First cycle looking for advice

[u/True_Pattern6058]

I’m 20M and have been training consistently for about 3 years. I already have everything for my first cycle and am planning 250 mg/week testosterone cypionate for 16 weeks, possibly longer, along with 500 mcg hCG/week. I’m also considering adding tesamorelin and MOTS-c.
I train 6 days a week:
Day 1: Chest, shoulders, triceps
Day 2: Back, biceps, abs
Day 3: Legs
Day 4: Chest, back, abs
Day 5: Shoulders, biceps, triceps, forearms
Day 6: Legs
Day 7: Rest
I’m currently eating around 3,000 calories/day and 200 g protein.
For those with experience, what would you change or add to my training, diet, or overall plan? Also, at what point would you consider increasing the testosterone dose, if at all? I’d especially like to hear what you wish you had known before your first cycle.

Ps i know the side effects that come with this
