This is what I primarily use from Robolics for Blasts aswell as cruising. Keeps more stable bloods than regular Sust keeps in my opinion instead of having such a huge roller coaster effect with numerous shorter acting esters
Blood levels can be stable on any test. That's more for like trt similar to sustanon with a once a week dose to keep you stable as esters fall off. For cycling I'd just stick with a single ester myself and twice a week pinning
