Good morning and welcome. You pose a very interesting question. These chemicals have not been studied and aren't listed in any of my supplement manuals. However, I can tell you what I do know.
1.If a supplement cannot be found in any professional supplement reference, then I would be immediately cautious and concerned.
2. These chemicals are structured to boost testosterone production and to sustain the anabolic effects over a longer period of time.
3.Popular literature claims that these compounds have negative androgenic effects as well as negative estrogenic effects.
4.I also want to pose some potential side-effects for you to be aware of:
anxiety, loss of hair, anger or mood problems, insomnia, acne, greasey skin, diarhhea
5.Effects have been stated to take effect within two weeks.

I hope this information has helped to answer your question. Be well. Kathryn Shattler, MS,RDN

Hello, I recognize this question as coming around awhile back.I can be a little more specific this time around.

I learned that Dihydrotestosterone (DHT) is a derivative of Testosterone that is known as being more potent at signalling through the androgen receptor, and due to this it is involved to a larger degree in hair loss and prostate cancer.
(Examine.com)

7-Arimatase is one of the enzymes , one of which is to convert androgens (like testosterone) to estrogens. For more, see: anti-estrogen/aromatase inhibitors in your searches.

I have looked these products up in two major databases and not much is coming up on them. If you look in the archives you will find a previous answer of mine to this question. I suggest you refer to that and the additional information I have provided.

Another tidbit. I don't know what the delivery system is, but 7 arimatase is an enzyme. Enzymes are denatured in the hydrochloric acid of the stomach and become useless unless contained in a protective coating.

I have access to two large databases and your supplement is not in either one of them.

However, if you were my client I would discourage you from using these particular products not only because of immediate side-effects, but potential dangers down the road. And, still, any manufacturer that tries to fool or mislead a customer is not to be trusted. So, check out how your enzyme is being delivered - in a liquid or not advertised as being bioavailable then you aren't even getting what the label says.

The best way to build muscle is to eat correctly, get a good trainer, and if you use protein supplements, stick to isolated whey with BCAAs.
