Intro Thread — TRT + GH + Primo/Tbol | 49 y/o | 5'11", 180 lbs @ 20.4% BF | Mid-Cycle Clean Labs

[bastxpl]

Hey Mezo —

First-time poster but long-time reader. I'm 49, 5'11", currently 180 lbs, and body fat is at 20.4% (Navy method) as I work through a focused summer cut. I've been on TRT for just over a year, under endocrinologist care, and have experimented with peptides and low-dose GH mainly for fat loss and recovery. This is my first structured stack — designed to shred fat while maintaining strength, function, and bloodwork stability.

Goals:

Drop to sub-12% BF

Preserve lean mass and CNS drive

Keep metabolic and cardiovascular labs in check

Understand how my system handles this compound combo



Current Stack (Week 2 of ~10–12 Week Cut):

Test Cypionate: 100 mg/week (TRT base)

Primobolan: 300 mg/week (split 2x)

Turinabol: 40 mg/day (20 mg AM, 20 mg PM)

HGH: 2 IU/day, AM fasted (subQ)

Anastrozole: 0.25 mg every 3 days

Mounjaro (Tirzepatide): Rx from TRT doctor for metabolic synergy

Supps: NAC, TUDCA, magnesium glycinate, CoQ10, creatine, collagen, spermidine

Lifestyle: Mediterranean/keto-hybrid diet, ~180g protein/day, alcohol-free, tapering nicotine, 7–8 hrs sleep, 3–5 rucks/week + calisthenics

Recent Labs (Week 2 of Cycle):

Hormonal:

Total Testosterone: 2190 ng/dL

Estradiol (sensitive): 49.7 pg/mL

SHBG: 38.9 nmol/L

Prolactin: 324 mIU/L

IGF-1: 707 ng/mL

TSH: 1.54 | Free T3: 4.91 | Free T4: 18.2

HbA1c: 5.4%


Lipids:

LDL-C: 68 | HDL-C: 49 | Triglycerides: 66 | Total Cholesterol: 130

Non-HDL: 81


Liver/Renal/Inflammation:

AST / ALT: 24 / 24

GGT: 19

Creatinine: 96 | eGFR: 76

CRP (hs): 3.57

Ferritin: 129

Homocysteine: 11.6


Hematology:

Hematocrit: 51% | Hgb: 18.4 | RBC: 6.15

WBC: 14.4 (slightly high — likely training/inflammation?)

Expectations:

This cycle is short and purpose-driven. I’ll reassess after 10–12 weeks depending on body comp, labs, and energy. Using this as both a cut and a systems test — not just chasing aesthetics but dialing in total readiness.


Looking For Feedback On:

Primo + Tbol synergy: how’s the pairing?

AI strategy: E2 at ~50 pg/mL — ride it or nudge down?

GH timing: Is AM-only solid or worth adjusting?

Anything in my bloods worth adjusting now vs. post-cycle?


Appreciate any insight from vets here — especially those optimizing cycles for performance without wrecking internal health.

Im no expert but we are somewhat similar age and weight. 200lb in my case at 20% using various methods and taking average.

So... thats a lot going on but just looking at the products, 100mg T + 300mg Primo, and AI every 3 days? Im just guessing, but wont 300mg Primo vs 100mg T going to crash your E2? Have you tried Primo before to see what it does to you?

The general recommendation I see for Primo is 1/2 the amount of T to maintain E2. So with 100mg T, the general consensus seems to be 50mg Primo. Again you need to verify. I dont know what TBol will do so you will need to look that up as well but I assume it doesnt aromatize either.

I dont know about you, but when my E2 is low, my knees hurt during workout and get achy for days after workout. They are perfect when my E2 is 40-50.

Even at 20% bf that’s way too much e2 suppression. Drop the AI and drop primo
To 50. Or drop AI and raise test to 400
