Yes clomid will increase test levels. It has been shown effective at 25 mg day, and more isnt better. Its been shown to be effective at treating low t and infertility. Its also a staple in most peoples pct regimen. If you just wanna boost your test then I suggest using unleashed. Its a natty test booster that doesnt have the side effects of clomid, and doesnt have a negative effect on your bodies own production. You can stack it with postcycle for phenominal results.
