Carrier Oils

I’m in the same situation. Some people have no problems with MCT, but others get really bad PIP from it. Have you tried using cottonseed or sesame oil, or is grapeseed the only carrier that works for you?

Grapeseed has been the only one. Do you know of any suppliers that offer grapeseed besides simply steroids?

Mct is the preferred carrier oil right now. We make some with GSO for clients that request it.

@Juicyjohn , I feel your pain, brother. PIP can literally ruin a cycle, but before you hunt down GSO (Grapeseed Oil) as your only solution, let me share something I’ve learned after years of analyzing clinical-grade vs. UGL production.
Most people blame MCT for their PIP, but in 90% of cases, the oil isn't the problem the solvents are.
UGLs (Underground Labs) often over-use Benzyl Alcohol (BA) or use low-grade Benzyl Benzoate (BB) to compensate for raw powders that aren't 99% pure. High BA concentrations are what actually "bite" the muscle tissue. Furthermore, if the oil isn't filtered to 0.22 microns in a sterile, temperature-controlled environment, you're getting micro-particulates that cause an immune response (the "lump" and heat you feel).
The "Pharma Grade" Secret:
European pharmaceutical-grade products often use Miglyol 812 or ultra-refined MCT, but the reason they don't cause PIP isn't just the oil it's because the hormone purity is so high that they only need the absolute minimum of solvents.
Grapeseed Oil (GSO) is actually riskier if it’s not medical-grade. Most UGL GSO is food-grade, which has a higher oxidation rate and can contain traces of pollens that trigger localized allergic reactions.
If you’re sticking to U.S. domestic UGLs, you’ll keep running into this "solvent-heavy" issue regardless of the oil. If you ever get the chance to try EU-manufactured pharma-grade (the stuff made in actual labs, not basements), you'll realize that MCT is actually the smoothest carrier for absorption once the chemistry is done correctly.
Don't settle for "less painful" gear; look for "higher purity" gear. Your muscle tissue will thank you in the long run.

Everyone's physical constitution is different, so reactions to various carrier oils may vary. This is normal; simply choose the one that suits you best.
However, these oil-based products are currently quite difficult to find.
