Yeah, at 15, you have sm natty production already, just enhance it, id do right before bed to keep it simple, but if you really have alot of it to spend, large bolus at night max 200mcg of each and anover 100/100 dose in the morning before breakfast.
Can put your IGF to the upper range, and will give ya better sleep.
Expect an extra inch out of this total, if you use it for entire puberty, FYI, HGH + AI gives you an inch a year.
also, the question was how long to run the "cycle" ? Just as long as you have CJC and Ipa?
Look, honestly would reccomend gigadosing MK 677 as that actually HAS clinical trials, and they went above and beyond at near 100+ mg per day, and achieved similar, yet slightly inferior to HGH+ AI results, about 0.8cm less give or take.
MK 677 has been PROVEN to put your IGF up, and many people HAVE used it in the past, Kent bought the raw powder and dosed 80mg a day, little did he know, very similar to the clinical trials.
So, yes, not all secretogogues are complete cope.
Do it NOW, time is of the essence, how much ya got?
