I had an idea of to soak your nuts in some epsom salts and warm water for a couple of hours to reduce swelling. Also some ice packs might not be a bad idea. Be prepared beforehand if you do this.
I found the perfect remedy for this with a very HIGH libido, like I had. I tried the C.A. with 100mg/day, which had little effect for a while. I tried C.A. + Tamoxifen combo for 3-5 days, with little effect. Before, you inject your nuts, try this combo. It is a little pricier, but is guaranteed to decrease libido to castrate levels on the strongest of libidos AND you don't have to inject your nuts. This will kick in in less than a month, with no side effects, for me anyway, other than greatly decreased T levels. Cyproterone Acetate(100mg/day, gradually decreasing dosage every 3-4 months) + Tamoxifen (20mg/day, for no man boobs, as well as helps control libido, from what I've heard) + Dutasteride (.5 mg/day, pricier, but more effective) OR finasteride (5mg/day, cheaper, but this is what I started out on and it definitely KICKS ASS!) This will knock your T levels down to virtually nothing.
The label on the bottle does not suggest it is 1 molar, it definitively says it. The capital M is the definitive abbreviation for "molarity" or "molar".
