Is it okay to change ester in the middle of the cycle

Hello everyone,

First of all, thank you for taking the time to read this and helping me with my situation.

So right now I’m taking 200 MG of cypionate twice a week . It’s been one month and I’m on a three month cycle. Now I am planning to take 400 MG once a week which contains 200 MG of cypionate and 200 MG of decanoate. Is this safe to do if so when can I start the 400 MG cycle? My last dose of 200 MG was four days ago

Again, thank you so much for helping me out

So if i’m understandin gyour going from 200mg of test alone to 200mg test and 200mg deca(nandrolone) or test deconate? The testC/testD mix would be weird as I have never seen that before.
You need to clarify what your intending to take.

Thank you for your response. So I am taking total of400 MG of test C but splitting it twice a week. But now instead of pinning twice a week, I’m planning to take 400 MG of test C + test D (200 mg each) once a week

Don’t take the Test D. Test is cheap, stick with C or buy more C.

If it’s 400mg/ml then steer clear. It’s a high concentration and it will hurt like hell.
Just do two shots per week. Steadier levels.

I have switched mid cycle between test c and test e with no problems. I didnt mix in one pin and used alternate hips

I have switched mid cycle from 750 test per week to 500 test/600 deca (with a week in between of 500 test alone for the transition not to become overwhelming.

But mixing two esthers in a single syringe is a good way to find out if you can get an injection reaction and I really dont see the point

In the mid 1970’s Organon developed a multi ester testosterone called Sustanon. It was a combination of 4 esters

The four esters in the standard Sustanon 250 formulation are:

  • Testosterone propionate (30 mg) - A fast-acting ester that releases quickly into the bloodstream.
  • Testosterone phenylpropionate (60 mg) - A slightly slower, medium-acting ester.
  • Testosterone isocaproate (60 mg) - Another medium-acting ester that helps maintain levels for a longer period.
  • Testosterone decanoate (100 mg) - A long-acting ester that provides sustained release over an extended duration, up to several weeks

Blending esters of testosterone is nothing new.

E and C are interchangeable with similar half life’s, E being slightly shorter. D is too long and can mess up your PCT if you’re not on TrT. I wouldn’t run it and also would steer away from high concentrations as @s.gentz stated. Typically 250mg/ml is as high as I would go.

Actually it comes blended 200test c/200 test D

Thank you everyone for the information you guys provided.i will stick with test c 200 mg twice a week

Yes I understood that thanks.

Thank you. I also wanted to ask . For my PCT I am using HCG and then clomid

HCG two days after my last shot for 2 weeks one day on one day off and then starting clomid for 4 weeks /25 mg

In your opinion is this okay?

Thank you

I don’t see any issues with that. Do you plan on pulling labs after PCT?

Yes..how long I need to wait after PCT for bloodwork?

Couple weeks should suffice

Do we still run PCT? If this is still a thing would HCG (at 500iu to 1000iu) pw not be better off throughout the cycle and into PCT?

If you’re not on TRT then yes you would need to PCT. You may run HCG the whole cycle or just the bridge between your last shot and PCT start. You do NOT run it during your PCT
