Deca and caber debate

Hi guys. Would just like to share my experience with deca and caber.


I'm in week 6 of a dbol, test e and deca cycle. (Cycle is on this forum)


At the end of week 3 I started 0.5 caber without knowing for sure if the deca was going to effect my prolactin.
Did 0.5 a week for two weeks and at week 5, I wasn't feeling like I was on test. (Low drive, erections only when the need arises, bit down on mood). I did bloods to be sure and estrogen was high within range and prolactin was low out of range.


Did some reading and low prolactin sides are just as bad. Low prolactin lowers test. And low prolactin allows estrogen to dominate and rise significantly. In doing so, it creates a mis balance of hormones.

The caber will should be out of my system in 14 days from the last dose. Will see how I feel then and update.


Bloods are very important during cycle also. Everybody is different and everybody's body will react in a different way once the foreign matter is injected. Only way to find out is to monitor with bloods and treat accordingly

Good that you're taking an analytical approach to this, but you can't really make the assumption that your low sex drive is due to low prolactin. That is highly unlikely. There are way too many variables involved. Deca itself is a progestin. It bonds to the progesterone receptor so worrying about a balance between prolactin/progestins and estrogen is not the issue. Your T:E ratio is more important. Maybe you need to up your test dose or use an AI. The dose of deca and test you are using could be a major factor.

Long ester Test (E/C) doesn't kick in properly for around 5 weeks anyway and being on deca makes one feel a bit low and less excited about life. It has a horrible effect on serotonin and dopamine.

If you get legit deca/tren dick, then cabaser works like a bomb. If your prolactin levels are high going into PCT, then your PCT will fail and be a waste of money. Cabaser is very effective for that. The combo of having elevated progestins from deca and elevated estrogen is one of the worst things for gyno sensitive guys.

So important: Have you done the same exercise without using Cabasser? If you are not prone to high Prolactin then you should stay away from prolactin drugs.

This is the cycle and I took a while to plan it and tried to get it as perfect as possible. This website was a major guideline to me.

Week 1-4 dbol 40mg ED
Week 1-12 450mg deca
Week 1-14 750mg test e
Week 15-16 100mg test prop EOD

Week 15-18 proviron ED
Week 3-18 500iu HCG weekly

Pct 3 to start 30 days after last test e pin.

Caber and arimidex on hand.

Took 0.5mg caber on last day of week 3 and 4. I never check prolactin, just took it cause I thought prevention is better than cure.
Imstarted to feel the sides and thought it was estrogen. I took arimidex and sides were still present. Knew something was up so decided to do bloods.

Results were:

E2 134pmol/L. Ref 40 - 161
Prolactin 1.5. Ref 2.6 - 18.1


Did some research on low prolactin and I have all the symptoms. It's much similar to estrogen sides so it's hard to tell without bloods.

I stopped the caber and will monitor myself and probably do a blood test again just to be sure.
Using 0.5mg arimidex EOD. Will continue with that till pct.

Hi MA

I posted my exact cycle.
I have honestly felt worse without steroids so I don't think the deca is effecting me on that sense. I felt like crap in the first week and it settled down nicely. Now when I look back issues only started after the caber.
Do you suggest holding on with cabber till sides appear?
Do you suggest testing prolactin again before the pct to make sure pct is not a waste?

Hi Pyro

This is only my second cycle and it is my first with deca.

I also agree with your statement. And the only way to find out is bloods around week 4 or 5 of deca to determine each individual's tolerance with deca and prolactin.

As with me. I suffered low prolactin sides by taking caber without knowing for sure and found out early on. Prior to starting caber and the cycle. I was more focused on high prolactin but didn't realize that low prolactin is just as bad if not worse.
