Welcome to ology.
To answer your questions first.
Gyno is the development of female breast tissue in males. Gyno is the shortened version of gynecomastia.
Libido is the clinical term for sexual desire or drive.
Your diet needs to be exactly on point down to the gram. You need a plan for calorie count as well as macro-nutrient split.
Your daily H20 intake should exceed at least 1.5 gallons with 2 gallons being preferable.
Your training should be goal oriented and will vary on hypertrophic, strength or isometric movements.
You absolutely have to run testosterone with your tren. Prop is the most common to use with tren because of it's short ester. With out test you will experience tren dick. That is the best case scenario however. Testosterone is needed for a variety of uses in the body. Lack of testosterone can lead to numerous side effects.
That being said... Teutonic is right on point. Let me explain why.
Tren is the most potent anabolic steroid known at this point. It is usually NEVER RECOMMENDED until the user has multiple cycles under their belt including another milder 19 nor compond I.E. Deca.
Tren side effects include progesterone gynecomastia resulting from increased prolactin levels. Users with no prior experience with 19 Nor's bodies will have no idea regarding the effects of progesterone on their body. This progesterone gyno can be combated by the use of prolactin inhibitors. Example: Parmipexole.
Tren side effects include high blood pressure, dehydration, excessive sweating, hair loss, hard HPTA shutdown, night sweats, tren cough, increased liver enzyme values, tachycardia, depression, insomnia, and gynecomastia to name a few.
In the inexperienced (I.E. YOU) tren related sides can result in aneurysm leading to death due to increased blood pressure, loss of all gains due to lack of proper post cycle therapy (pct), tachycardia inducing a heart attack, and extreme cases of progesterone gynecomastia.
Bear in mind tren has an anabolic score of 500 versus testosterone's score of 100. Therefore all sides will be extreme compared to testosterone.
Also your use of a kit shows a complete ignorance of crystallography. Kit use will result in an unknown quantity of tren dosage. It could be underdosed in which case you have wasted your money or it could be overdosed and kill you. Due to your inexperience you are likely to use unsanitary methods of production leading to infection.
In my opinion if you do decide to use tren you have about a 80% chance of messing yourself up beyond repair. This is due to your lack of basic diet and training requirements, lack of basic cycling knowledge, lack of research regarding tren, lack of any cycle experience, low body weight, lack of Aromatase inhibitor (AI) and SERM knowledge, lack of proper post cycle therapy (pct) protocol knowledge and your lack of proper dosage measurements via use of a kit.
If you truly desire to use anabolic steroids the first cycle should be 500mg test E a week for 12 weeks.
However I think you should post your diet and training so we can make a determination if improvements can be made without gear or if gear is necessary.
I hope you take this advice to heart. It is not a scare tactic when we say tren can kill you.
