does weight effect how much you should do in a shot?

[dreadnok89]

Just wondering, I'm thinking of switching to shots

no

while it may be a factor, it is insignificant. what will definitely matter more is the percentage of bodyfat, however. more bodyfat is associated with more aromatase activity.

this is all about population averages though; what matters to you is how you react.

[dreadnok89]

OK thx hrt. I'm about 260 but the only fatty areas really are my pubic area and some stomach. I guess normally areas?

[LowT Mike]

Yes...A few things here. Weight does play a part. But like HRT student said its more about your percentage of fat vs your actual weight. You will have more conversion of T to E the higher your boday fat is. The aromatase enzyme lives in adipose tissue so a heavy man will have more conversion and need to pay close attention to E2 levels. Ive treated men as high as 425 pounds. I couldnt get them on T right off the bat because even with an Anti E, Dim, Zinc, ect majority of there T would just convert. So a nice HCG diet. Shed 60-70 pounds get them below 350 then you can treat.

Another good starting formula that is weight dependant to start someone on T would be .9mg (of T)/kg body weight. Start low go slow when titrating dose.

[HRTstudent]

"start low, go slow"

lol I like it!


LowT Mike, on that formula (.9mg (of T)/kg), how many guys need that amount give-or-take 10%? I ask because it seems like some of the leaders in the TRT field are getting better results with T amounts under 100mg per week, sometimes even in the 60mg range.

i must be pretty dim, because my weight in kilograms is 91, so i did .9/91 and my result is in a decimal?

multiply, don't divide. 0.9 x 91 = 81.9mg.

[powerlifterty16]

that makes more sense but whyd he put the divide symbol lol?

[Trific]

that makes more sense but whyd he put the divide symbol lol?

To see if you could figure it out

[powerlifterty16]

what?

[phaedo]

... lol.

LowT Mike stated it correctly. He said 0.9mg (of T)/kg -- or verbally said as 0.9 milligrams of testosterone per kilogram of body-weight. Therefore, 0.9mg/kg * 91kg/1 = 81.9 mg.

It's hard to explain without a whiteboard, but your confusion stems from the units or "kilograms," specifically. The mathematical condition to express units and then to properly carrying them through the equation (even in this case with a simple a multiplication or division problem) is why LowT Mike expressed "/kg" (or "per kilograms").

Usually, you unknowingly reduce to the common denominator of units automatically. But the above equation shows your 91 kg is divided by one, illustrating the division of units (not numbers). It's like saying "1" or "1.0." Both the same number, just a different way to express it.

[dreadnok89]

OK I just did the math. 260 would equate to 105 mg of test a week. And I was reading the subq thread, it really is a no brainer to start shots

[kelkel]

... lol.

idk..ive always been taught that ''/'' means divide...even when spoken in terms of ''per''
either way i multiplied and got 80 something mgs. These numbers are for once a week right? I see many on here using 100-250mgs for their trt, and i as a 202 pound guy am supposed to be good with 81? That would be nice if true....i doubt im the smallest on this board in terms of weight lol.

[dreadnok89]

I wonder what ones numbers are at 250 a week

[ZenFitness]

Just back it out:

.9 * X = 250mg

250/.9 = 277.77 kgs = 612.4 lbs.

[powerlifterty16]

i still would be weary to start at less than 100 tbh lol.

[Black]

I think that formula would be a good place to start for someone new to TRT injections. Some people jump in head first and start too high (200+) IMO.

My clinic wanted me to start at 300mg which is ridiculous, so I dropped to 200mg. After doing more research and aromatizing more test, I started dropping my dose every 6 weeks and monitored how I feel. I've gone as low as 100mg a week and found out that 140mg is my spot.

This would be a formula for just a starting dose. When labs come back in 5-6 weeks the good doctor would then titrate accordingly. Sometimes down and sometimes up. Depends mostly on symptoms too. I train all my docs to treat the patient not the labs. Use the labs a basic guidelines but listen to your patient and there symptoms. Some are symptom free with a total T of 600 and free t of 20. Great your work here is done as the Practitioner. Other guys still present heavy symptoms and need to be pushed into the 900,1000,1200 range. I would say generally a mans sweet spot if I had a gun to my head and had to give you awswer would be 800s free of 20+

Think of it like this. If you went 60m/h (60 miles per hour) for 5 hours, did you go 300 miles or only 12???
