General Questions

What is Estrapen and what do you offer?

We make insulin pen vials, filled in a safe manner with Estradiol Enanthate. We also sell pens, that we include in our kits.

What is in your Estradiol?

Our vials are made with MCT oil, Benzyl Benzoate, Benzyl Alcohol and Estadiol Enanthate raws. We are in the process of testing Miglyol 840 instead of MCT Oil, but we are still making sure its safe to use before putting it up for sale.

Is my information secure when I place an order?

We take data security very seriously. Your data is autoremoved after 7 days, after contacting the bot. We only use the data to create a shipping label, then immediately delete it. Due to Signal's strict data security policy, we can guarantee that no one can see your personal info aside from us, and the shipping company.

Can I use other homebrewers estradiol to refill my vials?

Technically, yes, but we do not recommend you do so. As of Jan. 27 2026, our Estradiol is no different to the EEn offered by other homebrewers. However, when refilling vials, you have to understand the risk. We work in a safe and as close to sterile as possible environment, we make sure your vials are perfect. Most of the time, you will not be able to do that at home, therefore you risk dust, bacteria and other contaminants ruining your vial, and potentially putting you at risk. If you refill your vial, we cannot guarantee that it will be safe to use, which is why we cannot recommend doing it. In addition, once we switch to Miglyol 840 from MCT oil, the viscosity difference will be noticable, and the MCT oil might feel less comfortable and painful to use than the mig.

Ordering & Payment

How much are the kits?

The pen + 3 vials kit is 75 euro, the 3 vials are 60 euro.

Can I modify or cancel my order after placing it?

You can, for up to 2h after placing your order. Contact us to modify or cancel your order.

Do you accept anything other than crypto?

Sadly not, any other payment methods are too risky for us to use.

Will I receive an order confirmation?

Yes, however they usually take a while sadly due to us not being able to easily implement a auto confirmation sender on Signal, so we have to send them out by hand.
