The ester is cleaved from the hormone before it even reaches the blood stream. Using a hormone with an ester (in a topical) is only going to hurt absorption. Even with a base hormone, there is still a 12-18 hr timed release effect depending on your topical carrier.
Besides, the max flux seen an hour after application mimics a more natural release of hormones. Ie, a burst of testosterone in the morning similar to the bodies natural rhythm. Plus, transdermaly applied base hormones clear the system within days, making for a very quick rebound.
The only pitfall with transdermal testosterone base is excessive aromatization & 5-alpha reduction as it passes the skin. This is why I would opt for nandrolone base in a topical.
Eitherway, topical test base is cheap, powerful, and painless… not to mention very fast acting.
