Frequently Asked Questions (FAQs)

What is a good stack with Cardarine?

When considering a good stack with Cardarine, think about what this already brings to the table- endurance and fat loss.

A very popular choice is to stack Cardarine with Ligandrol (LGD-4033) for a combo of fat-burning and muscle-building.

This stack is known for huge gains in muscle mass while also developing a shredded look. Another option is to stack Cardarine with Stenabolic (SR9009), which is essentially a 2.0 version of Cardarine except it builds muscle.

These stacks are great choices for those in athletics, or bodybuilding.

Does Ostarine suppress testosterone?

Ostarine, one of the best SARMs known for muscle building, does suppress testosterone levels, but much less so than anabolic steroids.

It’s a mild SARM that selectively targets androgen receptors, which means it can cause some testosterone suppression, especially at higher doses or longer cycles.

However, the extent of suppression is still pretty low compared to other compounds. Use a PCT and your testosterone levels will be back in no time.

Do you need pct with Cardarine?

A post-cycle therapy (PCT) is used for restoring testosterone levels after a cycle of SARMs or steroids that suppress natural production.

Cardarine, however, does not touch the androgen receptors and has no known impact on testosterone levels. Therefore a PCT is not necessary after a Cardarine cycle.

How fast does Cardarine work?

Cardarine begins to show its benefits of improved endurance and fat burning within a few weeks of starting the cycle. Keep in mind that the speed of this often depends on how diligent you are with working out, along with your diet. Cardarine won’t work very well if you’re slonking beer and ice cream every night.
