Ibuprofen Can Prevent Muscle Growth

Can this anti-inflammatory really stunt your muscle gainz?


Could you make DOUBLE the gains without taking any ibuprofen?! Maybe…

Let’s be honest here, we all go to the gym for one reason – to eventually make muscle gains. If you’re reading this thinking “I’m on a cut”, then at some point you’ll still want to pack on some lean mass, so this is still relevant to you.

Anyway, according to a recent study, if you’ve been ill and taken ibuprofen recently, then you might have stunted your muscle growth. Being srs bro.

We admit this sounds unreliable, so we’ll explain more about the study below.


In a clinical study carried out by M. Lilja et al,.[1] a group of mixed men and women were randomly given dosages of either ibuprofen (an anti-inflammatory drug), or acetylsalicylic acid (aspirin). They were then observed over an 8 week period, being asked to perform weighted knee extension exercises throughout.

Ultimately, it was shown that the participants who were given aspirin achieved bigger gains in muscle mass on their quads.

No ibuprofen bro

After seeing the results, a contributing doctor, Dr Lundgerg stated: “Our results suggest that young people who do weight training to increase their muscle mass should avoid regular high doses of anti-inflammatory drugs.”

Study Conclusion: The subjects that didn’t consume ibuprofen made almost double the gains in muscle mass than those taking this anti-inflammatory drug.

A write up of the study conducted by M. Lilja et al.

Summary: Ibuprofen can slow down muscle growth

If you’ve been taking ibuprofen to treat a swelling of some sort (hopefully not on your balls), then you can blame your lack of gains on this drug.

But now that you know, you can man the f*ck up and stop taking ibuprofen anyway. Thank us when your arms are over 20″ and you haven’t touched these anti-inflammatory drugs in years…
