Here’s a novel concept: you get bloodwork done out of pocket privately online for like $65 while you take exogenous hormones so you can see the real effects of playing God over your endocrine system with mystery chemicals, so you can make educated decisions in near real time about their effects on you.
Drugs effect people differently. Factor in all the fake, spiked, under/overdosed SARM products out there and you have a recipe for mixed feedback.
Your best bet for safety is to research trusted, 3rd-party verified sources of the product you desire and then actively monitoring your health during the administration protocol. Without bloodwork, you cannot be sure how you’re responding to what you’re taking.
Also, anything consumed orally is going to make the liver work harder to process it. That doesn’t necessarily mean it’s dangerous. Again, this is going to be individual & dose dependent (amount and duration of use).
