Looks like a good first cycle. Short and sweet.
Imo the threshold lower dosage amount for tren is 300mg, I would start there and work your way up pending sides.
Prami or caber, your choice. I prefer caber simply because I like pill form.
If you notice any loss in libido, up the test a bit. I think the way you have your cycle set up is the way everyone on tren should cycle. Test at maintenance dose to support sexual function and ward off lethargy, and let the tren do the building.
Dosing the test higher usually just results in more sides.
For pct I would stick with just clomid. Start at 100mg the first couple days and taper, your last week of pct should be around 25mg/day.
Hcg is not NECESSARY for this short cycle length but it would help.
If you're not willing to get some, run fadogia and DAA all cycle long.
For pin sites, Google spot injections.
Left glute, right glute, left quad, right quad, repeat.
