Hello. This is my first post here, so bear with me.

​Background & Stats:
​Age / Height / Weight: 42 years old | 5'9" | ~200 lbs
​Body Fat: ~12% (conservative estimate)
​Lifting Experience: 25 years (background competing in bodybuilding and powerlifting)
​Current Status: Stopped competing years ago and transitioned to TRT.
​Injury: Badly torn L5-S1 disc.
​Training & Nutrition: Upper/Lower 2x/week. Track protein strictly (macros unmonitored). Training stimulus and nutrition are locked in based on years of competitive experience.

​TRT History & Response:
​Started TRT with Defy Medical for ~1 year, but never felt "dialed in."
​Went self-directed and experimented with test dosages ranging from 120 mg/week up to 500 mg/week, alongside varying pin frequencies and AI usage.
​Response to High Test: At 500 mg/week, I noticed minimal effects outside of an initial ~20 lb weight gain (primarily water retention).

​Individual Physiology & Side-Effect Tolerance:
​I seem to have a unique physiology that is highly resilient to changes in homeostasis:
​Estradiol (E2): Ranged from 15 to 90 pg/mL with virtually no noticeable difference in how I feel.
​Injection Frequency: Ranged from 2x/week to daily sub-Q with minimal subjective difference.
​Hematocrit (HCT): spiked initially during protocol changes, but has since stabilized.

​Current Protocol:
​Testosterone CYP: 98 mg/week (14 mg daily sub-Q)
​Nandrolone Decanoate (Deca): 125 mg/week (62.5 mg 2x/week IM)
​Notes: Titrated Deca from 50 mg/week over the past year. Noticeably helps my lower back/L5-S1 symptoms.
​Supportive: Tadalafil 5 mg daily
​Tolerance: No sexual dysfunction or classic negative sides on Deca
No AI

​Proposed Cycle Question:
​I wasn't a fan of high-dose Testosterone and prefer keeping my base low. I also don't want to run high-dose Deca due to its long half-life if unwanted sides pop up.
​I have been researching microdosing Trenbolone for the last year.
​Proposed Addition: Low-dose Trenbolone at 10 mg/day (70 mg/week) for 6–8 weeks on top of my current Test/Deca protocol.
​Past Ancillary Use: Anavar (decent results, but should have been leaner).

​Questions for the Forum:
​Given that standard advice strongly warns against running two 19-nors simultaneously (Deca + Tren), what are your thoughts on running this specific low-dose Tren protocol alongside my current 125 mg/week Deca?
​Has anyone with a similar high tolerance/resilience to exogenous compounds tried a low-dose 19-nor stack like this? If not what cycle is recommended for those experiencing similar?

​(Apologies for the long post, but wanted to provide complete context up front.)
