Is nasal spray the only possible fast acting testosterone option? If so, why?

I am currently only Test C and HCG injections, but I was thinking of possibly moving to the empower nasal spray to save money, but also to maintain natural testicular function. However, I’m a bit concerned about putting gel in my nasal cavity 2x daily for any period of time over a month. I saw some other posters here had the same concern with using the product.

However, I was just curious, since it seems this is the only exogenous Testosterone product which doesn’t suppress the HTPA, is there a reason other mediums of testosterone can’t have the same effect?

E.g. Why don’t/can’t any gels, pills or injections use esters that don’t have long half lives to mimic the same fast acting nature of nasal spray to maintain LH/FSH?

Is this some physical limitation? Or does something like this already exist and I am mistaken?

For sufficiently fast action, testosterone nasal gel in the form of Natesto is the only medium that has solid research behind it. However, it's possible that other forms of testosterone behave similarly. The most promising alternative is buccal troches.The pharmacokinetics appear to be similar to those of Natesto. You might think that injections of ester-less testosterone would be candidates. However, testosterone suspensions are not considered promising, as there's research suggesting that the suspended testosterone crystals dissolve relatively slowly. Testosterone in oil is another possibility, but I've not seen any research on this form. Best guess is that absorption is still a little too slow.

Maximus offers a related option: One takes oral testosterone along with enclomiphene. The oral testosterone is suppressive of the HPTA, but Maximus has demonstrated that this is readily counteracted by the enclomiphene.

Appreciate the info, hopefully we see more research in this area soon. I think a lot of the hesitation from current physicians is the fertility risk for their patients.

Unfortunately Enclomiphene was the first option I used and I ended up with pretty bad eye floaters. I think that’s just the risk with SERMs in general since it’s hard to control where they will and won’t bind as I understand it.
