Tough to say how you will respond to that dosage at that infrequency. Despite the literature that says Cyp’s half life is 12 days, its not its more like 6 days meaning after 14 days more than 80% of the Test you had injected into you last time will be gone.
It will also depend on how low or high your levels were/are prior to this HRT.
So many of use who are gear heads cyringe at the site of bi monthly HRT shots. You can keep the dosage the same but IMO 100mg every week is much better than 200mg every 2 weeks.
To address you question you should feel some tangible benefits of the Cyp by your third shot for sure if not perhaps even your second.
