Detailed Answer:
HI, thanks for using healthcare magic

A controlled substance or drug is one whose use is tightly controlled because of the risk of abuse.
Controlled substances are classified as schedule 1, schedule 2, schedule 3, schedule 4 and 5.

Estratest is classified as a schedule 3 controlled substance. This is likely because of the methyltestosterone component of estratest.
Estratest is a combination of two medications- methyltestosterone and estrogens.
Methytestosterone is a schedule 3 drug.

Schedule 3 means-these medications are less likely to be abused when compared to those that are schedule 1 or 2. If the medication is abused , the chance of addition is low to moderate. It has accepted medical use.
