Muscle Gain with Laxogenin Capsules

Laxogenin is a plant based supplement which is isolated from the smilax sieboldii plant, a species common to China and Japan.

First isolated in 1992 it is considered a Steroidal Sapogenin similar to Tribulus, however it is proven to be much more effective.

The active ingredients Brassinosteroids are said to be responsible for the muscle building and strength properties, having a positive effect on lean muscle growth.

Bulk Nutrients' Laxogenin is blended with 25mg Phosphatidylcholine to enhance absorption, with each capsule containing 25mg of Laxogenin.

Frequently asked questions about Laxogenin

What is Laxogenin?

Laxogenin is a sapogenin, a natural anabolic agent which is derived from the plant smilax siboldii. It is said to have similar effects to anabolic compounds, however, Laxogenin is natural and is not liver toxic.

It is primarily taken to improve strength and increase muscle volume, as well as to increase recovery after training.

What is a typical dose of Laxogenin?

A standard dose is approximately 50mg of Laxogenin, which is 2 x 25mg capsules of the Bulk Nutrients product. Some people use lower doses, while others prefer higher doses. Dosing around 200mg has been reported to cause headaches, which is why doses around 50mg are recommended.

What kind of real world benefits can I expect from Laxogenin?

Recovery from injury may well be faster. Strength will be improved, in a similar way to using a product such as creatine.

Which people should / shouldn’t use Laxogenin?

Competitive “natural” athletes should be great responders to Laxogenin.

Athletes who are suffering from injury could use Laxogenin during the recovery process.

While still useful for women, men seem to respond better to Laxogenin due to the effects of test levels on brassinosteroids. Higher test levels seem to further enhance its benefits. This is backed up by some women being virtually “non responders”.

Is Laxogenin ok for drug tested / natural athletes?

Laxogenin is not on any SIA - Sports Integrity Australia/WADA prohibited substance lists as of August 2018. Laxogenin does not raise test levels so it is very unlikely it could trigger a failed test due to hormonal level changes.

What about absorption, is this a problem with Laxogenin?

Laxogenin appears to have some issues with absorption, which can be countered one of two ways. The first is by transdermal absorption (applying it to the skin as a lotion) the other when combined with another compound, such as phosphatidylcholine which can assist absorption.

At Bulk Nutrients, we have included phosphatidylcholine at 100mg per capsule alongside 25mg of Laxogenin to increase absorption.

What time of the day should I use Laxogenin?

There is no right or wrong time of the day to take Laxogenin, the most important thing is using it daily, so don’t skip doses. If doses are missed, we do not recommend extra is consumed.

Can I take Laxogenin with other supplements?

Laxogenin is fine to use with other supplements such as creatine, glutamine, protein etc. It is logical that Laxogenin would be even more effective when combined with products such as test boosters, as anecdotal reports suggest effects seem to be greater when test levels are higher (hence why men are better responders).

Does Laxogenin require cycling?

Studies on rats using 28-Homobrassinolide showed that no androgenic side effects were recorded, and that hormonal levels are not affected. Anecdotal reports of Laxogenin suggest that many people find optimum benefits when cycles between 8 – 10 weeks are run. An “off” period of 4 – 6 weeks would then follow.

How do I know that Bulk Nutrients' Laxogenin is real?

Laxogenin is an extremely expensive compound, one that we pay a lot of money for. We purchase Laxogenin from our very trusted supplier (who we have dealt with for over 5 years and supplies us with millions of dollars’ worth of stock each year), we only receive the Laxogenin after approving the laboratory reports on its purity.

Bulk Nutrients regularly tests its own compounds for purity in Australia through HPLC testing, with our ingredients having an impeccable record. We 100% guarantee the purity and potency of our Laxogenin.

Is the packaging Laxogenin product recyclable?

Yes! The capsule container and lid can be recycled as hard plastics in your local council pickup.

If you'd like more information, check this article which breaks down how all of Bulk's product packaging can be recycled.

Can I receive a discount buying more than one bottle of Laxogenin at once?

Absolutely! Price breaks for Laxogenin begin when you purchase 4 bottles. Just add 4 bottles or more to your cart to see the savings.

Are Laxogenin Capsules Vegetarian/Vegan Friendly?

Yes they are! We use plant based capsules. This means our Laxogenin Capsules are 100% vegetarian and vegan friendly.
