Lean Bulk Stack 2026

Lean Bulk Stack - May until the end of October - ***2nd post because the 1st one got moved to another Thread topic***

172 cm - 43 years - currently at 89 kg - started with 81,7 kg on may 2026

This protocol is designed to combine strong anabolism (Test + Primo + Insulin + HGH) with good nutrient partitioning (Carb Cycling + Insulin + HGH) and active health management. This allows relatively lean gains while keeping classic problems (excess fat, poor blood values, declining insulin sensitivity) under better control.

a. Anabolic Foundation (Testosterone + Primobolan)​

• Testosterone provides the strong anabolic base (muscle growth, strength, recovery).
• Primobolan complements it very well: It improves the quality of the gains (harder, drier look), has relatively low side effects, and supports libido/well-being under testosterone.
• Together they form a classic, relatively “clean” stack with a good balance of results to side effects.

b. Nutrient Partitioning (HGH + Insulin + Carb Cycling)​

This is the real core of why the bulk stays relatively lean:

• HGH post-workout → hyperplasia, improves recovery, and enhances insulin sensitivity.
• Insulin (6 + 8 IU) → drives nutrients (especially the high amount of carbs) preferentially into muscle cells, particularly in the training window.
• Carb Cycling (High-Carb on training days + Strict Keto on rest days) → maximizes anabolism on training days while keeping insulin sensitivity and fat burning high on the other days.

These three work extremely well together: The carbs are directed into the muscles by insulin + HGH instead of being stored as fat.

c. Health & Risk Management​

• Pitavastatin + Ezetimibe → keep LDL extremely low (important under high androgens).
• Telmisartan → protects blood pressure and kidneys, with additional mild benefits for the heart.
• Jardiance (SGLT2) → slightly lowers blood sugar and has positive effects on the heart and kidneys.
• Nattokinase → supports blood flow and clotting properties (important with higher hematocrit).
• Peptides (MOTS-c, NAD+, GHK-Cu, Glutathione, SLU-PP-332) → support mitochondria, detoxification, skin, and recovery without heavily loading the stack.

Core principle: Flexible dosing based on blood values, subjective well-being, and progress. Current tested insulin protocol: 6 IU Pre + 8 IU Post on training days.

1. Hormone Stack (Flexible Dosing)​

HGH is injected as a single dose directly post-workout on training days. The testosterone dose will be flexibly adjusted based on blood values at the end of July (goal: stay at 750–800 mg if well tolerated).

Period	Testosterone Enanthate	Primobolan	HGH (Training Days)	HGH (Rest Days)
June 2026	600 mg/week	—	8–10 IU Single-Dose post-workout	4–5 IU evening
July 2026	750 mg/week	400 mg/week	8–10 IU Single-Dose post-workout	4–5 IU evening
Aug – Oct 2026	750–1000 mg/week (flexible)	500 mg/week	8–10 IU Single-Dose post-workout	4–5 IU evening

• Retatrutide: Used until KW 27 (2 mg/week), paused since 06.07.2026.
• Anavar: Optional in the last 4 weeks (October). Decision based on blood values mid-September.

2. Insulin Protocol (Liprolog) – Training Days​

Tested and current standard protocol: 6 IU Pre + 8 IU Post. Only on training days. No insulin on Strict Keto days.

Timing	Liprolog	When to inject	Combined with
Pre-Workout	6 IU	Directly after the Pre-Meal (Cookie)	—
Post-Workout	8 IU	15–20 min after the Post-Shake	HGH 8–10 IU

• Note on Jardiance: Jardiance (approx. 8 mg) slightly increases hypo risk. Especially monitor values 90–180 min after the post-injection.
• Possible adjustment: If blood sugar is regularly > 145–150 mg/dl 60–90 min after post-injection → increase Post to 8.5–9 IU. If it drops strongly (< 70 mg/dl) → reduce to 7–7.5 IU.

