I'm currently fresh on the info needed since I have recently started a bridge from my 14 weeker just a while ago...
GHRP-2 is the most potent and most expensive, too. Here are some basic facts that will help you digest and brain storm your cycle layout:
GHRP-2 is the strongest but also has a stronger increase of cortisol release as the dosage increases. I would just recommend the saturation level, which is 1mcg/kg of mass. In your case, something close to 100mcg is considered the normal saturation point. It should be noted that increases in cortisol are within "normal" ranges so it probably will not matter especially if you use saturation dosage each time. GHRP-2 also may have a sleepiness factor w/ it.
GHRP-6 Also gives a strong GH release but has a less drastic fluctuation of cortisol increases as the dose increases. You'd have to take 400-600mcg at one time to receive abnormal cortisol and prolactin increases. This one is my personal favorite as it makes me really, really hungry almost instantly after administration. It's the best at holding mass from a previous cycle, imo.
Ipamorelin Pretty much just like GHRP-6 w/o the hunger inducing effect and absolutely no increases in other hormones like Cort and Prolactin. It's good too but harder to find.
Hexarelin Has the strongest pulse of GH but also has the strongest pulse of other hormones with it.
CJC-1295 Is a long half-life version of GHRH, which are not GHRP's. They act in different ways and should be considered supplementary to GHRP's. They add great effectiveness to a GHRP cycle. CJC-1295 only really needs to be taken 2-3 times per week max but at doses typically higher than the short acting versions like Sermorelin. If taken, use 250-500mcg, two to three times per week.
Sermorelin Aka GRF 1-29 or CJC-1295 no DAC is a GHRH just like CJC-1295 but with a half-life of 30 minutes. It must always be taken at the same time as GHRP for max effectiveness.
IGF-1 LR3 Is really only proven to be good at nutrient partitioning. No known studies of successful muscle proliferation exists with LR3. use it on a cutting cycle only, IMO.
My opinion - Is to use GHRP-6 w/ Sermorelin, 3 times a day @ 100mcg/injection of each hormone. Or ideally, you could take Ipamorelin in the morning (if you like to fast like myself), GHRP-6 during the day PWO, and GHRP-2 at night w/ Sermorelin alongside each dose.
Morning GHRP @ 100mcg, GHRH @ 100mcg
PWO GHRP @ 100mcg, GHRH @ 100mcg
Bedtime GHRP @ 100mcg, GHRH @ 100mcg
You'll need about 18-20g of each to get a good long cycle out of it (2 months or so)
