Using Injectable and Gel, Is It Ok?


Hello, i´m new to the forum currently on Test Cyp 125 mg a week, has anyone ever used topicals and injectable at the same time is there any type of counter effect to it, i com efrom using T gel 75 mg each day how ever my t levels were at the level i wanted them on, they came back at 6 ng/dl
I just got my second injection of test cyp and i was just wondering since test cyp releases over time and t gels is to apply each day is there a problem if using both ?? thanks
In my country (spain) we only have test cyp 250mg/2 cc and 100 mg/2cc
I have all my blood work done E2 levels are on point currently on Arimidex 0.25 mg twice a week and HCG 400 UI twice per week.


If you were not absorbing T gels, that can be a symptom of low thyroid function, read more below.

Injected T + T gel may increase E2 levels above injected TRT alone.

Please read the stickies found here: About the T Replacement Category

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.

I can be a bit abrupt in my replies and recommendations. I have a lot of ground to cover as this forum has become much more active in the last two years. I can’t follow threads that go deep over time. You need to respond to all of my points and requests as soon as possible before you fall off of my radar. The worse problems are guys who ignore issues re thyroid, body temperatures, history of iodized salt. Please do not piss people off saying that lab results are normal, we need lab number and ranges.

The value that you get out of this process and forum depends on your effort and performance. The bulk of your learning is reading/studying the suggested stickies.


Hello thanks, but Thiroid is just fine TSH, T3 and 4 checked as well as antibodies, any ways i was absorbing it just fine on the 5th day i got up to 8.5 ng of TT, but by 3rd month i was at 5.5 ng, i was feeling ok, i also know of this spiral effect in which at first test will go up but over time it decreases using gels/creams and that only 10% of the applied dose gets to the blood stream, i work in health care so i have “easy access” to get prescriptions for gels and injectable T with no problems, currently i´m doing 62.5 mg of T ciclopenthylpropionate i guess this is Cypionate, correct me if i´m wrong, is the only T we have in Spain besides of topicals
My only concern is to know if using topicals and injectables have some kind of counter effect with each other or not, thanks again.


What’s the point in doing both? Just switch to injectable and dial in your dose on that.



You’re overthinking this, use one or the other.
