I have experience with the 1.62% gel, it works like testosterone suspension, possibly even faster imo. For me anyways.
Also, there is another difference with transdermal administration and that’s the fact that due to higher 5 Alpha reductase in skin, creates disproportionate DHT levels compared to the same total T when compared to injections.
So you get a different pharmacokinetic profile with gel. This could be useful for some, not for others.
In my experience running no test cycles and therefor having little to no DHT for prolonged periods of time/testing, even when using stronger pre workout androgens like SuperDrol, Anadrol and others, I actually found that when acutely adding back DHT via testosterone Gel, to actually more significantly increase the number of reps I was able to get. So in my experience bioidentical DHT might actually provide the strongest pre workout performance boost. However in my case that’s going from 0-60, as in, no DHT due to running no Testosterone, then adding a rapid acting form of Testosterone with disproportionately higher DHT conversion when absorbed through the skin.
I’d be curious to try pure DHT
But I didn’t notice anything else other than this pre workout performance effect.
