If this is the case, then how should I know whether to keep my same dose or increase it?
You cant.
The question is: how old are you and whats your goal?
If your goal is anti aging, life imorovement and moderate anabolic and fatloss effect i woukd advise you to go with peptides. People say peptides arent effective, well tell.that to my swolen hands. People think that peptides arent effective because they dont know hoe to take them.
My protocoll right now (which i had to stop for a couple of days because i couldnt make a fist anymore and got bad carpel tunnel syndrom from the igf-1 an GH elevation):
-Morning before fasted cardio: 100mcg GHRP-2 + 100mcg CJC no DAC
(100mcg or 1mcg/kg bodyweight is considered tge saturation dosage)
After weight training: 100mcg GHRP-2 + 100mcg CJC no DAC
Right before bed: 2mg Tesamorelin + 500-600mcg Ipamorelin
I want to say that Tesamorelin with Ipamorelin is the real deal and absolutely the main driver here.
So if sou can afford it, it woukd be best to switch the morning dose with another 2mg Tesamorelin + 500-600mcg Ipamorelin but its not necessary believe me thos proticoll right now is already vers potent. On the other hand: if you dont mind spending 160€ per Month why not. Right now im pretty broke so yeah.
Some things to add:
When i say "take it right before bed" i dont mean you take it, go get a glass of water, take a piss ans rub one out before switching off tge lights. I mean, its the last thing you do before trying to fall asleep. The closer to your sleep the better.
Some things you could add to it
-Arginie silcate/AAKG and Citrulline. Arginine is a Somastatin inhibitor. I dont use it before bed because i used it as a pump booster and i have the feeling that im building up a tolerance so i want to save it for my workouts.
But if you dont use it, its a cheap way to further boost your peptides. Just take a big dose (i take 12g arhinine and 12g citrulline because its so damm cheap so yeah) 20min before you peptides (timing is imprtant though, shouldnt be to earyl nor to kate obviously)
Other things to boost your peptides:
-melantonin (again Soma supressor) which i take anyways for sleep
-GABA (however tge action isnt quiet clear)
Whats the other option? Welm you want real big anabolism.
Then i would adivise to take a real dosage of GH. Starting at 6IU. If you are young (in your 20s) i wouldnt go lower i would rather go higher.
With 8IU you can be sure, you will get significant anabolism.
But with 4 IU at a young age its not worth it. You may risk even lowering anabolism or even if you wont, you wont get a lot more from it. Then peptides is the better choice.
HOWEVER! This doesnt mean that there arent people (lets say 32 years old) that will get significant resukte from even 2 IU. Thats the thing, it depends on the individual.
