Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia . 
This was my very first cycle. I kept it simple although I did add an oral and wish I didn’t. I did 500mg of test Enanthate Tuesday/Thursday for a 12 weeks cycle. For AI I did arimidex .25 MWF. The last 6 weeks of the cycle I introduced winstrol at 20mg per day dosed 10mg morning, 10 mg before bed. I then increased to 20mg/40mg after 4 weeks. I then took hcg the last 2 weeks of the cycle, and two weeks after last test injection, then began pct of clomid/nolva for a duration of 4 weeks. During this time I did blood work several times before the cycle, during, and now post cycle. So the products to the best of my knowledge were legit as my weight increased, strength increased, acne increased, and blood work showed nearly a 4xs increase in my testosterone levels as did my estrogen b4 introducing Arimidex to bring it back down to normal levels.
Side effects of testosterone enanthate include symptoms of masculinization like acne , increased hair growth , voice changes , and increased sexual desire .  The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).   It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy .  Testosterone enanthate is a testosterone ester and a long-lasting prodrug of testosterone in the body.    Because of this, it is considered to be a natural and bioidentical form of testosterone.
