider when choosing the TRT delivery method and dosing.

Basically, the heightened DHT boost from the transdermal may produce greater benefits at 35mg Q weekly than 70mg (actual) from injectable.

Genrally the 100mg of test cyp does produce higher serum T levels than 35mg of transdermal.

But this DHT is also a limiting factor when dosing the transdermal. I'm just not comfortable taking it as high as 10mg per day of transdermally delivered T usually takes guys. And I have recieved patients form online pharmacies who were being prescribed 20mg per day transdermal (200mg applied to the skin produces roughly 20mg to the bloodstream--and never even thought to check DHT or estrogen.

All in all, this is a decision which is made by the physician and the patient together.

Then you get folks like me with very little 5AR enzymes in the skin (I'm guessing based on my labs). I started with DHT at 12 on a scale of 155-553!!!! On 5g gel/day it went to 65. However, on cyp it has gone to around the 2/3 mark so apparently my skin doesn't like to conver T to DHT. Kinda strange.
