Thinking about Deca with TRT

Has anyone had negative side effects with adding deca to their TRT?
What Mg would you run it at?

I’m currently on 200mg of TRT and I’m thinking about adding deca. I can get 200mg/10ml vial of deca. I’m looking for something to add a little boost in the gym and help with my lower back and elbow pain. I’m a firefighter so my job is labor intensive and the joint relief is very alluring.
The biggest thing that worries me is the dick side effects. I wouldn’t say I’m prone to dick side effects but I tried Kratom for my back and joint pain and got ED.

Most use 200mg once weekly for 8-10 weeks. Off the top of my head, I’d say maybe 10% experience a negative effect, such as dyslipidemia, fluid retention, increased BP or ED. None have experienced any of those to the extent that are reported on the internet.

Seems to greatly increase estrogen when added to test (or stronger estrogen receptors, dont remember).

Might be good for low aromatisers.

Some get deca-dick, not sure why that happends. Some claim prolactin, others estrogen, some say its because of it replacing dht with some other shit.

Others love it and have zero problems what so ever.

what do you think about the idea that it is discussed so much on the internet that it becomes a self-fulfilling prophecy?

Nah dont believe that shit.

Im sure u can convince urself ur cock dont work to a point where u have difficulties getting hard from time to time.

But when your dick is literally 100% freaking dead, for months and months and nothing u do makes it come alive, theres something going on.

I know myself how much hormones impact ur libido and erection quality. Even slight unbalances in T, E and DHT can totally screw things up. Get it right and ure a walking raging sex crazed maniac hardon.

I put as much weight in that stuff as the usual: “libido is not only hormones … are you sleeping well? are you EATING YOUR CARROTS, BANANAS AND VITAMINES SIR??” that you will get whenever someone talks about test injections totally killing his cock all together.

… Just no, its the hormones, get it right and it doesnt matter ure underslept or havent gotten ur vitamine C for 2 weeks, u will get freaking hard and u want that punani.

So yeah, Im 99% sure nandrolone can screw things up that for some individuals make for deca-dick.

This seems to be unheard of for deca-only users (neither did I get get deca dick doing my deca-only experiment) - ask the old pros from the 80s and 90s who many of them used deca as base, and they will have zero idea what u are talking about, as deca by itself doesnt seem to create this at all.

However, deca, coupled with test … seem to screw things up totally, for some … and for others, nothing.

Those are my thoughts.

The Internet is the cause of deca dick for many. I don’t think it’s completely made up though. I think a few other explanations are out there too.

I’m guessing many get a very high sex drive while on it, and off of it comparatively is lower. Sex drive is related to ED. If you don’t feel like it, it doesn’t work as well.

I think another explanation is that Deca is one of the longer esters, and in addition 19 nors seem to be harder to recover from. I think guys cycling and coming off have a higher chance of not recovering testosterone production. They end up with low T, ED and a low sex drive.

Also, some guys not on any AAS develop ED or low sex drive all on their own. The amount of guys in their 30s with these issues is surprising (of course most men won’t tell you about these issues). Maybe that was soon to happen, and the Deca cycle didn’t do them any favors.

I do think deca dick can happen. I just think in many cases it’s something that’s not a direct cause from deca specifically.

I’ve actually heard the total opposite. I can’t find the article, I will look for it, but it states that Deca actually aromatizes at a rate of 1/5th what normal testosterone cypionate will. Have you heard contrary?

Oh yes, that is true, about 20%.

That is not what im saying.

What I am saying is: Deca “increase the estrogen receptors”, “strenghten the estrogen receptors” or whatever the hell you wanna call it

AND/OR

IN THE PRESENCE OF TESTOSTERONE, increase aromatization.

The actual mechanism behind this im not sure, but Im 93.4% confident that is how it works, as ive heard it plenty times and also read some study bout it.

Got it! Thank you for clarifying.

Don’t forget to get in your weekly tai chi. Boners and libido galore.

