This is purely my 2c, there’s always ten ways to skin a cat, but this is how I’d approach it within the scope of my knowledge
When you go back to cruising on TRT, use that phase to clean everything up. Dial in your bloodwork, get properly lean, and focus hard on maximising insulin sensitivity.
Monitor fasted blood glucose throughout the TRT phase and aim to keep it consistently in the 4.0–4.9 mmol range. Confirm this with bloodwork by checking HbA1c so you know where your true average is sitting.
Being as insulin sensitive as possible before you start pushing is critical. If insulin resistance is already elevated at the start, you’ll spend the whole push chasing your tail, forcing food, spilling over, then needing frequent mini-cuts just to regain sensitivity.
At the end of the day, insulin sensitivity largely determines whether the food you eat ends up as muscle or fat.
Once you’ve leaned out as much as you reasonably can in this phase, bloodwork is spot on, and insulin sensitivity is maximised naturally (no metformin or other drugs), you’ve created the longest, most productive runway for growth.
That’s your green light to push.
(Are you using GH?)
Test is your foundation. Push an initial increase as your first move. I don’t know your TRT dose, but as an example, adding 200 mg is a reasonable starting point.
Slowly increase calories and observe the growth rate. Don’t rush big jumps, overfeeding too early will blunt insulin sensitivity and cause unnecessary spillover.
Too much food before the body can utilise it is like smothering a campfire with wood before it’s hot enough to burn.
When growth slows, audit everything before touching doses:
Sleep adequate?
Stress under control?
Nutrition consistent?
Training volume and effort appropriate?
If not, fix those first.
If those are solid, ask the next questions:
Are you actually in a surplus and just gaining fat? If so, adjust.
Are you not in a surplus? Fix that first.
Is training performance still improving? If yes, there’s no need to increase anything yet.
Only if performance is stagnant and all health markers are still good would I consider increasing PEDs.
Primo is scarce right now, so I’d mainly use it as an E2-management tool, taking whatever additional anabolic benefit comes at the dose required to keep estrogen in a constructive range as test increases.
When progress slows again and your weekly test dose reaches a solid level your bloodwork and health comfortably allows with optimal e2 levels, NPP would be my next addition.
From there, repeat the same process.
Adjust slowly, monitor everything, and let bloodwork and health metrics be the jury on how high the total anabolic load is allowed to go.
Toward the end, if lifts begin to stall, you could add Anavar in short pulses e.g pre-workout, to help drive performance. That said, if all boxes are ticked along the way, you may not even need it.
The goal is to grow for as long as possible while staying healthy, which ultimately leads to better long-term muscle retention.
You don’t want to sprint toward quick growth and short-term gains at the expense of your health.
