I know this thread is old but I thought I’d share my experience with using Sustanon in case someone runs across this post using google, as I did. I took this under the supervisor of a doctor so I ran alot of labs while taking it. We started the dose at 25mg once a week and it made my total T level go through the roof, like over 2,000+, double the upper limit for men. I was training at the time and didn’t have any additional gains but I didn’t have any overt masculine side effects either.
The free T levels were within normal limits but with total levels that high, it’s definitely dangerous for long term use. Your body is capable of converting all that excess T into estrogen, and more estrogen is going to make your BMI go up. You’re probably better off using a compounded topical T if you want more gains with less side effects.
My most recent dose was 8.5mg taken 28 days before lab draw and that total T result was 38, within normal limits but it’s just barely enough to make my period lighter and reduce pms headaches, definitely NOT for training and gains. Hope that helps.
