So I go to a naturopath who started me on testosterone self injections a couple of months ago. It did NOT give me noticeable increase in strength/endurance. What it did do was make me think about sex so much I got noticeably less done. Plus makes mismatch with menopausal wife worse and I really cannot get into injections. She recommended instead capsules Heart & Soil Whole Package which she started her hubby on and he likes better because it does not ramp up the libido. Supposedly a bull testicle product. She said instead of the weekly rush of testosterone which isn't natural, you can tailor you intake. Start with 2 daily and up to 6 daily is the range recommended. Pass this on in case it might suit someone to try it.
