You're way overthinking this.
The time to Cmax (max plasma concentration) of HGH is something like 6 hours if I recall correctly. Just take it when it's convenient.
First time ordering from CosmicPCT and overall happy with the experience. He was very helpful in my initial email with recommendations. I made payment 12/21 and received on 1/4 for India pharmacy. So 14 days total, which is reasonable given it's international and over the holidays. It spent 5...
None.
I use as much test as I can without an AI and then I make up the rest of my stack with DHT derivatives which do not aromatize. Plus a small amount of NPP (100-200mg) for joint support. Currently running 2,135mg of gear total, no AI needed.
This is your first cycle. Why start at a dosage 2-4x that of a TRT dose? Lower it to 200mg/wk and titrate up by 50mg as needed. You'll eventually find the max dosage you can tolerate without an AI, for most this would be 300-400mg. Throwing more drugs into the mix to deal with the side effects...
I've used Azteca, Colonial, Synergy Forge, GoodLyfe, and PharmaHGH.
I've never had any issues with any of them, although my favorites and the ones I've ordered the most from are the first two I mentioned.
