Anything in the OTC supplement that speaks directly to increasing Testosterone, would be a waste while on Clomid. Aphrodesia is another thing all together - there are scientifically proven plants that make people horny (why you aren't horny from just the Clomid High T and resulting conversion to DHT is another question). Any other "feel good", "well being" stuff in there may help as well. A company won't tell you it's ok to take with an Rx drug - they'll say ask your Doc for liability reasons (probably) - but I'd take it alongside, no worry.
Interesting that your doc has you on a SERM alongside TRT - not common.
