Planning another Test + Deca Cycle after several years - looking for advice and experiences

[TheF30Guy]

Hey everyone,
I’m considering running another Test + Deca cycle at 2:1 ratio (400 Test 200 Deca) It has been quite a few years since I last used Deca.

This would be my 5th cycle overall. My most recent cycle was Testosterone + NPP, and while the results were good, I struggled with high blood pressure, so I ended the Cycle early after 8 weeks, and this time I’m trying to do as much research as possible before making any decisions.
I’m not looking for someone to design a cycle for me. I’d mainly like to hear from people with first-hand experience.

Some things I’m interested in:
•What did your Test + Deca cycle look like?
•What did you find to be the sweet spot in terms of balancing results and side effects?
•How did Deca compare to NPP for you?
•What side effects did you experience (blood pressure, water retention, prolactin, libido, etc.)?
•What blood work did you monitor, and how often?
•What health support or supplements did you use?

Looking back, is there anything you would have done differently?
Any general tips for someone returning to Deca after a long break?

I already plan to monitor my blood pressure closely and get regular blood work. I’m just trying to learn from people who have actually run this combination and hear what worked well—and what didn’t.

I'm currently completely off of any AAS.

Thanks in advance for any advice or experiences you can share.

Hey bro…

Good question, and I respect the fact that you stopped the NPP cycle early when blood pressure became an issue. That already tells me you’re thinking like someone who wants to stay in the game long term, not just chase a few fast kilos.

My HONEST take: if NPP pushed your blood pressure up, Deca deserves even more respect. NPP clears faster, so if things go wrong you can adjust quickly. Deca is slower, heavier, and once side effects build up, you can be dealing with them for weeks. That doesn’t mean Deca is “bad,” but it means you need to enter it with much more patience.

For me, the key with Test + Deca is not the ratio on paper. It’s whether your blood pressure, hematocrit, estrogen, prolactin, sleep, digestion and resting heart rate stay controlled. A 2:1 ratio can work well for some, but it doesn’t magically prevent issues. Water retention, increased cardiac load, higher BP, libido changes and mood changes can still happen.

Before touching it again, I’d want a clean baseline: CBC, hematocrit/hemoglobin, lipids, kidney/liver markers, fasting glucose/HbA1c, estradiol, prolactin, total/free test, SHBG, blood pressure average over 7-10 days, and ideally an ECG or echo if BP was a real problem last time. Then repeat bloodwork around week 5-6, not only at the end.

Health support is basic but non-negotiable: daily BP tracking, cardio, controlled sodium/potassium balance, omega-3, enough water, no dirty bulk, and don’t let bodyweight jump too fast. With Deca, fast scale weight is often water and pressure, not quality tissue.

If I were returning to Deca after years away, I’d treat the first part as a tolerance test, not a “growth at all costs” phase. Keep food clean, keep the surplus modest, don’t add extra compounds, and don’t wait until side effects are obvious before reacting.

The BIG lesson: Deca rewards calm, structured people and punishes impatience. If your BP starts climbing again, the answer isn’t more ancillaries first. The answer is usually less load, less water retention, better conditioning, or ending the run.

Run the health markers, not the ego. That’s how you get results and still have a body worth building in 10 years.

Thank you for your detailed answer brother. Of course first of all I'm gonna do my bloodwork to check my overall health before hopping on again. To be honest, Deca/NPP seems like too harsh of a drug for me, I think it would be best to just use Test and Primo again since that was a very mild cycle for me. After all, you're right and I don't want to damage my body longterm. Do you have any experience with Primo? Also, have you heard about or even used Retatruide?

Hey bro!

That’s exactly the kind of conclusion I was hoping you’d reach.

If NPP already pushed your blood pressure up, then choosing Test + Primo instead of going back to Deca is not “playing it safe out of fear.” It’s simply making the smarter decision based on your own data. The best compound is not the one that looks strongest on paper, it’s the one you can run while keeping your blood pressure, sleep, bloodwork and head stable.

Primo is one of those compounds I respect a lot when used properly. It’s not dramatic, it doesn’t blow you up overnight, and it won’t give that wet Deca look, but that’s exactly why many experienced guys like it. It usually gives cleaner tissue, better look, less water retention, and a much more manageable overall profile compared with nandrolones. The main things I’d watch are estrogen going too low if Primo is too high compared to Test, HDL dropping, hair if you’re prone, and making sure the dose is high enough to actually justify using it.

For someone like you, who already knows BP can become the limiting factor, Test + Primo makes much more sense than Test + Deca. You may gain a little slower, but you’ll probably keep more of it, feel better during the process, and won’t spend the whole cycle trying to “control damage.”

About Retatrutide: yes, I think it can be a very useful tool, especially if appetite, body fat, insulin sensitivity or staying lean during a growth phase are issues. But I wouldn’t treat it as a magic fat-loss drug. Its real value is helping you control food, improve adherence, and avoid getting sloppy. If you’re already lean and eating well, you don’t need to push the dose high.

My final take: get your baseline bloodwork first, choose the cycle your body can actually tolerate, not the one your ego wants, and don’t underestimate the value of a clean, boring, productive run.

Test + Primo, modest surplus, cardio, BP tracking, repeat labs mid-cycle. That’s how you build without paying for it later.
