I have a solid amount of experience with Triptorelin
What I will say is this. Alot of people years back were under the impression that Triptorelin was all you needed for PCT. So they would do a shot or two and then that was it and assumed it would return their HTPA.
Now what I saw in patients and clients was that for several months indeed, the clients or patients labs would show a baseline or a returned HPTA. But then the crazy thing that happened in every patient that didn't use Clomid alongside it during PCT, was that they all crashed eventually. To a zero basically.
So we saw what I would call a false positive. It would appear the person had returned to natural test production and then suddenly their labs would show they were hypogonadal, aka the result was only temporary.
Is it suppressive? Does it have a super long bioavailability that keeps the users T levels spiked for even a few months?
These are all questions I have and I have never seen a study to prove why. There are people who swear Triptorelin is the end all and be all of PCT to this day, and they have no clue that months later they are gonna crash and burn.
So I am unsure if you should use it.
The tried and true method is Clomid. And of course Nolva alongside it works well. That is the old school 1990s edition that has always steadily worked.
All the other tricks along the way have failed. And to this day people think you can run HCG for a few months and be "recovered". LOL. They have no clue that HCG is actually used as HRT and spikes T levels and so the numbers you are seeing are not that you are recovered but rather that you are boosted up and the second you get off the HCG, you are gonna crash and burn and be hypogonadal.
Jumpstarting with a week or two of HCG is cool and then running your Clomid 3+ months.
In the Endo field I saw that a patients HPTA took anywhere from 2-12 months to return. This is not an opinion based statement.