3. Nutrition & Macros (High-Carb Training Days)​

Month	kcal	Protein	Fat	Carbs	etc.
June	3,100	235 g	65 g	394 g	—
July	3,300	240 g	65 g	420 g	—
August	3,500	245 g	65 g	450 g	—
September	3,700	250 g	65 g	480 g	—
October	3,900	255 g	65 g	510 g

Strict Keto Days (3× per week): 2,350–2,650 kcal (Protein 220–230 g | Fat 130–145 g | Carbs < 25–30 g)

4. Pre / Intra / Post Workout Shakes + Timing​

Timing	Shake / Content	Insulin + HGH	Injection Timing
Pre-Workout	Lenny & Larry Cookie 113 g (~60 g Carbs)	6 IU Liprolog	Directly after eating
Intra-Workout	70 g Cyclic Dextrin + 15 g EAA + 8 g Citrulline + 10 g Creatine	—	During training
Post-Workout	100 g GEN Clean Mass + 5 g Psyllium + 15 g Collagen + 10 g L-Glutamine (~71 g Carbs)	8 IU Liprolog + 8–10 IU HGH	15–20 min after the shake
1 hour later	Normal meal (~150 g Carbs + 70 g Protein)	—	Covered by the post-insulin

Note: The post-injection (Liprolog + HGH) is deliberately done 15–20 minutes after the post-workout shake so that the carbohydrates are already in the system.

• Mid-September: Anavar decision (yes/no)

8. Skincare Routine​

Morning routine (Brightening + Red Light)

Hi Nightcome!

Got to say that planning and presentation are genuinely impressive. You’ve clearly thought through every phase instead of improvising week by week.

That said, there are several weak points (don’t meant to be rude, please don’t take me wrong):

GH does not improve insulin sensitivity, especially at 8–10 IU. It usually pushes it exactly the other way.

Insulin + Jardiance + strict keto days is a combination I would treat with extreme respect. It adds unnecessary variables and can create serious glucose and ketone problems.

Increasing insulin because glucose reads high after a huge shake is not automatically the right correction. More insulin is not always better nutrient partitioning.

Jumping between very high-carb days and strict keto three times weekly may hurt performance, digestion and consistency more than it helps.

The testosterone and HGH doses are already substantial. Adding Anavar and a long list of experimental peptides risks turning a good plan into noise.

Statins, ezetimibe, telmisartan and Jardiance can improve markers, but they should not be viewed as permission to keep increasing the anabolic load.

Excellent organization, but I’d simplify the execution.

A plan becomes truly advanced when every moving part is necessary, not simply available.

I agree with Donvitosharkone. High doses of GH work against insulin sensitivity, and taking a break from it on rest days would probably be a solid option here. Mechanistically... dropping GH for 1-1.5 day could allow you to leverage the benefits of accumulated IGF-1, which in the absence of high GH levels significantly improves insulin sensitivity and glucose homeostasis.

And yes, instead of an SGLT2 inhibitor, I’d probably lean toward berberine, especially on GH days... if only to avoid unpredictable issues with blood glucose and ketone levels when combining all these compounds with keto.

If alternating between High Carbs + Insulin on training days and Strict Keto on rest days doesn't cause the troubles Donvitosharkone mentioned, it could very well create that exact storage deficit that forces muscles to 'soak up' nutrients during the next feeding phase. Interesting, but... it needs to be simplified a bit.

Thx for the feedback! I really dont know why it translated the thing with HGH and improving insulin sensitivity... Wasnt meant that way! Sry about that. I let an AI translate the whole document from german to english.

Tried berberine, but i got so bloated with 500mg pre meal, it was really unpleasant so i stopped it.
Used the Sglt2 to improve eGFR rate, went up from 72 to 98 with 8 mg.

The keto days wont reach that high of a ketone levels because the high carbs days and strict keto days are like 2 days high, 1 low, 1 high, 1 low, 1 high, 1 low. Blood ketones never reach more than 0,5 right now. I also dont focus on ketons.
The stirct days really make me feel super good, clear mind, super focused and i dont feel that sore that long as when I ate more carbs on rest days like before.

So far not problems at all with digestion, performance and everything. it is the opposite, increasing weight, feeling great pumps and muscle connections, super fast recovery, awesome sleep.

But yes, I will adjust depending on health status and blood works. If there is no reasonable progress, I switch.

Thx
