I think this approach is fine. I must say having been doing this for years, treating hundreds and thousands of men I have been underwhelmed with the results with topicals. Injections can cause peaks and valley and I have many younger men inject twice a week that smooths out the peaks and valleys. I think it is appropriate to follow the advice of your primary doctor and endocrinologist. I have just seen too many men spend months or years with gels with sub optimal results. Many men are diagnosed with depression and are not really depressed (I have no idea if this applies to you), but the presumed depression is base dupon low T.
My recommendation would be to pursue this but if a few months pass and results are modest consider another approach. Pellets are one approach to have smooth levels of T and are placed every 4 months.
First of all.. if you keep eating "1kg of sardines", you will get very sick. It's not a question of if you will get sick but when. Natural whole foods are great and you do not need supplements. As long as you are getting all vitamins and minerals and a surplus of calories, you're all good.
Secondly.. not even Big Ramy needs 240g of protein a day or he actually requires somewhere around that amount daily. The PROTEIN hype is all bullshit suggested by the "fitness" industry, that you need that much protein. It's a hustling moneymaking industry which takes advantage of idiots who will buy anything and believe everything.. You need 1- of protein pr kg body weight a day. Anything above that is fine but not necessary.
If you are not making gains, your training program is wrong or you are not doing the work required. If you are trying your hardest and not seeing results, my guess is, you are following a workout meant for someone on gear(drugs). Try a novice or medium 5x5 type program. Something simple with compound movements where you hit every body part in each workout. Do this for at least 5 months.
The nested term uses the same degrees of freedom as the treatment and interaction terms in the previous model. The design variables that are generated for the nested term are the same as those generated by the interaction term previously. But the nested term makes it more obvious that you are contrasting levels of treatment within each level of diagnosis. See the "Parameterization of PROC GLM Models" section in the PROC GLM documentation for some important details on how the design variables are created. As before, it is vital to know the order of the design variables that are created for an effect so that you properly order the contrast coefficients in the CONTRAST statement.