Do you know the mechanism behind decadck? I have been thinking about adding NPP to TRT for joints and for recovery. I have read a lot about DD being an issue on high dose Deca, but I cant find solid info on what the root cause is. You would think if its an E or Prolactin issue that could be easily countered by additional compounds or time… or both, to offset the imbalance

Deca does not convert to DHT:

Beyond testosterone cypionate: evidence behind the use of nandrolone in male health and wellness - PMC.

DHT plays a major role in erectile function:

Deca carries a greater affinity for binding to androgen receptors than test:

So deca “squeezes out” test and reduces necessary byproducts created by test as it converts and breaks down through the hormone cascade our bodies balance, including DHT - an erection potentiator. The selling point of low impact to scalp hair loss and body hair growth is also the dick problem.

As a rule of thumb, use deca at 50% or less of the strength of your concurrent testosterone injections. You’ll get the joint benefits without too much disruption otherwise, if any at all. Continue managing test sides as necessary.

Nobody actually knows the mechanism, it is only bro theories out there.

Some say its because of increase in prolactin (but it doesnt increase all the time, and sometimes people who get high prolactin still dont suffer).

Others claim its because DHN outcompetes DHT… eeeh maybe.

Some say its because deca increase sensitivity to e2, causing ed.

I never experience deca dick, i always get better function on deca.

Best boner ever was on npp only.

Its hugely individual, u need to try for yourself.

I just got off a 8 week run of Deca added to my TRT protocol. It was great for me, no ED issues, max lifts increased and recovery time got a bit shorter. I am going to go round again after a break.

Two things I did during the Deca cycle that I would recommend.

1: Up your AI dosage to a bit more than you have in just TRT.

2: Give blood halfway thorough the cycle.

Both were on recommendation of my TRT clinic, which is whom I got the deca through.

Did they do bloods before recommending increasing the AI and giving blood after 4 weeks?
To my very untrained eye both of these things seem unnecessary if not and if there were actual issues after only 4 weeks I’d be more inclined to decrease the dose or stop all together.
(Caveat, not a med pro).

Nandrolone very minimally converts to estradiol. Maybe if someone is a poor responder they need to do this, but doesn’t seem necessary to do out of the gate without E related symptoms appearing and/or labs to verify.

This needs to be burned into everyone’s brain with all this stuff. Start with low-ish dose and work up to find your limit. It’s wild how varied the response is between individuals for the same compound and dosage.

I have never given an AI with nandrolone. Studies that stated nandrolone “may” cause E2 type side effects (ED, etc.) were with patients/subjects not using testosterone concurrently.

Years ago, weightlifters would run nandrolone early ( first 4 weeks) in a cycle, both nandrolone and test mid cycle (for 2 weeks) , and discontinue nandrolone towards the end (last 4 weeks). I never heard of ED back then. We were pretty open regarding AAS effects.

Based on what I’ve seen, deca dick is not particularly rare, but not common, maybe one in twenty.

Regarding the four week blood test, that’s interesting. I would think you’d need a longer term for HDLs to drop, but I do not know. I like labs at the end of the “cycle” or at least prior to using it again. I know there are some practitioners that will recommend ongoing, indefinite, low dose nandrolone with TRT.

Yes to the bloodwork, was in response to both.

I use wraps quite often when lifting and I did notice a few weeks into Deca that I was more vascular, but the blood didn’t seem to be moving as much (hugely scientific analysis on my part!) what I mean by this is when I took the wrap off after a set, it took longer for the blood flow in the area to go back to normal, I might get some tingling ex:in my calves with knee wraps. I chalk that up to higher blood cell production from the Deca which thickens the blood, meaning giving blood is beneficial. My blood pressure rose a bit too but not alarmingly so. I like to give blood anyway as I’m O- (universal donor) so wasn’t a big deal to me, if the practitioner hadn’t recommended it I probably would’ve still done it
